Thank you so much for your replies.

I couldnt find the indi via search fonction because it is spelled incorrectly.

Standar error bands.mq4 but should be : standarD error bands.mq4

Ive been toying around with the channel and the bands this morning , and to me the se bands are far superior on nasdaq and dax and stocks in general to extract profit and get reentries compared to g channel. I havent looked on commodities and forex yet , but my guess would be that it doesnt really work on forex while its minblowing on commodities.

Both are on period 145 on this renko graph of yesterdays session. Granted it was a crazy session and these settings work only with huge trends.
G channel : SE bands : this is a test on ranging markets : but it gets better if you use period = 45 and this is the crazy market in the first pictures with settings 45 many more charts to come.

i have attached template for easy setup if you want to test
