I have notified support about this issue, but have not received response, so i'm posting this here.
The issue is that under certain settings the fama line of the MAMA2 indicator starts to behave in a strange manner (see picture, violet line)
The issue is present in Jforex 3 and 4. The issue appears when i decrease "slow limit" setting under 0.06 or/and "fast limit" under 0.2.
