Error 0 when trade doesn't open

I'm writing an EA which when it's trading logic is met is supposed to open 2 market orders using the same values. Sometimes both these orders open, and sometimes they dont. For a while I had errors where the second order wouldn't open, and I got an error code. I have fixed that error by using RefreshRates between sending order 1 and 2. However, now I seem to regularly be getting only the second order opening. First I didn't get any error at all, so I went back to the mql4 file and looked at it very carfully, and then moved a bracket around the Else" part of the statement, thinking that was the problem. Today I have come home and discvered the same thing has happened, but this time I have an error message. I looked up the 0 code, only to discover it meant I had no error.

So please, if there is no error, why isn't my trade opening??!! It's like it isn't even tryin to open it, but then other times they boh open fine, using exactly eht same lines of code!

Does anyone have any idea of why this might be?

This is my trade opening logic. I curently always have trailing stop set to higher than 0.

static datetime Time.newBar;

bool newBar = (Time[0] > Time.newBar);

if (newBar)

{ // A new bar began.

Time.newBar = Time[0]; // Reset static.

//... <<<< Any code here is executed only when a new bar appears

if ((bflag==false) && (sflag==false)) //No current trades open

{

//Alert("Check each tick section");

//open buy trade

if (buy == true) //buy trade
