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.
