How to let the EA working on different cross

[Dario T.]

Hi Guys,

I have an EA that works properly on EURUSD...

Now I want it to work on others 10 different cross...

What is the best practice in this case ?

Should I have to implement a loop on each cross ?

Thanks to support!

curr[0]="EURGBP";
curr[1]="GBPUSD";
curr[2]="EURAUD";
...
...
curr[9]="NZDUSD";

for(int j=0; j<=9; j++)
  {
    if(ADX(curr[j])>0) Buy(curr[j],0.01);
    if(ADX(curr[j])<0) Sell(curr[j],0.01);
  }

something like this I think

Assuming it was coded to trade the current symbol, just put it on other charts. Done.

Do not trade multiple currencies in one EA.

• You can't use any {MT4: predefined variables, MT5: predefined variables,} can't use the tester, must poll (not OnTick,) and usually other problems, e.g. A problem with iBarShift - MQL4 and MetaTrader 4 - MQL4 programming forum- Page 2
• You must handle History {MT4: 4066/4073 errors: Download history in MQL4 EA - MQL4 and MetaTrader 4 - MQL4 programming forum , MT5: Timeseries and Indicators Access /  Data Access - Reference on algorithmic/automated trading language for MetaTrader 5.}
• Code it to trade the chart pair only. Look at the others if you must. (Don't assume that Time[i] == iTime(otherPair,TF, i) always use iBarShift.)
• Then put it on other charts to trade the other pairs. Done.
