No, I do not agree with you.
Solar Wind is a very accurate indicator end usually it does not repaint.
I use it every day with great success on 15min., 30min., 60min., end 4 hour charts. Just following the BUY or SELL on the 30min. end you will collect pips.
Of course en EA for this precious indicator will be perfect !
I attached 2 chart pictures, you can see that the indi repaints, i say most intensive !!!
The chart: M1 at 18:10 and 18:15
If the indi repaints in M1, it repaints in all TF, maybe in higher TF not so strong, maybe.
Funyoo had create an EA with SolarWind, the signals of SolarWind was horrible.
