Based on lots of indi tested. The only indi that is non-repaint is an arrow that appear only after the current candle closed.
The arrow will remain there, but never will be the best signal. As for high timeframe, only can confirm the direction after few candle passed,
which we usually assumed our missed pips...if you agree. That's why we always look for the earliest and perfect signal and non-repaint indicator.
And all will be back to SnR, TL, Breakout.
