Martingale extra protection

SCALPPING JA 100 1-500 EURUSD .set

Hi guys, I wanna suggest a way to administrated the capital like "this example":

1 - total capital in account: 300

2 - the expert uses only a pre determinated value (N) in percents (N%) to initiate negotiations: this example 33% = 100

3 - the last 67% will be used only in martingale "protection"

4 - when martingale finished the protection, the expert uses the pre determinated 33% to start a new deal. And so on....

5 - we will have an extra protection in case of losses.
