How to turn off "buy now" and turn on another "buy now"?

[Andrew b]

How to turn off "buy now" and turn on another "buy now"? I want to have 2 "buy now" blocks. 1 with fixed volume and another with martingale. I want to start with fixed volume and if 3 trades are in lose to turn of this block and start another one with martingale. I tried to use "Check consecutive losses/profit" and "turn on/off" blocks but didnt worked, i don't know how to connect them i think.

@l-andorrà I tried with this blocks and I succed to start 'martingale block' after 3 loses and to stop 'fixed volume block'. But once 'fixed volume block' is turned off, don't start again after a TP hit and i don't know why don't start again.
