Open source FX Trading

easycrom · March 6, 2009

I have gotten so much from this site that I decided to share my EA.

IF it is profitable for you, make a donation to an account I specify.

If you modify let me know so we can test it; and if its better than my method, credit will be given to the modder and I will not ask for any donation.

Logic of the ea ( ideally ): Calculate average ATR for 4 hour candles for currency of your choice for the previous year.

Attach EA to 1 hour chart

Caveat: I am too lazy to do this right now so if someone could get me a CSV file with live data it would be much appreciated.

Any questions feel free to ask.

I am not charging for this because you are not fools, I am not a scammer ( the website listed in the code is just for fun ), and KNOWLEDGE SHOULD BE SHARED FREELY.

STRANGE I COULD NOT ADD THE ATTACHMENT CODE FOLLOWS

-edited. if you like to share your code. its better if you add "code" on it.

-and. you can have .hist or csv on this site

Re: Open source FX Trading

You are welcome, the backtest results for 2008 for GBPUSD and EURUSD using 20:1 leverage are good, 5k to 13k for GBPUSD and 5k to 17k for EURUSD. I just want someone to forward test it, as I have heard that demo prices are smoothed.

Also a weakness of this system is that it uses no stop loss so implement your own money management rules.

Re: Open source FX Trading

Can someone help me figure out why a profitable trade is re-entered, it seems to contribute to my drawdown.

William1713006271 · May 7, 2009

Re: Open source FX Trading

Double trades? Hmm... I haven't read your EA throughly but I think the problem is one of these:

- when a condition is fulfilled, you need to check if it won't be entered again in the same candle. Because usually in the same candle / bar, when the tick is changed you get entered multiple times, coz the condition would be the same. Normally we solve this by entering the trade only if the volume is zero. So, put something like (if volume=0 {do trade} else {no trade})

- another more versatile solution would be to create a flag to check if the trade is positive or not.

Regards,

easycrom · May 7, 2009

Re: Open source FX Trading

I would opt for the more versatile solution but I honest have no idea how to implement it, and what is worse the EA works pretty well except for the multiple trades. Sometimes the multiple trades end in multiple profits but I like the idea of taking my money once and thats it.

William1713006271 · May 8, 2009

Re: Open source FX Trading

if (profit) {do trade} else {no trade}

how to check profit? Try this

// put the if inside the [OrderSelect] loop
if (TP_Reached(OP_BUY,OrderOpenPrice())==true){/* do trade */}

bool TP_Reached(int cmd,double OP){

  bool isReached=false;

  if(TP!=0){

     if ((cmd==OP_BUY) && (Bid >= OP + TP*Point))isReached=true;

     else if ((cmd==OP_SELL) && (Ask <= OP - TP*Point))isReached=true;

  }

  return(isReached);

}

You can then put flags anywhere you want.

Hi william, what do you mean by put flags anywhere you want? sorry i'm not familiar with robots....thanks easycrom for sharing... :shand:

Well, flags are basically a programming technique, not just specific to EA or mql. So we can use flags anywhere. It's simple to understand and do but needs quite a long explanation to understand. Try googling "programming flag" without quotes.

Regards,

easycrom · May 8, 2009

Re: Open source FX Trading

I dont know enough about programming to understand that code :( but I will give away the way I use this system manually

Once I see the setup, I place the orders with an expiry of 24 hours.

If the trade is profitable 24 hours later I trade in the opposite direction. Now for my least favourite part, if the trade goes against me to the point that it reaches the other end of the set up bar, I double my order and trade in the opposite direction with a trailing stop of 100.

Now I have blown up several accounts using this method and 20:1 leverage per trade per currency, not one ended in me not being able to draw out my initial investement and a 10% profit though, but CLEARLY it needs improvement, and you can implement whatever stop losses you deem.

The backtesting is heartbreaking as the current robot can double your account but ALWAYS ENDS UP IN A MARGIN CALL.

A friend of mine recommended that I go long 10 pips above the high/low with a target of 100 pips and a stop loss of 50 pips.

So there you have it, wishing you profitable trades.

easycrom · August 10, 2009

Re: Open source FX Trading

the method is profitable i just dont know how to stop it from making multiple trades at the same price point

cacus · August 11, 2009

Re: Open source FX Trading

Maybe checking the bars from last trade and adding a time limit between orders...

I've made that for and EA of mine some time ago to limit it trading after a loss, so the EA waits X days far from last lost.

You can search in history for the last closed trade with your MagicNumber and if OrderCloseTime()+(offset time between orders you like) > TimeCurrent() then it's able to enter another order. else, wait.

To check last trade time i suggest this:

double CheckLastOrderTime(){

if (OrdersHistoryTotal()>0){

OrderSelect(OrdersHistoryTotal()-1,SELECT_BY_POS,MODE_HISTORY);

if (OrderMagicNumber()==MagicNumber){return(OrderCloseTime());}

}else {return(-1);}

}

If this function returns -1 then that means that the EA is able to trade, also, it's able to trade if CheckLastOrderTime()+(delayBetweenOrders)>TimeCurrent(). Else, don't trade.

EDIT: delayBetweenOrders should be the numbers of seconds you would like the EA to wait, you can multiply this by 3600 to use hours and so on...

Hope i can give you some help on it.

I'm out of time but if you don't get it i'll try later.

Regards.

Re: Open source FX Trading

thanks futron because the way i had approached was to use OrderProfit()

for longs i had stated that if OrderProfit() < High [0] then place trade
