Normally when we are chasing a big move I take the last fractal (opposite) to stop... 3822 was that... which day was 3897 fractal formed ?

Alligator is a bit of a subjective indicator, its the way the three lines align and the angulation the price makes with the alligator... for bitcoin, I just use it to decide number of lots (1X, 2X, 3X etc.)... otherwise for forex and index its a good tool to decide the direction of the trade as well (buy/sell)...

Its all fractal geometry, glad you are liking it :-)
