    An Essay on How Forex Brokers Truly Work

    Originally posted by Darkstar at Forex Factory. A truly awesome essay on how the Forex "market" and the banks and brokers behind it.

    I thought this would be particularly good to add here to this forum given much of the talk of starting brokerages and the evils of market makers...

    Enjoy!

    ---original post---

    There has been much discussion of late regarding broker spreads and liquidity. Many assumptions are being made about why spreads are widened during news time that are built on an incomplete knowledge of the architecture of the forex market in general. The purpose of this article is to dissect the market and hopefully shed some light on the situation so that a more rational and productive discussion can be undertaken by the Forex Factory members.

    We will begin with an explanation of the purpose of the Forex market and how it is utilized by its primary participants, expand into the structure and operation of the market, and conclude with the implications of this information for speculators. With that having been said, let us begin.

    Unlike the various bond and equity markets, the Forex market is not generally utilized as an investment medium. While speculation has a critical role in its proper function, the lion’s share of Forex transactions are done as a function of international business.

    The guy who buys a shiny new Eclipse more then likely will pay for it with US Dollars. Unfortunately Mitsubishi’s factory workers in Japan need to get their paychecks denominated in Yen, so at some point a conversion needs to be made. When one considers that companies like Exxon, Boeing, Sony, Dell, Honda, and thousands of other international businesses move nearly every dollar, real, yen, rubble, pound, and euro they make in a foreign country through the Forex market, it isn’t hard to understand how insignificant the speculative presence is; even in a $2tril per day market.

    By and large, businesses don’t much care about the intricacies of exchange rates, they just want to make and sell their products. As a central repository of a company’s money, it was only natural that the banks would be the facilitators of these transactions. In the old days it was easy enough for a bank to call a foreign bank (or a foreign branch of ones own bank) and swap the stockpiles of currency each had accumulated from their many customers.

    Just as any business would, the banks bought the foreign currency at one rate and marked it up before selling it to the customer. With that the foreign exchange spread was born. This was (and still is) a reasonable cost of doing business. Mitsubishi can pay its customers and the banks make a nice little profit for the hassle and risks associated with moving around the currency.

    As a byproduct of transacting all this business, bank traders developed the ability to speculate on the future of currency rates. Utilizing a better understanding of the market, a bank could quote a business a spread on the current rate but hold off hedging until a better one came along. This process allowed the banks to expand their net income dramatically. The unfortunate consequence was that liquidity was redistributed in a way that made certain transactions impossible to complete.

    It was for this reason and this reason alone that the market was eventually opened up to non-bank participants. The banks wanted more orders in the market so that a) they could profit from the less experienced participants, and b) the less experienced participants could provide a better liquidity distribution for execution of international business hedge orders. Initially only megacap hedge funds (such as Soros’s and others) were permitted, but it has since grown to include the retail brokerages and ECNs.

    Market Structure:

    Now that we have established why the market exists, let’s take a look at how the transactions are facilitated:

    The top tier of the Forex market is transacted on what is collectively known as the Interbank. Contrary to popular belief the Interbank is not an exchange; it is a collection of communication agreements between the world’s largest money center banks.

    To understand the structure of the Interbank market, it may be easier to grasp by way of analogy. Consider that in an office (or maybe even someone’s home) there are multiple computers connected via a network cable. Each computer operates independently of the others until it needs a resource that another computer possesses. At that point it will contact the other computer and request access to the necessary resource. If the computer is working properly and its owner has given the requestor authorization to do so, the resource can be accessed and the initiating computers request can be fulfilled. By substituting computers for banks and resources for currency, you can easily grasp the relationships that exist on the Interbank.

    Anyone who has ever tried to find resources on a computer network without a server can appreciate how difficult it can be to keep track of who has what resources. The same issue exists on the Interbank market with regard to prices and currency inventory. A bank in Singapore may only rarely transact business with a company that needs to exchange some Brazilian Real and it can be very difficult to establish what a proper exchange rate should be. It is for this purpose that EBS and Reuters (hereafter EBS) established their services.

    Layered on top (in a manner of speaking) of the Interbank communication links, the EBS service enables banks to see how much and at what prices all the Interbank members are willing to transact. Pains should be taken to express that EBS is not a market or a market maker; it is an application used to see bids and offers from the various banks.

    The second tier of the market exists essential within each bank. By calling your local Bank of America branch you can exchange any foreign currency you would like. More then likely they will just move some excess currency from one branch to another. Since this is a micro-exchange with a single counterparty, you are basically at their mercy as to what exchange rate they will quote you. Your choice is to accept their offer or shop a different bank. Everyone who trades the forex market should visit their bank at least once to get a few quotes. It would be very enlightening to see how lucrative these transactions really are.

    Branching off of this second tier is the third tier retail market. When brokers like Oanda, Forex.com, FXCM, etc. desire to establish a retail operation the first thing they need is a liquidity provider. Nine in ten of these brokers will sign an agreement with just one bank. This bank will agree to provide liquidity if and only if they can hedge it on EBS inclusive of their desired spread. Because the volume will be significantly higher a single bank patron will transact, the spreads will be much more competitive. By no means should it be expected these tier 3 providers will be quoted precisely what exists on the Interbank. Remember the bank is in the business of collecting spreads and no agreement is going to suspend that priority.

    Retail forex is almost akin to running a casino. The majority of its participants have zero understanding how to trade effectively and as a result are consistent losers. The spread system combined with a standard probability distribution of returns gives the broker a built in house advantage of a few percentage points. As a result, they have all built internal order matching systems that play one loser off against a winner and collect the spread. On the occasions when disequilibrium exists within the internal order book, the broker hedges any exposure with their tier 2 liquidity provider.

    As bad as this may sound, there are some significant advantages for speculators that deal with them. Because it is an internal order book, many features can be provided which are otherwise unavailable through other means. Non-standard contract sizes, high leverage on tiny account balances, and the ability to transact in a commission free environment are just a few of them…

    An ECN operates similar to a Tier 2 bank, but still exists on the third tier. An ECN will generally establish agreements with several tier 2 banks for liquidity. However instead of matching orders internally, it will just pass through the quotes from the banks, as is, to be traded on. It’s sort of an EBS for little guys. There are many advantages to the model, but it is still not the Interbank. The banks are going to make their spread or their not go to waste their time. Depending on the bank this will take the form of price shading or widened spreads depending on market conditions. The ECN, for its trouble, collects a commission on each transaction.

    Aside from the commission factor, there are some other disadvantages a speculator should consider before making the leap to an ECN. Most offer much lower leverage and only allow full lot transactions. During certain market conditions, the banks may also pull their liquidity leaving traders without an opportunity to enter or exit positions at their desired price.

    Trade Mechanics:

    It is convenient to believe that in a $2tril per day market there is always enough liquidity to do what needs to be done. Unfortunately belief does not negate the reality that for every buyer there MUST be a seller or no transaction can occur. When an order is too large to transact at the current price, the price moves to the point where open interest is abundant enough to cover it. Every time you see price move a single pip, it means that an order was executed that consumed (or otherwise removed) the open interest at the current price. There is no other way that prices can move.

    As we covered earlier, each bank lists on EBS how much and at what price they are willing to transact a currency. It is important to note that no Interbank participant is under any obligation to make a transaction if they do not feel it is in their best interest. There are no “market makers” on the Interbank; only speculators and hedgers.

    Looking at an ECN platform or Level II data on the stock market, one can get a feel for what the orders on EBS look like. The following is a sample representation:



    You’ll notice that there is open interest (Level II Vol figures) of various sizes at different price points. Each one of those units represents existing limit orders and in this example, each unit is $1mil in currency.

    Using this information, if a market sell order was placed for 38.4mil, the spread would instantly widen from 2.5 pips to 4.5 pips because there would no longer be any orders between 1.56300 and 1.56345. No broker, market maker, bank, or thief in the night widened the spread; it was the natural byproduct of the order that was placed. If no additional orders entered the market, the spread would remain this large forever. Fortunately, someone somewhere will deem a price point between those 2 figures an appropriate opportunity to do something and place an order. That order will either consume more interest or add to it, depending whether it is a market or limit order respectively.

    What would have happened if someone placed a market sell order for 2mil just 1 millisecond after that 38.4 mil order hit? They would have been filled at 1.5630 Why were they “slipped”? Because there was no one to take the other side of the transaction at 1.56320 any longer. Again, nobody was out screwing the trader; it was the natural byproduct of the order flow.

    A more interesting question is, what would happen if all the listed orders where suddenly canceled? The spread would widen to a point at which there were existing bids and offers. That may be 5,7,9, or even 100 pips; it is going to widen to whatever the difference between a bid and an offer are. Notice that nobody came in and “set” the spread, they just refused to transact at anything between it.

    Nothing can be done to force orders into existence that don’t exist. Regardless what market is being examined or what broker is facilitating transactions, it is impossible to avoid spreads and slippage. They are a fact of life in the realm of trading.

    Implications for speculators:

    Trading has been characterized as a zero sum game, and rightly so. If trader A sells a security to trader B and the price goes up, trader A lost money that they otherwise could have made. If it goes down, Trader A made money from trader B’s mistake. Even in a huge market like the Forex, each transaction must have a buyer and a seller to make a trade and one of them is going to lose. In the general realm of trading, this is materially irrelevant to each participant. But there are certain situations where it becomes of significant importance. One of those situations is a news event.

    Much has been made of late about how it is immoral, illegal, or downright evil for a broker, bank, or other liquidity provider to withdraw their order (increasing the spread) and slip orders (as though it was a conscious decision on their part to do so) more then normal during these events. These things occur for very specific reasons which have nothing to do with screwing anyone. Let us examine why:

    Leading up to an economic report for example, certain traders will enter into positions expecting the news to go a certain way. As the event becomes immanent, the banks on the Interbank will remove their speculative orders for fear of taking unnecessary losses. Technical traders will pull their orders as well since it is common practice for them to avoid the news. Hedge funds and other macro traders are either already positioned or waiting until after the news hits to make decisions dependent on the result.

    Knowing what we now know, where is the liquidity necessary to maintain a tight spread coming from?

    Moving down the food chain to Tier 2; a bank will only provide liquidity to an ECN or retail broker if they can instantly hedge (plus their requisite spread) the positions on Interbank. If the Interbank spreads are widening due to lower liquidity, the bank is going to have to widen the spreads on the downstream players as well.

    At tier 3 the ECN’s are simply passing the banks offers on, so spreads widen up to their customers. The retailers that guarantee spreads of 2 to 5 pips have just opened a gaping hole in their risk profile since they can no longer hedge their net exposure (ever wonder why they always seem to shut down or requote until its over?). The variable spread retailers in turn open up their spreads to match what is happening at the bank or they run into the same problems fixed spreads broker are dealing with.

    Now think about this situation for a second. What is going to happen when a number misses expectations? How many traders going into the event with positions chose wrong and need to get out ASAP? How many hedge funds are going to instantly drop their macro orders? How many retail traders’ straddle orders just executed? How many of them were waiting to hear a miss and executed market orders?

    With the technical traders on the sidelines, who is going to be ****** enough to take the other side of all these orders?

    The answer is no one. Between 1 and 5 seconds after the news hits it is a purely a 1 way market. That big long pin bar that occurs is a grand total of 2 prices; the one before the news hit and the one after. The 10, 20, or 30 pips between them is called a gap.

    Is it any wonder that slippage is in evidence at this time?

    Conclusions:

    Each tier of the Forex market has its own inherent advantages and disadvantages. Depending on your priorities you have to make a choice between what restrictions you can live with and those you cant. Unfortunately, you can’t always get what you want.

    By focusing on slippage and spreads, which are the natural byproduct of order flow, one is not only pursuing a futile ideal, they are passing up an enormous opportunity to capitalize on true inefficiencies. News events are one of the few times where a large number of players are positioned inappropriately and it is fairly easy to profit from their foolishness. If a trader truly wants to make the leap to the next level of profitability they should be spending their time figuring out how identify these positions and trading with the goal of capturing the price movement they inevitably will cause.

    Nobody is going to make the argument that a broker is a trader’s best friend, but they still provide a valuable service and should be compensated for their efforts. By accepting a broker for what it is and learning how to work within the limitations of the relationship, traders have access to a world of opportunity that they otherwise could never dream of capturing. Let us all remember that simple truth.

    ---end of originial copy and beginning of my commentary---

    Seriously, I found this incredibly illuminating. ECN is not always the true solution, it depends on the type of trading you are engaged in. Market making brokers actually do have some beneficial usages. It sounds bad but ultimately, knowledgeable traders can actually make money off of less skilled retail traders in a market making brokerage.

    Things to contemplate....

    Electronic Communications Network — ECN Forex brokers additionally allow client orders interact with other clients' orders. ECN Forex broker provides a marketplace where all its participants (banks, market makers and individual traders) trade against each other by sending competing bids and offers into the system. Participants interact inside the system and get the best offers for their trades available at that time. All trading orders are matched between counter parties in real time. ECN brokers charge commission for trading and have always have variable spreads.

    Hi Verbtheory,

    Agree with your essay, especially in your conclusions, Contacted a broker awhile back wanting to know their gmt time so I could set my Ea accordingly, I mistakenly told them I have a Newstrader Ea. First thing they said was, Newstrading Ea's are FROWNED upon, because they take advantage of the market, and right away this person wanted to know the name of the Ea. and a lot of specifics which I refused to tell.Anyway long story short didn't need the GMT time, the Ea was figuring it automatically and it is doing very well on demo and if it continues will take it live, but will somehow try to make it stealthier.

    Re: An Essay on How Forex Brokers Truly Work

    Here is part of a post from 4xtrader on tsd in 2007.
    It is a letter written by Bill Williams in 2006, giving his reasons for not trading [spot] forex. (He trades currency Futures).
    I think it is a good addendum to the above essay.

    10.07.2006
    ....reasons
    why I do not trade Forex
    bill wms

    WHEN TO NOT TRADE FOREX
    Because so many people bombard us with requests
    about forex, we teach people how to trade it.
    Better to teach them the right way than to let
    them commit financial suicide. Nevertheless, we
    do not advocate forex trading unless you have a
    particular reason as to why you need to trade
    during the middle of the night, or you have a
    specific need to trade in currency pairs that
    do not involve the U.S. dollar. If the U.S.dollar
    is involved and you are able to trade during U.S.
    market hours (7:20am-2:00pm U.S.Central Time) you
    are much better off trading currencies in the
    Chicago currency futures markets. Here is the
    reason why:

    * Brokers deceive you about there being no com-
    missions. $30 minimum/round turn(called spread)
    is in reality a commission that eats up your
    capital at an astonishing rate. Even winning
    traders lose money and end up with negative
    results because of this outlandish overhead.
    Trading futures, you never have to pay a broker
    more than $10/round turn, and usually quite a
    bit less than that.

    * Guaranteed fills. True but... The only way a
    broker can guarantee fills is for the broker to
    become the buyer or seller of last resort. That
    means the broker is running a bucket shop. All
    forex brokers are the buyer and seller of last
    resort.

    * Brokers do not tell the truth about volume.
    They show the volume for all forex trading,
    which doesn't even come close to the volume
    they truly have at their own brokerage, which
    is where you are trading. Volume in currency
    futures is considerably higher than the volume
    traded at any single forex broker, often great-
    er by a factor of ten.

    * Leaning. Brokers say they are charging you a
    3 pip spread to trade the popular currency
    pairs. But in reality a broker may be making
    as much or more than 10 pips on your trades.
    He does this by skewing prices. Since you are
    not trading at an exchange, the broker can
    feed you any price he wants to feed you. He
    can buy at the bank for perhaps 7 pips less
    than he sells to you. He then charges you 3
    pips for the privilege of being ripped off for
    a total of 10 pips.

    * Unregulated. Forex may sound like an exchange
    but it isn't. It exists entirely in cyberspace
    with every broker and every bank having diff-
    erent prices for any particular currency.There
    is no regulation,even for brokers who register
    with the CFTC and the NFA. Forex brokers do
    not have to mark to market each day as do
    futures brokers. If your forex broker files
    for bankruptcy or absconds with your money you
    have zero recourse.

    * No guarantee. If a forex broker does go out
    of business, you could lose all your money.
    There are no guarantees and no one standing
    behind it. Futures brokers are required to
    mark to market every day. They have to put up
    cash to cover every open trade on their books.
    Future brokers have gone broke, but no future
    customer has ever lost one cent of the money
    in his trading account because of a failed
    broker. Nor have they had to wait for their
    money. It is immediately available.

    * You can get exactly the same action in the
    euro fx futures as you get in the"Euro" forex.
    Commissions are as low as one tenth per round
    turn depending on volume, through a regulated
    broker, trading electronically at an exchange
    where you know the true price of the currency.

    * What is the true price? A forex broker can only
    give you the price of a currency as quoted to
    him by the bank through which he trades. Banks
    have diffeing prices for a currency. You never
    know what the real price is because there is no
    central exchange through which all prices flow.
    Besides not knowing the true price from the
    bank, you can also be deceived by "leaning" or
    "skewing" of the real price at the bank. Forex
    brokers comonly lean the prices.

    * Forex brokers are not truthful. They lure
    people in with hype and false advertising: "No
    commissions!" "Guaranteed fills." "24 hour
    trading:" Who in their right mind is going to
    trade in the middle of the night unless they
    have a special need. While it is true that
    total forex volume is greater than in the
    futures, futures volume at the exchange is
    greater than the volume at your broker for the
    most popularly traded currencies. The only
    place where the liquidity differential matters
    is in currencies like the Mexican peso, the
    Brazilian real, and somebody's drachma. Those
    thinly traded currencies may be more liquid in
    forex. But if you trade anything but the few
    most liquid and popular currencies, you are
    going to be paying at least 5 pips, and often
    more. Unless you have a particular comercial
    need to deal in Polish ziotys, Indian rupees,
    or some other thinly traded currency, you don't
    need forex.

    * You are told by forex brokers that there is
    little or no stop running. This is one of their
    biggest and boldest fabrications. The truth is
    there is far more stop running in forex than in
    futures, and possibly as much stop running as
    in the stock market. I have friends who work in
    forex as well as many traders who of necessity
    have to trade forex. One of my students is a
    market maker in forex. These are people who
    should know, but in case you don't want to
    believe me or them, simple observation of forex
    trading will reveal the vast amount of stop
    running that takes place there. Who is it that
    runs the stop? It's your friendly forex broker,
    that's who. The broker has a vested interest in
    seeing to it that your orders are filled. Stop
    running is nothing more than order filling.
    The broker sees to it that everybody's orders
    get filled.

    * Probably you have heard that if your are win-
    ning regularly in forex, you may be barred from
    trading. Is this true? Yes it is. The fact that
    is true is just another proof that when you
    trade forex you are trading at a bucket shop.
    In the book, "Reminiscnces of a Stock Operator,
    " we are told that Jesse Livermore was banned
    from trading a certain stock brokers because
    they couldn't stand him beating the housel. The
    same thing is true with many forex brokers.
    Since they are the ones guaranteeing you a fill
    they in effect the buyer and seller of last re-
    sort. The truth is that most forex brokers have
    precious little liquidity at their firms. In
    order to give you the impression that there is
    liquidity, it is the broker who gives you your
    fill. It is the broker who does the stop run-
    ning that supposedly doesn't exist in forex.
    But if you are regularly beating the socks off
    the broker, he will ban you from trading at his
    firm.

    Now you know the truth about forex. I challenge
    any and all forex brokers to prove that I am
    wrong.
