Getting maximum and minimum of the last 20 Bars

New comment
 

Hello all,

weeks ago I had a C-programming training. Now I will start to learn MQL5. I read some tutorials but I don`t know how I can get the maximum and minimum of bars to copy them into an own array.

Concretely I would like to create an array (e.g. double array_maximum[20]) and safe the maxima of the last 20 bars in that array.

 

Can someone please tell me which function I need to get the maxima of the last bars?

Welcome to mql5.com forum,

The maxima of a bar is high price, so for the maxima of the last 20 bars :

  double maxima[];
  CopyHigh(_Symbol,PERIOD_CURRENT,1,20,maxima);

Is it what you asked for ?

 

Thank you for promp reply. Thats exactly what I asked for!


Thank you!
