i need help with my trailing stop loss, it does trail but doesn't stop loss

[Sechene.9604]

guys I made an EA that buys when a candle closes bullish, now my problem is the trailing stop loss, for example after a buy order is performed and the chart move in my direction the trailing stop does trail but when the chart changes direction the TSL doesn't close the locked profit, so please help me find the problem 

here is the code

//Create an instance of CTrade
#include<Trade\Trade.mqh>
CTrade trade;


void OnTick()
  {

          
double Ask=NormalizeDouble(SymbolInfoDouble(_Symbol,SYMBOL_ASK),_Digits);

if (PositionsTotal()==0)

trade.Buy(0.30,NULL,Ask,(Ask-1000*_Point),0,NULL);

CheckTrailingStop(Ask);
}

void CheckTrailingStop(double Ask)

{
double SL=NormalizeDouble(Ask-
150*_Point,_Digits);

for(int i=PositionsTotal()-1; i>=0; i--)
{

string symbol=PositionGetSymbol(i);
if (_Symbol==symbol)
{

ulong PositionTicket=PositionGetInteger(POSITION_TICKET);

double CurrentStopLoss=PositionGetDouble(POSITION_SL);

if (CurrentStopLoss<SL)
{
trade.PositionModify(PositionTicket,(CurrentStopLoss+10*_Point),0);
}
}
}
}

How many times have you been told to use the code button (Alt + S) when pasting code?
