Hermēs DocumentationSix Checks for Conflicting Data
Reconcile symbol, expiration, measurement, timing and perspective before interpreting conflicting panels.
Positive GEX and negative Net Flow are not necessarily a contradiction. One describes exposure under a particular model; the other describes trades during a selected period.
Open the relevant panels
Use HuntingFlow, GEX Data and the institutional data windows. Keep the settings with your screenshots.
| Check | Question | Action |
|---|---|---|
| Symbol and axis | SPX, SPY or ES_SPX? | Align the price axes first |
| Expirations | Nearest, next, aggregate or a specific date? | Compare matching scopes; labels need not mean calendar days |
| Measurement | OI-weighted, volume-weighted, classified flow or premium? | Keep names separate; do not compare raw magnitudes |
| Time form | Snapshot, session cumulative or rate of change? | Positive cumulative flow can coexist with a negative recent rate |
| Data time | Same session and replay instant? | Mark unverified timestamps as unresolved |
| Perspective and unit | Customer or dealer; money, contracts or Greek-weighted values? | Do not add values with unverified units or signs |
Chart heat traces, distributions and sub-panes may use different expiration settings. See Basis and the indicator dock.
Example
A positive session cumulative flow, weakening recent flow and positive aggregate GEX can all coexist. They describe past accumulation, current activity and modeled structure respectively. None alone establishes an entry direction.
Return to price and observe acceptance, rejection or a break at a pre-marked area. If definitions and times match but discrepancies remain unexplained, retain the settings and screenshots for support.
Replay exercise
Pause at one instant and record two apparently conflicting readings. Complete all six checks before deciding whether the difference is definitional, structural or unresolved. Do not replace missing information with a story.
