Hi

 I am new to MQL4 and have only been codding for about 1 Week.

First of thank you for all the advice, I have learnt a lot from reading postis in this forum.

I have been tying to code a EA and thus far I have managed to get it to a point where it uses custom indicators and based on the info it oppens a long or short possition with stoploss and take proffit.

How do I do the following:

Indicator crosses up though MA - long position is opened (Done)

Indicator crosses down though MA - long position is closed and short is oppened (Done)

After indicator crosses and opens long then take profit is triggered (Done) - this is where I need help once the take profit is triggered how do I tell it not to open another possion untill the indicators have  crossed down again. 

 

I hope I have explained myself propperly.

 

Thanks

Check for a change in signal, not a signal.
static bool isUp;
bool wasUp = isUp;
isUp = indicator1 > indicator2;
if(wasUp != isUp){ // NEW cross.

Usually, these type of EAs are coded to only work on closed bars. That is because there can be many crosses during the life of a single bar.

For a buy, check that Close[1] is above the MA & Close[2] is below the MA

Opposite for a Sell

Hi WHRoeder

Sorry, I just cant seem to figure out how or where to implement the code.

Here is the code in my EA that opens orders.

// BUY/SELL 
   if (C_Current>=T_Current)
     {
      Opn_B=true;                               // Criterion for opening Buy
      Cls_S=true;                               // Criterion for closing Sell
      Opn_S=false;                               
      Cls_B=false;
                   
     }
   if (C_Current<=T_Current)
     {
      Opn_S=true;                               // Criterion for opening Sell
      Cls_B=true;                               // Criterion for closing Buy
      Opn_B=false;                               
      Cls_S=false;
       
     }


// Open Position

 if (Opn_B==true && Total==0 )           //BUY
     {
     
         RefreshRates();   
         SL=Bid-New_Stop(StopLoss)*Point;     // Calculating SL of opened
         TP=Bid+New_Stop(TakeProfit)*Point;   // Calculating TP of opened
         Alert("Attempt to open Buy. Waiting for response..");
         Ticket=OrderSend(Symbol(),OP_BUY,Lots,Ask,2,SL,TP,"Order",Magic);//Opening Buy
         if (Ticket < 0)                        // Success :)
           {
            Alert ("Opened oredr Buy ",Ticket);
                                         // Exit start()
           }
         else
            Print("OrderSend placed successfully");

      }
      
if (Opn_S==true && Total==0)             //SELL
     {
     
         RefreshRates();                        // Refresh rates
         SL=Ask+New_Stop(StopLoss)*Point;     // Calculating SL of opened
         TP=Ask-New_Stop(TakeProfit)*Point;   // Calculating TP of opened
         Alert("Attempt to open Sell. Waiting for response..");
         Ticket=OrderSend(Symbol(),OP_SELL,Lots,Bid,2,SL,TP,"Order",Magic);//Opening Sels
         
         if (Ticket<0)                        // Success :)
           {
            Alert ("Opened order Sell ",Ticket);
                                      // Exit start()
           }
         else
            Print("OrderSend placed successfully");

      }

How do I need to change this to get this to work, also if I have made some errors please let me know.
