About Kdj indicator buffer

[EA]

Hi,

I want to use kdj indicator which is like stochatic ossilator. In kdj, there are 3 buffers.

I wanted to use buffer 1, when it crosses 1 then buy signal will be opene. How can I make it?

I am trying "condition" and then my indicator -->> kdj . Then I selected the buffer. On the opposite side I selected value and numeric. But when I backtest the ea doesnt do anything .

Can you help me?

Ok, I found the error. The indicator also should be in the folders's of the mt4. It is not located in the Ea.
