Oz.Fx,
just want to say your 4-hr version is very good, and seems to catch some good turning points.
So, good stuff there. 👍
Interestingly, you can see that your method coincides with narrowing of price action, which "might" presage reversals.
Either way, a newbie could do worse than follow your method on the 4-hrs, as long they understand WHY it works.
EDIT: to readers: YES I have done back-tests over the weekend. NO, I wont share them. Do your own work, it will help engender confidence if you decide to use this method.
