What this script says

Momentum Composite is an indicator drawn in its own pane.

You can change one input: `trix_length` (default 18).

It calculates `trix_line` as the TRIX (source the close, length `trix_length`), `volume_flow` as the volume oscillator (fast 5, slow 20), `mfi_line` as the money flow index (length 14), `composite` as (100 × `trix_line` plus `volume_flow` divided by 10 plus (`mfi_line` minus 50) divided by 50) divided by 3 and `bullish` as whether `composite` is above 0 and `composite` is above the previous bar's `composite`. It shares `composite` and `bullish` with scripts that use it.

On the chart, it plots `composite` as `composite_line` and draws a horizontal line at 0.
