It's a GRID. what MT5 does is join the new positions all in one, but in reality when the market goes against the position the trader open new positions bigger than the previous ones as any regular grid.
In order to see this, it's need to open the MT5 platform, go to the history, click to the right button of the mouse and choose to DEALS instead of ORDERS.
Grids sooner or later burn the account. For now it has doubled the DD from 21% to 42% and still the positions opened.
