how to multiple indicator ? ( mql4)

New comment
 

the question may be funny to someone , but ...... I created an indicator but it only works on one currency pair. How can I make it work on different timefrimes and many other instruments ?

Anyone could help me ?

Thanks :) 

 

It should work on other currency pairs quite simply, just use Symbol() in place of all your currency pair names.

Another difference between currency pairs might be the size of a point, so make sure to check that if you need to.

Similarly with timeframes you can use Period() in place of timeframes, although i'm not sure how to help you otherwise.

 
  1. Jay Tolar: Symbol() in place of all your currency pair names. Similarly with timeframes you can use Period() in place of timeframes, 

    You have it backwards. He wants other symbols/TF.

    You can't use any Predefined Variable for other symbols/TFs.

  3. "Doesn't work" is meaningless — just like saying the car doesn't work. Doesn't start, won't go in gear, no electrical, missing the key, flat tires — meaningless.

  4. On MT4: Unless the chart is that specific symbol(s)/TF(s) referenced, you must handle 4066/4073 errors before accessing candle/indicator values.
