Hello Im programming an EA that analizes the 300 bars prior to the current bar. So If I try to backtest in the begginning of my data I get the "array out of range" because the bars.


How I should handle this one? I mean I want the code to analize if there is enough bars to run the EA in the backtest (300> in this case more or less)


Could anybody help?


Thank you

A solution depends on your code.

My code reads the x number of bars with the same time for y days.

Meaning it reads the values of the 17:00 H1 bar of the priors 10 days. As you can image at the beggining there are not 10 days to read, so then its when it gives the array out of range error.

1) Did you check the size of the array?

2) Did you check the no. of available bars?
