How to code? - Page 87

Does anyone know how to code so that when you call an indicator in an EA it automatically attaches the called indicator to the chart your EA is attached to? This way it would visually be in the exact same time as what is being read by your EA.

Thanks.

You must attach both EA and indicator unless the indy is coded inside the EA.

how to code this:
I need to extract some info from last closed trade,
and after use some info from this last trade

I threw together an adjust trailing stop function for EAs, can someone check it out?

Code:

//+-----------------------------------------------------+
//|           adjust trailing stop                      |
//+-----------------------------------------------------+
void AdjustTrailingStop()
{
  int orders = OrdersTotal();
  for(int j=orders-1;j>=0;j--)
  {
    OrderSelect(j, SELECT_BY_POS);
    int type = OrderType();
    //-- Adjust trailing stop for BUYs
    if (type == OP_BUY && OrderSymbol()==Symbol() && (OrderMagicNumber() == MagicNumber))
    {
      if (Ask-TrailingStop*Point > OrderOpenPrice() && Ask-TrailingStop*Point > OrderStopLoss())
        {
          OrderModify(OrderTicket(),OrderOpenPrice(),Ask-TrailingStop*Point,OrderTakeProfit(),0);
        }  
    }
    //-- Adjust trailing stop for SELLs
    if (type == OP_SELL && OrderSymbol()==Symbol() && (OrderMagicNumber() == MagicNumber))
    {  
      if (Bid+TrailingStop*Point < OrderOpenPrice() && Bid+TrailingStop*Point < OrderStopLoss())
        {
          OrderModify(OrderTicket(),OrderOpenPrice(),Bid+TrailingStop*Point,OrderTakeProfit(),0);
        } 
    }
  }
}

thank you.

Please, try this:

PHP Code:


			
Comment(DoubleToStr(1/2, 1));

The second argument of the function DoubleToStr() is the number of digits after the decimal point.

It's easy to scan the history and check OrderCloseTime() :

PHP Code:


			
datetime LastCloseTime;

bool LastTradeIsProfit;

for(int i = 0; i > OrderHistoryTotal(), i ++)

{

   OrderSelect(i, SELECT_BY_POS, MODE_HISTORY);

   if(OrderMagicNumber() != Magic) continue;

   if(OrderCloseTime() > LastCloseTime) 

   {

      LastCloseTime = OrderCloseTime();

      LastTradeIsProfit  = (OrderProfit() > 0);

   } 

}

thank you for edite expert
can you change this ea using my idea

from my idea after opening two orders we explain this info
1- all orders have fix stop loss same 10pip
2-if the first order going to profit opening 2* same this order but tp=fist order tp-fix sl
3- traling sl to second order opening place

exampel:
eur/usd
on the first price is : 1.5200
1-opening two orders ( buy@ 1.5200 0.1 lot size sl=10 tp 50 & sell@1.5200 0.1 lot size sl=10 tp=50)
price go to 15210
2-at this time (my sell order will be close & will opening second buy order 0.2 lot size by sl=10 tp=40 and fist order sl traling to 1.5210 )
price go to 1.5220
3-at this time (opening buy order 0.4 lot size by sl=10 tp=30 and two befor orders sl traling to 1.5220)
4-.....
5....
if the price going to 1.5250 all orders will be close by 560$
but at this time our orders sl we only lossing 60$
this method have very best risk
