Howzit and welcome to the forum.
Most of the TRO's posts and indicators are too confusing and distracting. I suggest you stay with something simple.
The TTM Scalper looks for the SwingHigh (Swing High occurs when the Price of a bar is at least as high as the same Price on the preceding bar(s), and higher than the same Price on the bar(s) that follow it.) and goes back on the chart and paint in the signal of the Swing High point (eg., it repaints by going back in time). It does this with the same logic for the SwingLow.
AFAIK, there is no exact replica of the TTM Scalper for MT4 for free. The equivalent indicator in the MT4 platform could be the 3_level_zz_semafor-indicator.
zz stand for zigzag, which is an indicator that finds swing points that are distant by at least the percent or number of bars specified by the input.
Again, anything based on zigzag or swing logic will need to repaint or redrawn after the swings are established. The better indicators will tell you when the repaint actually occurred. The more deceptive indicator will just show you the final results and at a first glance appeared it nailed the top and the bottom when in fact it is an act of time traveling.
