yes this is what's called "repainting"
on the left the curve changes direction before any sign of price reversal

I don't understand, I thought repainting was a totally different thing. I was backtesting it but the channel never repainted itself while testing, only draw a different shape compared to the one on the live chart. Actually the one on the left (live chart) respects the tops and bottoms of price better than the one on the offline chart. So if the channel behave like that it seems good for using with live trading strategies, the only problem is that you can't backtest it because it turns out different. Am I missing something?

repainting is basically reading the future and painting some signal in the present time with these datas. Of course it cannot work when you backtest the indicator, because it then has no idea of the future.
