A favor for both of us!

Hello! I found a seemingly excellent open source code on this website: https://www.mql5.com/ru/articles/7777 (Let me know if you are unable to access this)

The file "griderKatMultiEA.mq5" is able to compile on MetaTrader 5. But when I try to backtesting, no trading happens. I guess the reason is the author publicized the strategy several years ago, when the MetaTrader 5 might be in a former version, incompatible to the latest version.

As you may have noticed from the website, this strategy is very likely to earn high profit. Thus handling its problem is not only favorable to me. It also benefits you!

I will reply to any application once I wake up again and see it, since I sleep irregularly in recent period. Thank you!

Please don't get confused about the $30 lower bound. My actual payment would be high if you could demonstrate to me that you have successfully fixed the code by running backtesting on some forexes successfully, before giving me the code. Specifically, the code's backtesting result graph should be similar to the picture on the website where it is downloaded.
