Multiple trade entries on single buy or sell entry

[Gilson Bakiri]

Hi,

I wrote a mql5 ea code to buy to open on stochastic oversold and sell to open on stochastic overbought, at %K and %D crossover.  However when it hits the necessary requirements for entry the buy and sell are executed but multiple buys are triggered, or multiple sell are triggered and multiple tickets at the same time.  I intend to have only one entry, that is, one ticket at any one time. That is, to close an open position before an entry at the overbought and oversold areas.

My sample code for overbought is like this, for sell-to-open: [it seems by this code, multiple open ticket iteration happens. I intend to have only one ticket entry at a time]. Please assist. 

// SELL SIGNAL

  // if both values are above 80

   if (KValue2>80&&DValue2>80)

   // if the K value has crossed the D value from above

  if ((KValue1<DValue1)&&(KValue2>DValue2))

        {

       trade.PositionClose(_Symbol);  // close the existing position        

       trade.Sell(0.10,NULL,Bid,0,NULL); // and sell-to-open new position

       signal="sell";

 }

2. You are looking at a signal. Act on a change of signal.

3. Or, only process new candles.

   For a new bar test, Bars is unreliable (a refresh/reconnect can change number of bars on chart,) volume is unreliable (miss ticks,) Price is unreliable (duplicate prices and The == operand. - MQL4 programming forum.) Always use time.

   I disagree with making a new bar function, because it can only be called once per tick. A variable can be tested multiple times.

4. Or check for open order(s) before opening more.

So you can allow it to only open an order when

if(OrdersTotal() == 0)
   {
   // Do something...
   }
