Before I start implementing my own it is worth to ask - is there any cron - like module for MT4/MT5 that would serve as a time check for EA/Indicator?
For example: I would like to check something once every hour, 15 minutes etc. inside onTick()
I do not want to use timer https://www.mql5.com/en/docs/eventfunctions/eventsettimer but rather:
1. Check time
2. Execute action every 15 minutes in an hour when first tick arrives eg. 10:00 10:15 10:30 10:45 every day monday-friday
Forget it, I found a partial solution I need at codebase.
