Hi, Am I correct, that there is no function or system-variable that tells a class whether it is called by an indicator, expert or a script?
Hi,   1st, sorry my english.   I have crossing moving avarage robot, but if it has an open order, dont open another order until have closed the previous.     This is the problem? Thank you   
I have never considered this before. I just wondered if anybody actually knows the order of an iCustom() call in an EA. Is the iCustom executed before the the code in OnTick that uses the value? I ask this because I am currently working on a project where the iCustom call is only executed on a new...

I would like both EAs to have the ability to trade ALL cross-connected instruments regardless of prefix or postfix or whatever chart the EA is operating on, this will save me having multiple charts open with multiple EAs running on both MT4 terminals and reduce CPU/RAM lag. Hope you guys can help.

If you use an Expert does it automatically liquidate you position if you end it? Or do you keep the last position until you close them manually? EX: If the Expert Buy 1 lot of USDJPY and you want to end the Expert does it automatically sell any open positions it created?

If moves forward, backward graph,...

Hi everybody, I come to you because I need a clarification. So I programmed an Expert advisor, he uses the ATR as SL. What I would like to be able to do is tell my expert advisor not to take into account the SL of the ATR if it is more than 200 pips for example. If the ATR wants to place an SL at...
