Please help me correct this code error on line 59.
Here is the code in the attachment.
The error is 'WPR_Period' - cannot convert enum

Your usage of indicators is wrong. You need to create the indicator once in OnInit. You get a handle, use the handle with CopyBuffer to get the data.
Your parameters are wrong, you place the cursor on the function name and then press F1 to open the documentation.

This
iWPR(Symbol(), WPR_Period, i);
Should be
iWPR(Symbol(), 0, WPR_Period, i);
You are right, I supposed it to be MQL4 but it is MQL5...
So @progress chukwu as you can see in a lot of free code around here, on MQL5 you need to declare and assign indicator handles into OnInit, and CopyBuffers into OnTick/OnCalculate.
