I trade Live micro and on demo mini
I am trading overall 11 pairs and this is the problem I can't catch all CT because it is too much but when I see some I take it only one bad think about CT is RR it is only 1:1 max 1:1.5 but the winrate is big like I say previous.
and how many trades per week? sometimes one sometimes four-six. When I see CT I take it but I want code some indicator for help me to be more accurate
