that's simillar indicator as one I use for EA Goodarrow(rev A), you can't test it, but works like charm in real time. Collors are switched, but it looks like same or simillar indy.
Arrow comes right at the change of candle, and is very accurate, doesn't repaint.
I'm posting goodarrow one, running ea on 30 min, result's are not bad. Sollar joy looks better than trendtma used in goodarrow ea. I've just started using good arrow ea with new indy, result's are not bad.
Maybe you can combine solar wind joy with goodarrow indy.
thx!
