Hello,
I can create the EA for you. I am the programmer for MetaTrader from 2004 year.
Please, describe in details your trading strategy. I can not accept project with unknown trading strategy.
About run EA on the renko-chart:
Your offline Renko-chart must support EAs. The last versions of indicators that create Renko-chart to support Eas, some last versions - does not support. The indicator should have parameter similar as EmulateOnlineChart=true/false and you should set there value "true".
Main things: it is not depend from EA that you attach to renko-chart, it is depend from indicator that you use for creating renko-chart.
You can go to my profile and see ~70 feedbacks about my programming jobs for MT4.
I support my programs even if project was completed. Usual I read mails as minimum
once per 24 hours. And usual I process a new request of employer in during 3 days.
Also, I can send you the example of my public EA "Assistant" that show my skill in programming for MT4. The EA "Assistant" does not open orders, it just manage existing orders that was opened by manual.
Sorry for my English.
Good Luck.
Serega Lykov.
