Inflow/Outflow Index (IOI)

The Inflow/Outflow Index (IOI) is a high-sensitivity momentum oscillator designed to visualize the tug-of-war between aggressive buying and selling. Unlike a standard RSI (which only tracks price change) the IOI scales price action by actual traded volume, providing a clearer picture of where the "Smart Money" is moving.
- Buying Inflow: Occurs when the price closes higher than it opened, weighted by the volume of that period.
- Selling Outflow: Occurs when the price closes lower than it opened, weighted by volume.
These flows are then smoothed using an Exponential Moving Average (EMA) and processed through an RSI-style formula to create an oscillator that moves between 0 and 100.
How one reads this indicator:
The Midline (50): The "Control Point" where the tug of war is in a state of balance / indecision.
- Above 50 (Green By Default): Buyers are in command, and capital is flowing into the asset.
- Below 50 (Red By Default): Sellers are dominating, and capital is flowing out of the asset.
- Extreme Inflow (>80): Signal of intense buying pressure; the trend is strong but watch for exhaustion.
- Extreme Outflow (<20): Signal of heavy liquidation; potential for a "oversold" bounce.
- Divergences: If the price makes a new high but the IOI makes a lower high, it suggests the move lacks the "volume fuel" to continue, signaling a potential reversal.
Godspeed friends!
