I'm writing my first EA from nearly scratch after successfully making a few mods to an EA found on the web. I'm puzzled by an error statement I get when I run the code through the compiler.

The code is:

//=====================================

int start()

if(OrdersTotal()<1) {
OrderSend(Symbol(),OP_BUY,Lotsi,Ask,slippage,-25*Point,25*Point,0,0,0,Blue);
Clotsi = Lotsi;
return(0);
}

//=====================================

The error message is:

"if" - semicolon expected


//=====================================

I have tried placing a semicolon at several different locations but get the same message. At this point in time I have only one "if" statement in the EA --- more will follow if I get past this point.

I'm it must be something simple, but I can't figure it out from the examples in the manual another info I have found thus far.

Any help you can offer is appreciated.

maybe an opening brace, "{", after "start()" ?

Post your whole code here, so we can read it and point you the place to put semicolon.

Thanks, ralph.

The opening brace solved the problem.

I need modification of indicator T3 TRIX to read the value from indicator Moving Averages (iMA). I very expecting for your help

Ralph & Kalenzo, thanks for your reponse a couple days ago.

I have completed the EA and it clears the compiler with no errors and loads successfully in the stategy tester, but does not produce any results. Any thoughts?

Here is the entire code, but first let me say I have no illusions as whether this EA can produce a profit. I am simply trying to write an EA start to finish get it to run. This EA is a modified version of the Blessing strategy with a d'Alembert money managemenet system instead of the Martingale MM.

extern int slippage = 5;
extern double Lotsi = 0.1;
extern int stoploss = 25;
extern int takeprofit = 25;

int cnt = 0;

bool EnableTrading = true;

The stoploss and takeprofit parameters to OrderSend are "price values" and not pips. Try using "Ask-stoploss*Point" and "Ask+takeprofit*Point" instead; when it comes to EA writing, not only the trend is your friend, but so is the manual ;-)

Ralph,

Thank you very much for your patient and polite responses. I know the mistakes were really dumb ones. As a beginner I didn't know where to begin when the EA passed muster with compiler, and the Strategy Tester said it loaded successfully, but would not produce any results.

Prior to posting my request I had actually tried something close (but obviously not correct) to what is in the manual. That earlier version passed muster with the compiler, but the Stategy Tester rejected the OrderSend syntax. So I looked at the OrderSend statement in the EA that I had made some mods to, to see its syntax. That's where I derived the bad syntax. What I now understand is the author of that EA prefined "stoploss" and "takeprofit" using the correct syntax before the OrderSend statement is executed.

Have some programming experience with Fortran and Basic, but the MQL4 language is challenging for me right now.

Thanks again for your succint and polite responses. They were most helpful.

BTY Now that the EA runs I can see I have a couple logic errors in the EA as well, but I'll figure those out now that I have the syntax issues behind me.

hi everyone,
thumbs up to you guy for having a heart to help. i am trying to convert a straddle ea to script can anyone give me an idea how to go abt it?
thanks in advance

some kind of script that monitors the trades until it reaches a preset profit so that as soon as the trades starts coming down after exceeding the preset profit it must close all trades on that currency. But if the profit goes up beyond the preset , it should trail the preset amount not individual trade.
