How to add one green/red bar confirmation into an EA?

New comment
 

Hello Guys,

I have created a simple RSI based EA. I would like to add one bar confirmation in it.

For example, lets say that if EA would take a "BUY" trade when RSI is 60.....then instead of taking a trade right away.......EA should wait for one more candle and if it is also green then only EA should take a "BUY" trade. (And vice-versa for Short trades)

I am attaching my EA code below. It would be great if anyone could explain me how to do it or redirect me to some tutorial link.

thanks :)

First, make a change to your code:

1.strings 

      CTrade trade;
      trade.SetExpertMagicNumber(MagicNumber);

need to be placed in the "header" of the expert

 input double DecreaseFactor     =
   30 ;       // Descrease factor
//---
CTrade trade;
trade.SetExpertMagicNumber(MagicNumber);


2. Correct the 'iRSIMQL4' function - in MQL5, the indicator handle must be created once in OnInit. Better yet, do not use MQL4 words in the MQL5 code - otherwise you will constantly make mistakes.
