DislikedI think he means if you put a buy order and price moves against you downward, you put another buy order and keep doing that in hopes it comes back up.Ignored
This is the exactly same like martingale as you explain.
But in this strategy if I put buy order and price will move against me downwards then I will not put another buy order actually. In that case I will close the buy order and will enter into sell order accordingly.
I hope it is understandable......
