Hello and thank you for this great script.
I have one question...
Does the current bar can change color during it's period?
Do we need to wait until the close of a bar to know it's final color?

@totoro3333, you should make your decion when the candle has closed

for what time frame?

Hi Chris, how does this work?

Hey mate
can we apply this in the strategy tester to see how it performs on the daily chart for fx pairs over the years?

how do i use this script i am new here

Hello Chris,
First off.. TV (and us) are fortunate to have guys like you around here.. :)

Entering and exiting trades based on HA alone is difficult as it doesn't show the actual price bars. This script hugely resolves that issue.

1. Smoothing of EMA that is displayed on the chart
2. Detect additionally that there are no down wicks (up wicks for short) on the HA bars.

Makes it even more effective!

Hello this is a great indicator!One question though ...I am new on this and i have tried out to create an alert when colours turn from red to green and the opposite.
Can it be done?
