need help with adding a buy order and sell order when condition meets

[John Brown]

I've been trying to check my open trade if there is an open trade then dont trade , i only want one trade to be open, I also wanna create a buy order 

but it doesnt work it gives me i "2020.07.09 18:11:45.128 2020.01.03 17:36:15   CTrade::OrderSend: market buy 0.01 @EP sl: 3017.35 tp: 3023.35 [invalid volume]"

if (price > above) {

   

   

   if (runningmacdsignal > 0){

      

      if (price > runningfivesma) {

      

         Print ("goin to place a trade at" + Ask);

         trade.Buy(0.01,NULL,price,sl,pt,"WE BOUIGHT");

         

      }

      else {

      

      Print ("The price is not above the running fivesma");

      }

   }

   else {

   

      Print ("the macd is not bullish");

   }

}

else {



   Print ("the price is not above the 200day sma 15point");

}

}

What instrument (stock, futures, etc.) are you trying to buy? And are you able to buy a quantity of 0.01 of it?
