Martingala risk management

I need some functions for risk management. When ever a sell signal or buy signal become true I need a function that open an order with out SL and keep it open until it hit 1% account balance profit, if the position il still open and another signal in the opposite verse become true it close the position and open the new one with same logic. If the first position is in drawdown the bot will wait a new signal in the opposite verse and will open a new position in manner to recover from the drawdown position and gain 0,5% of account balance profit. It repeat the same thing also for the 3 order. At the 4 order if the sum of position is still drawdown the bot will try to open new positions always waiting a opposite signal and will try to close the positions in manner to recover from all losses and bring back the account balance where it started when it opened the first order of this loop
