Modify to an Existing EA

I need a coder to make this rule for me, so I can integrate it in my EA.

The strategy  is to count from last Orders open price,

if price goes up X-pips, it opens a BUY (POS1), then  if price goes down X-pips,  it opens a SELL (POS2).

So far so good.

But then if the price goes up again X-Pips, it would open again at the same price as the existing opened BUY, but we want it to go further up from here the X-Pips before it  is allowed to open a BUY (POS3).
If the existing Opened BUY is more than 2 positions away, it is allowed to open the BUY at the same price.

//=========== Code

  int tick=GetLastPositionTicket();   

  if(OrderSelect(tick,SELECT_BY_TICKET) && GVGet("Stopped")==0 && GVGet("Start")==1)

    {

      if((OrderOpenPrice()-Bid)/(Point*P)>Distance_Down)sell=true;     

      if((Ask-OrderOpenPrice())/(Point*P)>Distance_Up)buy=true;

    }
