This channel is based on Linear regression by its % difference from the price the high and the low are determine by the % from the close price . For the best fit you need to put the TF on the same min of the graph. I put the channel to be 3 % above and bellow the price .by the same way you can add to the script more % line to make it better this is good indicator for filtering (if you want your signal to be above or bellow the % channel) or if you want to enter at certain price and exit by the regular TV alerts so it more easy where your target for long or short exist
