Hi, everyone.
I'm almost new to mql4 programming but I have been around programming some time in other languajes. I'm trying to code an EA that runs at once several Strategies but I found a problem when coding,
as all Strategies use the same program but may have different parameters, when I code I have to check all parameters one by one. Let me explain.
For instance: Strategy1_SL_pips=40; Strategy1_Trail=true; and so on...
Strategy2_SL_pips=20; Strategy1_Trail=false; and so on...
So when I arrive at a point where I have to use them, i need to check every single Variable by its name.
For instance: if (Strategy1_Trail) { Do stuff;}
if (Strategy2_Trail { Repeat code; }
In other languajes U can get a Variable's Value by its name and do things like this:
string StrategyArray[]={"Strategy1","Strategy2"...};
for (int i=0; i<ArrayRange(StrategyArray,0);i++) {
if (GetValue(StrategyArray[i]+"_Trail")==true) { Do Stuff;}
}
Where GetValue is a function provided from the languaje.
I've seen that it can be made something like that with GlobalVariables but I didn't see how can I do with extern variables.
This issue would save me tons of repeated code and much less errors when upgrading or changing code. I would be grateful if someone tell me how to get a solution. Thanks in advance
