The full extent of the move is 83+ pips and to the 50% PRZ it's 41+ pips. For my standards, both are great amounts, but I'm doing my due diligence at keeping my greed in check. However, I would "eat chunks" out of the move by scaling in on price. If it don't reach the zone and it continues to tank then I'll adjust my approach. I would wait for a B.A.R to execute from the swing low of the move. We shall see.
