Repainting indicator

1. No mind readers here. How can we help when you don't provide any code?
2. You read the values of the CI using iCustom. Detailed explanation of iCustom - MQL4 forum
3. You can not read Hi/Lo of bar zero for other TF/pairs in the tester. Testing Features and Limits in MetaTrader 4 - MQL4 Articles

Hello WHRoeder, thank you for the articles. My only concern is about testing this strategy before to try to go to live trading with it.

I did not want to bother anybody to help me with the code, but I am getting confused.

I did some testing going through different timeframes at time and the indicator does repaints due the problem I mentioned before.

I got two questions now:

How can I really find a way to backtest any MTF strategy.

How can I develop an indicator that helps me to visual backtest this information.

Thank you guys, I hope I did not bother anybody with this topic.

I post it as job so somebody can help me to save a bit of time.

https://www.mql5.com/en/job/4505

This moment there is an error on JOBS MQL5 site so that noone can take part till that error 500 is repaired.

So you have to wait to get respons there....

Hello guys sorry. Again one of the developer of mql5 told me that is does not know how to accomplish this task.

Is there anybody that can help me if is possibly possible to write the indicator and after an EA that works with the SAR on three or timeframes using the 0 index ?

Thank you, Francesco.
