thanks for replying. playing with the tools located here https://greenwichmeantime.com/time-zone/gmt-plus-3/ , i can safely confirm that GMT +3 is GMT 00:00 (NY Closing), London starts on 07:00 and NY starts on 12:00 and Tokyo starts on 23:00.
And The EA start trading time will be on on 07:00 and 12:00... right?

still on the right timeframe of the intended gave the best result
