How to Read Drift

Use Drift to compare selected 0DTE call and put premium with the underlying price. The chart covers scored unusual-flow signals from a rolling four-hour window.

Traders may know this layout as net drift. GEX Edge calls it Drift because our feed is narrower. It shows selected activity instead of every options trade or a session-to-now total.

Green is call premium, red is put premium, and blue is price. Buys add premium to the call or put line. Sells subtract it.

The premium lines move in steps because option trades arrive at separate times. A flat stretch means no new signal qualified. Options can still be trading outside the selected feed.

Reading the chart

Start with the latest meaningful step, then check what price did next.

Rising call premium with rising price gives a cleaner bullish read. Rising put premium with falling price gives a cleaner bearish read. The option demand and price move agree.

If call premium jumps while price stalls, the market can be absorbing that demand. Wait for price to break higher or reject the move.

If put premium jumps while price holds, those puts may be protection. Let the next price move show whether sellers have control.

When both premium lines rise quickly, the selected flow is two-sided. Give the price response more weight.

Trade-side limits

The feed shows whether buying or selling crossed the market. Opening, closing, hedging, and multi-leg intent remain unknown.

Midpoint trades stay out of the signed lines because they lack a clear buy or sell side.

When a large premium step looks directional but price refuses to follow it, treat the step as activity until price confirms a direction.

Drift and GEX

Drift shows transaction pressure. GEX shows the option structure that dealers can hedge.

Call premium can rise below a strong call wall while the wall still limits the advance. Put premium can rise above a strong put wall while the wall still supports price.

Check the Gamma Flip and the nearest walls after you read the flow. They show how much room price has before it reaches heavier structure.

The rolling window

The four-hour window moves forward with time. When a selected trade becomes more than four hours old, Drift removes it from the calculation.

Removing old premium changes the cumulative line, even when no new trade arrives. Check the displayed window and the Flow updated time before you label a step as new demand.

Data quality

Drift shows separate Flow updated and Price updated times. The older source controls the overall status.

• Fresh: Both sources are current.
• Thin: Few selected signals qualified, so use less confidence.
• Limited: The source reached its result limit, so part of the window can be missing.
• Stale: The chart keeps the last accepted same-session data. Treat it as old data.
• Closed: The chart shows the dated final view from the last eligible session.
• Unavailable: The sources cannot support an accurate chart. Treat missing data as unknown flow.

Read the status before the last step. Reduce confidence when the sample is Thin or Limited. Stop when it is Stale or Unavailable.

Data coverage

A full Net Drift feed can include every trade in a selected chain range. It can also show session totals, midpoint values, volume, and a chosen date range.

GEX Edge Drift uses exact 0DTE signals from a scored four-hour sample. Midpoint trades do not enter the signed lines, and the chart has no historical session selector.

Expect different totals from a provider that uses the full tape. Compare how the selected flow behaves against price instead.

Before a trade

Find the last meaningful call or put step. Check whether price confirmed it. Then check the sample status, the Gamma Flip, and the nearest wall.
