*** I recommend using Hollow Candlesticks b/c it allows you to see the exact price action. No matter what the color of the bar is if it is a hollow bar the the close was greater than the open (typical Green Candlestick), and if it is a solid bar the close was less than the open(Typical Red Candlestick).
There are many ways to use this study. This example uses Chuck Hughes 50 and 100 EMA. Note a pullback to the Upper 50 EMA then waiting for a confirming change in the Heikin-Ashi Bar Color = Gives Great Entry. This is assuming with Chuck’s methodology That Stocks are Trending Up and ideally reaching new 52 Week Highs.
