{
ticket=OrderSend(Symbol(),OP_BUY,... );
ITradedOnThisBar = Bars;
}

Doing This will keep you from opening a trade on the same bar that you already opened a trade on, but more importantly you want to keep it from closing on the same bar so I would also add this code where you close your trade, for example:

if(Your Criteria && ITradedOnThisBar != Bars)
{
OrderClose(OrderTicket(),... ); // close position
}

This is probably the most simple way to do what you are trying to do.

Thanks for the coding. I have installed it in my ea (hopefully in the right spots), and will find out if it will work once the moving averages cross.

Thanks!

I wonder if there is such a code (w/ below description).

What would the basic code be w/ the following parameters ? (w/ an understanding that any indicator w/ a value could be plugged in)

(Opening trades)
1. A long trade is placed when an indicator's current value goes higher than previous bar's close value. (intrabar, not close)

2. A short trade is placed when an indicator's current value goes lower than previous bar's close value. (intrabar, not close)

(Closing trades)
1. Long trades are closed when short trades are opened.

2. Short trades are closed when long trades are opened.

thanks

I do not know how to code, but I have made several EA's simillar to what you describe using the expert advisor builder. I'm not sure if thats what you are looking for but you might check it out if you haven't already.

i'm sure someone has asked this already but i cannot find it when i search the threads.
i would like to know how to code for an EA to place a trade only when the price is between to levels -I.E.

if (price=>1.0000 && price< 1.0050) sell

Here...

PHP Code:


			
string price = (DoubleToStr(iMA(Symbol(),0,1,0,MODE_EMA,PRICE_CLOSE,0),Digits));



if (price=>1.0000 && price< 1.0050) 

{

sell order here

}
