# How to create Trailing Stoploss in Expert Advisor in MT5

### What is a Trailing Stop Loss ?

A trailing stop is a modification of a typical stop order that can be set at a defined percentage or dollar amount away from a security's current market price. For a long position, an investor places a trailing stop loss below the current market price. For a short position, an investor places the trailing stop above the current market price.

I have search online in almost every possible ways to find the code of trailing stop loss but I got nothing. So after making lots of effort and hard work I finally crack it. Now i am going to share with you all guys so that you also can use it. If you are reading this article that means you already knows how trailing works, so I am not going to explain its working.

I have created a trailing function in which I am calculating point and digit before using it because some times it doesn't work with JPY pairs, so I have calculate them separately and use variable later.

```double TrailingStop  = 250; // Setting Traling to be triger at 25 pips.

int OnInit()
{
return(INIT_SUCCEEDED);
}

void Trailing()
{
if(PositionGetInteger(POSITION_MAGIC) == 444444)//adding magic number, if you want you can delete this if you don't want to use magic number
{

for(int i=PositionsTotal()-1; i>=0; i--)
{
string symbol = PositionGetSymbol(i);
ulong PositionTicket = PositionGetTicket(i);

double POINT  =       SymbolInfoDouble(  symbol, SYMBOL_POINT  );
int    DIGIT  =       (int) SymbolInfoInteger( symbol, SYMBOL_DIGITS );

{
double Bid = NormalizeDouble(SymbolInfoDouble(symbol,SYMBOL_BID),DIGIT);

if(Bid-PositionGetDouble(POSITION_PRICE_OPEN) > NormalizeDouble(POINT * TrailingStop,DIGIT))
{
if(PositionGetDouble(POSITION_SL) < NormalizeDouble(Bid - POINT * TrailingStop,DIGIT))
{
}
}

}

{

if((PositionGetDouble(POSITION_PRICE_OPEN) - Ask) > NormalizeDouble( POINT * TrailingStop,DIGIT))
{
if((PositionGetDouble(POSITION_SL) > NormalizeDouble(Ask + POINT * TrailingStop,DIGIT)) || (PositionGetDouble(POSITION_SL)==0))
{
}
}

}
}

}

}```
