adding ma crosses to activate only longs/shorts?

[[Deleted]]

G'day again. I'm wondering if someone could kindly add an MA cross to the following code:

extern int TakeProfit = 155;
extern int TrailingStop = 55;
extern int StopLoss = 55;
extern double Lots = 1;
extern int magicnumber = 777;
extern bool PolLots = true;
extern int MaxOrders = 12;


int prevtime;
//+------------------------------------------------------------------+
//| expert initialization function |
//+------------------------------------------------------------------+
int init()
{
//----

//----
return(0);
}
//+------------------------------------------------------------------+
//| expert deinitialization function |
//+------------------------------------------------------------------+
int deinit()
{
//----

//----
return(0);
}
//+------------------------------------------------------------------+
//| expert start function |
//+------------------------------------------------------------------+
int start()
{
//----


int i=0;
int total = OrdersTotal();
for(i = 0; i <= total; i++)
{
if(TrailingStop>0)
{
OrderSelect(i, SELECT_BY_POS, MODE_TRADES);
if(OrderMagicNumber() == magicnumber)
{
TrailingStairs(OrderTicket(),TrailingStop);
}
}
}

bool BuyOp=false;
bool SellOp=false;

if (High[0]>High[1]&&High[1]>High[2]&&High[2]>High[3]&&Open[0]>Open[1]&&Open[1]>Open[2]&&Open[2]>Open[3]) BuyOp=true;
if (High[0]<High[1]&&High[1]<High[2]&&High[2]<High[3]&&Open[0]<Open[1]&&Open[1]<Open[2]&&Open[2]<Open[3]) SellOp=true;

if(Time[0] == prevtime)
return(0);
prevtime = Time[0];
if(!IsTradeAllowed())
{
prevtime = Time[1];
return(0);
}


if (total < MaxOrders || MaxOrders == 0)
{
if(BuyOp)
{
if (StopLoss!=0)
{
OrderSend(Symbol(),OP_BUY,Lots,Ask,3,Bid-(StopLoss*Point),Ask+(TakeProfit*Point),"OpenTiks_Buy",magicnumber,0,Green);
}
else
{
OrderSend(Symbol(),OP_BUY,Lots,Ask,3,0,Ask+(TakeProfit*Point),"OpenTiks_Buy",magicnumber,0,Green);
}
}
if(SellOp)
{
if (StopLoss!=0)
{
OrderSend(Symbol(),OP_SELL,Lots,Bid,3,Ask+(StopLoss*Point),Bid-(TakeProfit*Point),"OpenTiks_Sell",magicnumber,0,Red);
}
else
{
OrderSend(Symbol(),OP_SELL,Lots,Bid,3,0,Bid-(TakeProfit*Point),"OpenTiks_Sell",magicnumber,0,Red);
}
}
{

}
}

//----
return(0);
}
//+------------------------------------------------------------------+
void TrailingStairs(int ticket,int trldistance)
{
int Spred=Ask - Bid;
if (OrderType()==OP_BUY)
{
if((Bid-OrderOpenPrice())>(Point*trldistance))
{
if(OrderStopLoss()<Bid-Point*trldistance || (OrderStopLoss()==0))
{
OrderModify(ticket,OrderOpenPrice(),Bid-Point*trldistance,OrderTakeProfit(),0,Green);
if (PolLots)
if (NormalizeDouble(OrderLots()/2,2)>MarketInfo(Symbol(), MODE_MINLOT))
{
OrderClose(ticket,NormalizeDouble(OrderLots()/2,2),Ask,3,Green);
}
else
{
OrderClose(ticket,OrderLots(),Ask,3,Green);
}
}
}
}
else
{
if((OrderOpenPrice()-Ask)>(Point*trldistance))
{
if((OrderStopLoss()>(Ask+Point*trldistance)) || (OrderStopLoss()==0))
{
OrderModify(OrderTicket(),OrderOpenPrice(),Ask+Point*trldistance,OrderTakeProfit(),0,Red);
if (PolLots)
if (NormalizeDouble(OrderLots()/2,2)>MarketInfo(Symbol(), MODE_MINLOT))
{
OrderClose(ticket,NormalizeDouble(OrderLots()/2,2),Bid,3,Green);
}
else
{
OrderClose(ticket,OrderLots(),Bid,3,Green);
}
}
}
}

}

Say a 200ema over 75, if it crosses to the long side then only long signals are activated, and vice versa..
