Many Thanks Onyx. I will try on it Thanks.

Also my current EA open new order on every candle. How can i open a new order when my previous trade hit TP or SL?

int err=0;
double price=Bid, sl=0, tp=0;
if(type == OP_BUY)
price =Ask;
//----
int ticket = OrderSend(Symbol(),type,LotSize,price,Slippage,0,0,"Trade",MagicNumber,0,Magenta);
if(ticket>0){
if(OrderSelect(ticket,SELECT_BY_TICKET)){

if (OrderType()==OP_SELL)
{
sl = OrderOpenPrice()+(StopLoss*pips);
tp = OrderOpenPrice()-(TakeProfit*pips);
}
else if(OrderType()==OP_BUY){
sl = OrderOpenPrice()-(StopLoss*pips);
tp = OrderOpenPrice()+(TakeProfit*pips);
}
if(!OrderModify(ticket,price,sl,tp,0,Magenta)) {
err = GetLastError();
Print("Encountered an error during modification!"+(string)err+" "+ErrorDescription(err) );
}
}
