Definition

Volume-weighted RSI: money flow direction over N bars on a 0-100 scale. Above 80 is overbought, below 20 oversold. Requires volume data.

Parameters

Asset, Lookback period (14)

Output range: 0 to 100

Example condition

text
`MFI(AAPL, 14) > 80` (Buying climax)

Usage notes

MFI divergences (price makes a new high, MFI doesn't) carry more weight than RSI divergences because volume confirms.

Use in a strategy

Add this indicator to a strategy condition, choose its supported parameters and compare the output with the threshold required by your rule. Preserve the same interval and lookback when comparing backtests.

After saving the condition, inspect its asset, interval, lookback and comparison operator against the parameters above. If no trades occur, check whether the condition ever became true and whether the requested input data exists for that period. A missing input is not a zero-valued signal. An indicator produces an input to a rule. It does not establish future returns, and data availability can differ across assets and periods.
