This is an updated Tuesday Holiday Model (for Tuesdays following a three day weekend). This model averages in the most recent holiday data from Juneteenth (recognized June 20). The drops tend to fall at the exact algo sell zones - 10:30 AM, but the end of day drop tends to come earlier at 3:10.
Note that the chop zones on Tuesdays are typically very flat, and very severe eating away any profits you may be attempting to scalp. Chop Zones are typically from 1240 to 205 historically, but be mindful of the dangerous Tuesday chop, and use a momentum indicator to spot chops in case this zone shifts.
Happy Trading!
