Добавляем функцию lock (лок) в исходный код советника

extern double Risk = 5;
extern int lock_min_step = 30; //ограничение на минимальный шаг, чтобы не получилось каждый пипс новый лок
extern int lock_part = 2; //насколько частей будем дробить убыток который находится в рынке, если 2 то значит на 1/2
string lock_signalsymbol = "EURUSD";
static double lock_eqviti,lock_last, lock_lot;
static bool lock_flag,flagADX,old_uptrend;

2. Функцию start() переименовываем в start_main() и добавляем над ней:
int start(){
double AccountRisk = (AccountBalance()-AccountEquity())/AccountBalance()*100;
if (AccountRisk >Risk) lock_flag=true;
if(OrdersTotal()<1){lock_eqviti=AccountBalance();lock_last = Close[0];}
if(lock_flag) start_lock(); else start_main();
return(0);
}

3. В функцию init() добавляем
int init(){
init_lock();
return(0);
}

4. Ниже добавляем:
int init_lock(){
lock_eqviti=AccountBalance();
lock_lot = 0;
lock_last = Close[0];
flagADX=true;
old_uptrend=false;
signal();
lock_flag = false;
return(0);
}

void start_lock(){
int sig,step;
if(OrdersTotal()<1){init_lock();return(0);}
notakeprofit();
if (AccountEquity()>=lock_eqviti){CloseAllFirstProfit();init_lock();return(0);}
else{
sig=signal();
step =MathAbs(sig);
if (step<lock_min_step) return(0);
if (Ask>lock_last+(step*Point) && sig>0 ){
if (lock_lot==0)lock_lot=NormalizeLot(GetAmountLotFromOpenPos("", OP_SELL,-1)/lock_part);
RefreshRates();
OrderSend(Symbol(),OP_BUY,lock_lot,Ask,5,0,0,"lock",0,Blue);
lock_last = Ask;
}
if (Bid<lock_last-(step*Point) && sig<0){
if (lock_lot==0) lock_lot=NormalizeLot(GetAmountLotFromOpenPos("", OP_BUY,-1)/lock_part);
RefreshRates();
OrderSend(Symbol(),OP_SELL,lock_lot,Bid,5,0,0,"lock",0,Blue);
lock_last = Bid;
}
}
return;
}
