- what is it it show parallel channel auto-matically
- how is possible (source is protected) it just use linreg function (built-in pine script function.) and find center line from 'learning_length' candle. also stdev between candle and center line. also max distance. and draw channel using center-line + stdev + fibonacci ratio + max distance.
until the channel get broken, it keep same channel. so this is not re-paint indicator. it is leading actually.
