Volume-weighted closing range of each bar. Closing range is (high - close) relative to the length of the wick (high - low). A close at the top of the wick would be 100%, middle 50%, bottom 0%. This is then multiplied by volume to weight towards high volume bars.
A moving average is applied to visualize trend in volume-weighted closing range over time.
Options include changing the threshold of bullish closes. The default is 50%, but you can view a close above 40% as a bullish .
How to use:
Columns indicate per-bar closing range, and can be used as either a buying-selling pressure indicator, or as an overreaction detector (eg, bars that are abnormally big can be used to start a fading/contrarian trade next bars). Green means the bar closed in the upper range, red in the lower range.
The cloud is the moving average over several bars (by default using EMA). This tends to represent sentiment over a period of time, and hence trend/momentum. Can be used in any timescale, even on weekly, then this represents the market cycles.
