Here's the code to call your EA's last trade price:

This can be useful for limiting your Martingale orders to lastOrderPrice +/- something... like 50 pips for example, in your trading conditions. Obviously, this is for SB Pro users.

First, declare 3 new variables in your global variables like so:

Code:

 double  lastOrderPrice;
 double  mPipBuffer;
 extern int MartingalePips=50;

Note that extern creates a new adjustable EA input!

Then, put the following code under:
int start()

Code:

for (int i=OrdersTotal()-1; i>=0; i--) 
  {
    if ( OrderSelect(i,SELECT_BY_POS, MODE_TRADES) )
      {
        if (   OrderType() == ( OP_SELL || OP_BUY )  
           &&  OrderSymbol() == Symbol()  
           &&  OrderMagicNumber() == ( MagicNumberShort || MagicNumberLong ) )

               lastOrderPrice = OrderOpenPrice();
      }
  }

mPipBuffer = MartingalePips * PipMultiplier * Point;

Of course, the last step is adding && iClose(Symbol(),0,0)>=lastOrderPrice+mPipBuffer to your BUY condition for example. I trust the admins will tell me if I have it wrong. Hopefully this will inspire others to post their hardcode mod's as well.

Thanks. Great code.
We are working on a function that does the same but uses the pair as an input so you can get the last traded price per pair.

For code like this:
for (int i=OrdersTotal()-1; i>=0; i--)

I like to write it like this:
int variablename=OrdersTotal();
for (int i=variablename-1; i>=0; i--)

Very nice. I'll be doing backflips when the new version comes out.

Let's keep this train rolling. For any risk junkies out there, put this in your globals:

Code:

extern bool    whileOpen = true;    // use martingale while positions are open--can stack floating P/L--Created by User

And this in with the afterLoss and afterWin conditions:

Code:

      if (whileOpen) {
         if ((CalculateOpenPositions(Symbol(),OP_SELL||OP_BUY,MagicNumberShort||MagicNumberLong))<MaxNumberofPositions) {
            lot=NormalizeDouble(OrderLots()*MartingaleMultiplier,AccDigits);
            }
         }

It's designed to stack open trades--longs and shorts. Note that the open trades can be losing or winning (P/L is floating), so build your // trading conditions using +/-MartingalePips as appropriate. To separate long stacking from short stacking, create 2 new variables and break apart the CalculateOpenPositions string to build 2 new conditions.
