Automatic validation fails when publishing new indicator to market place for MT5

[ALEKSANDR SHUKALOVICH]

Hello,

I was not able to pass "Automatic Validation" for my indicator when I try to publish it at market place for MT5.  The report is not very helpful in this case.

test on EURUSD,H1 (netting) test49323 (EURUSD,H1) OnInit return code is INIT_FAILED cannot initialize indicator disconnected I started to cut my code to find problem line in code.

I started to cut my code to find problem line in code.

And problem is at function 

ChartWindowFind

It always returns -1;

This code always fails with validation:

Can you help me to pass validation?
