Hello!

I need help in using indicator "Heiken-Ashi" in my expert advisor.

I would like to get value of haOpen, haHigh, haLow, haClose to my calculations but I can not refer to them. I would like to use moment of change color of bars which shows direction of market. How to get signal of change direction from that indicator "Heiken-Ahi" and use it in expert advisor?
