The Expert Advisor manages all open positions in the terminal (on all symbols and with all magic numbers). If the total profit has not reached “minimum_profit“, the EA waits.
If the total profit has reached “minimum_profit“, the EA sets a percent of profit drawdown and enables tracking.
The “percent_of_profit” parameter is specified in percent. For example, “minimum_profit“ = 1000 and “percent_of_profit” 20. The total profit of all open positions has reached 1000. If the profit falls to 800 (1000 – 20%), positions will be closed. If the profit continues to grow, for example up to 2000, the allowable drawdown will be equal to 400 (2000 – 20%). That is, all positions will be closed with the total profit of 1600. There is no fixed drawdown limit, as I do not find it useful to use absolute values.
In theory, it is possible to set percentage = 0. It will function as a total Take Profit. It is possible to set percentage = 100, it will function as breakeven (do not forget, as some orders are being closed, others may become losing).
Attention! The Expert Advisor works with the 3-second interval:
voidOnTick()
{
//--- allow work every three secondsstaticdatetime prev_time=0;
datetime time_current=TimeCurrent();
if(time_current-prev_time<3)return;
prev_time=time_current;
//---
