Drawdown protection

hello i do algorithmic trading i use several symbols at the same time i would like an ea to protect fairness.

i do grid trading and use martingale.

it needs to see which expert has opened which order

for example, when we reach 5% drawdown, I want him not to open any more trades on the other experts who haven't yet opened an order, but only on the symbol or symbols where there's a drawdown, so that he can continue to open orders if necessary.
