I've seen dozens of TTM's videos.
The strategy is not to scalp long at tick extremes,,,,the strategy is to fade 1000 tick readings (or established tick highs for the day) on sideways days and when the trin is sideways. The strategy is to go long on tick hooks when the trend is up and when ticks are near the low range, and vice versa for shorting the tick high readings.
That video was made by Hubert, not John Carter. Most the video's you see with training are by Hubert.
