Pretty sure everyone knows what a Linear Regression Channel is and how to use it, for those who don’t; Google it. Or, if the mods haven’t deleted them all, search for one on the many posts containing reference to same.
As a personal snippet to how I utilize them for exits, I look for failure of momentum outside the upper/lower bands. Normally they are wonderfully accurate. Yesterday, after the exit was given across all JPY pairs almost all went on to grab another 20 or so pips. More often than not they don’t leave much on the table, but I’m always happy to get out clean even when they do.
