Overview
Intraday Momentum Index (IMI) measures gains when the close is higher than the open and losses when the close is lower than the open over a set lookback period. Computed using a circular buffer for efficiency, the indicator plots momentum as a line in a separate pane.
- Intraday gain and loss comparison
- Circular buffer for O(1) per-bar computation
- Customizable calculation period
- Separate pane oscillator plot
