I've been paper trading this TV indi for months now and it seems to be quite accurate (60-70% win rate) - if anyone can code it from Pine to MT4 and add alerts it looks like it has a lot of potential. Someone actually already coded a similar MT4 indicator but is quite basic and not user friendly. The TV version also had a lot of other cool options.

TV indi - DIvergence for many indicators V4
