RSI of Other Sources

RSI of Other Sources is the definitive clean take on RSI of other sources: Wilder's formula, unchanged, pointed at whatever series you select. On-Balance Volume is the default; Volume, VWAP Distance, Momentum, Rate of Change, another symbol's close, or any custom plot can take its place. The derived line sits on the familiar 0-100 scale, colored by its side of 50 with a gradient fill, next to a muted Price RSI of the same length so the two reads compare at a glance.

How to Trade the RSI of Other Sources?

• Midline crosses: the derived RSI above 50 means bar-to-bar changes in the selected series are tilting positive — with OBV selected, that is volume flow expanding, not price rising.
• Derived vs Price RSI splits: when the two lines disagree, the price move lacks support from the selected series — the disagreement this tool exists to surface.
• Overbought / Oversold crossings: entries into and exits from the dashed threshold zones, remembering every source keeps its own extremes.

Six alerts cover both midline crosses plus entry and exit at each threshold.

RSI of Other Sources Settings

• Applied To (default On-Balance Volume): the series the RSI formula runs on.
• RSI Length (default 14): Wilder smoothing lookback, shared by the comparison line.
• Custom Source (default close): used by the Custom Source option and as the base for Momentum and Rate of Change.
• Momentum/ROC Length (default 10).
• Other Symbol (default empty, meaning the chart symbol).
• Input Smoothing (default None, length 14): optional SMA/EMA/WMA/RMA applied before gains and losses are measured.
• Overbought (default 70) / Oversold (default 30).
• Price RSI Comparison and Gradient Fill are on by default.

Frequently Asked Questions

Is RSI of Volume just the Money Flow Index?

No. The Money Flow Index bakes volume into a price-based calculation's gain and loss sums. This build runs untouched RSI arithmetic directly on the raw series you pick, so RSI of Volume asks whether participation itself is accelerating.

Should I keep 70/30 on a derived series?

Treat them as starting points. A cumulative input such as OBV can hold extreme readings far longer than closes do, while a choppier one may rarely reach them. Study the derived line over deep history and reset the thresholds from the range it actually occupies.

What does Input Smoothing change?

It averages the selected series before the gain/loss balance is measured, removing whipsaws at the cost of speed. That differs from smoothing the oscillator afterward — pre-smoothing changes which bar-to-bar changes the RSI ever sees.
