A little help with EA code using icustom please

Hi all,

I am trying to learn how to programme my own expert advisor, i am sure you will all be shocked at how simple this code is but I am learning so please help me and point out where I am going wrong.

I have an indicator that I use, super_signals_v2_Alert.mq4, this paints green or red buy and sell signals and then sound an alert. When a green signal is painted I would like to open a long market order at the open of the next bar.

When a red signal is painted I would like to open a shoprt market entry at the open of the next bar.

If a long position is open and anotherr signal is painted in the same direction, it is ignored, only 1 trade open in any direction at any time.

If an opposing signal sounds then this closes the trade. I would like to have an option to have the EA always in the market so reverse when an opposing signal is triggered.

I have been trying to get this right but I am having no luck...

Here is what I have so far but I am not sure if the condition to open and close is correct as per the indicator as it doesnt open trades when the indicator alarms, it only buys and opens multiple trades in the same direction.

#include <stdlib.mqh>

extern double downtrend;// downtrend=iCustom(NULL,0,"super_signals_v2_alert",1,0); ???
extern double uptrend; // uptrend=iCustom(NULL,0,"super_signals_v2_alert",0,0); ???
extern int dist2=21;
extern int SignalBar=1;
input double lots=3;
input double TakeProfit=550;
int OpenOrders=0, cnt=0;

int start()

{

int downtrend = iHighest(NULL,0,MODE_HIGH,dist2,SignalBar-dist2/2);
int uptrend = iLowest(NULL,0,MODE_LOW,dist2,SignalBar-dist2/2);


if(downtrend && OpenOrders<1)
{
bool ticket=OrderSend(Symbol(),OP_SELL,lots,Bid,3,0,Bid+TakeProfit*Point,NULL,0,0,clrRed);
}
else if(uptrend && OpenOrders<1)
{
ticket=OrderSend(Symbol(),OP_BUY,lots,Ask,3,0,Ask+TakeProfit*Point,NULL,0,0,clrGreen);


}
}



Can someone please help me out here, it would be greatly appreciated.

Thanks
