Can't draw to the window.

New comment
 

Moving from mql4 to mql5 but can't even draw a rectangle,

tried:

ObjectCreate(0, "Rectangle", OBJ_RECTANGLE, 0, time[0], 1, time[5], 2)

just to get going but nothing is showing.

What's wrong?

Here's the full code:

                const double &close[],
                const long &tick_volume[],
                const long &volume[],
                const int &spread[])
  {

//--- return value of prev_calculated for next call
   return(rates_total);

Thanks.;‌

time[] is not indexed as series by default with mql5.

Add a line before ObjectCreate() :

ArraySetAsSeries(time,true);

‌Also I suppose price between 1 and 2 are visible on your chart.

Finally ObjectCreate() is a function, you should always check the return value.‌

 

Thanks, that worked for the rectangle.

Seems the same or buffers too

Thanks man..‌
