Scripts: Exposure

Automated-Trading 2011.05.16 09:14
This script reads all opened position and calculates their exposure for each currency. It's useful if there are many positions.

Hi, this script does not seem to work.
I place it on the chart and it immediately removes it..and then under the Experts tab it says
"2019.08.14 19:19:31.762 exposure (GBPUSD,H2) array out of range in 'exposure.mq5' (63,34)"
Errors, bugs, questions array out of range Can't print text to

Not compatible with MT5 platform

I have found this one today. Someone converted it to Mt5. Thanks who made it.
Its working on Mt5. And I am modifying it . I would add when finished
Script : iExposure MT5.mq5
