Right now, I am stuck on coding for openning position of multiple currencies, since sendorder() function only knows symbol() for the running chart.
Please someone give me some sample on how to code that subject.

The Idea of my EA is to open position of several pairs on particular time ( ie. EURUSD, USDJPY at 4AM ).

Thanks before.

If you need open a position for a pair which is different than the chart you attach the EA, the Symbol() function must be replaced by the pairs you need (ie "EURUSD" "EURJPY" ... etc).

Dont forget to add the "m" or whatever is after the pair name if your broker add.

Hi ,

How could I calculate if some new bar added to my chart in any timeframe?

Thank you very much.

This function will do the trick...

Code:

bool NewBar() {

	static datetime LastTime = 0;

	if (Time[0] != LastTime) {
		LastTime = Time[0];		
		return (true);
	} else
		return (false);
}

How can I know when the market is say an hour from the Friday closing or right at market close? I use demo accounts with two different brokers and they are on different server times and I would like to code my EA to close all open positions before the Friday market close. This is just for testing puposes but it is something I would like to know regardless. I don't want to hard code a time due to the fact that different brokers use different server times. Is this possible? I know I can detect market opening but due to the gap behavior seen at times on market openings I would be more comfortable closing positions before the Friday market close.
Thanks!

Hi ,

Is any way to pass one indicator variable to an expert advisor?

For example if I have 2 moving averages and one cross the other or one is greater than other and store them in 2 variables in my indicator as MA1 and MA2.

Is it possible to call these variables to expert advisor?

Note: I don't want to put the code of Moving averages in the expert advisor , generally I want to take some variables from indicator and put in an expert advisor. (Something like read the variable from memory).

Thank you very much.

You must use the iCustom() function in your EA to call the different indicator buffers.

Or for the standard indicators, use their standard functions. Example for MA: iMA(......);

Hi,

Just a quick question, does anyone know if there is a piece of code I can use so the text and values do not appear on the custom indicator window, as in the pic below.

thanks

By giving a NULL value to the desired buffer: SetIndexLabel(X,NULL);
