With bullish wind in your sails, it's a little easier to "trust" some typical TICK divergences (highlighted). Selling (profit-taking) seemed prevalent throughout the day.
I believe LBR refers to the setup below as an "Anti" which shows itself as a small flag. In toddstrade™ nomenclature I refer to it as 1b-to-1a. The "trigger" would be the faster time frame fast line going green (in the scenario below the faster time frame was showing 2c-2d criteria so you could drill down further still and look for a 3d criteria on a faster time frame). The discretionary aspect of this approach arrises in making the decision to either wait until the bar closes or get in as price is breaking out.
As an aside, a picture perfect "First Cross" setup occurred on 4/23 (indicated with an up-arrow on that date) on this higher time frame ES chart (below, left). Also 1b-1a criteria except the slow line just came up through the zero-line.
