We call these moves Grinds and normally start during late Asia session. However saying that, it’s easy to see after the session is closed but hard to see till you have a trade in red pips. This is the reason I set all my GJ trades to hedge at 10 pips. The idea being to limit every drawdown only to 10 pips. Then I wait to have a second attempt to get the reversal. It’s rare for me to be wrong more than twice in a row so that’s just 20 pips I have to recover on a strong move. Let us know how your indicator goes.
