help with this EA code please!

Hello, I have a crossover ea of 2 EMAs, but what I need is that when the 4 period ema crosses the 100 ema the command 50pips will open after having crossed, currently the robot that I have opens it immediately, I made some modifications using a double variable called Preciobuy and another PrecioSell that saves the price so that when the bid is above that value, it will mount the operation but it doesn't work for me, I don't know what to do .. please help.

I will leave my code so that you can see it and you can help me:

• First ... let take a look sample code on ur open buy rule :
  
  --> iMA(NULL,0,5,0,MODE_EMA,PRICE_CLOSE,0)>iMA(NULL,0,100,0,MODE_EMA,PRICE_CLOSE,0)
  above code mean EMA4 > EMA100 not EMA4 crossing EMA100
  
  
  
• Second.. U need EMA4 and EMA100 at previous candle to determine its cross or not :
  
  EMAbuyCrossValue -->
  iMA(NULL,0,5,0,MODE_EMA,PRICE_CLOSE,0)>iMA(NULL,0,100,0,MODE_EMA,PRICE_CLOSE,0) && iMA(NULL,0,5,0,MODE_EMA,PRICE_CLOSE,1)<=iMA(NULL,0,100,0,MODE_EMA,PRICE_CLOSE,1)
  
  EMAsellCrossValue -->
  iMA(NULL,0,5,0,MODE_EMA,PRICE_CLOSE,0)<iMA(NULL,0,100,0,MODE_EMA,PRICE_CLOSE,0) && iMA(NULL,0,5,0,MODE_EMA,PRICE_CLOSE,1)>=iMA(NULL,0,100,0,MODE_EMA,PRICE_CLOSE,1)
  
  
  
• Second.. U dont need preciobuy and preciosell after get EMA Buy cross value
  
  trigger buy logic --> if (Ask > EMAbuyCrossValue+50) then BUY
  
  trigger sell logic --> if (Bid < EMAbuyCrossValue-50) then SELL
