The inputs are raw and super basic. At its core its really just 3 EMAs that you can customize the source and length. The averages and shadowing change color based on if they are either rising or falling.
default values are 5, 9, and 21 on open as source.
Bar color is dictated by the bar close over or under the 5 and 9 .
This is suitable for use on HA candle.
Also newly updated are alert functions to alert up or down crosses. Alerts are dynamic to give reference in the alert message to the timeframe the alert occurred and the closing price at the alert time
