0DTE options flow

Call/put volume, put-call ratio, net premium and bought/sold flow on the 0DTE options, CME (ES, NQ) or ETF (QQQ, SPY).

Updated 8 October 2026

Options expiring the same day (0DTE) are a significant driver of intraday moves. Konsole follows their flow in real time, on two chains:

  • the CME options on ES and NQ, from your own Rithmic (Pro and Desk). ES and NQ have options expiring every day: the app follows the front expiry, and moves to the next day’s after the 16:00 New York expiry;
  • the QQQ and SPY 0DTE options, served by us (Desk). Desk is coming soon: the waitlist is on the pricing page.

Which chain a panel reads, and how to choose it on Desk, is in GEX and the flip point.

What to watch

  • Call / put volume, how much is trading on the bullish (call) and bearish (put) side.
  • Put-Call Ratio (PCR), the ratio of puts to calls; a compact way to read the imbalance.
  • Net premium, the net premium traded (calls minus puts): an estimate of how money is positioning in options.
  • Bought or sold, the side that took each trade. On the CME source the side comes from the exchange.

Where to find it

In the Workspace library, under Options & GEX:

  • Options 0DTE, options metrics (IV, GEX, premiums, greeks) and Net GEX by strike.
  • Options flow, six time views of the call/put flow, to spot direction changes.
  • Premium Drift, the session’s call, put and net premium, with a flow bias reading.
  • Net Vol, net options volume (call − put), cumulative for the session or in one-minute bars.
  • Weighted flow, the flow weighted by delta and gamma and signed by the aggressor: the exposure that moved, not the contract count.
  • Flow by side, contracts bought or sold in calls and puts, split by moneyness at print time.

On the chart, the Option Whales (0DTE) indicator draws the large blocks at the height of their strike.

On the CME source the curves over time start from when the app is running.

Options positioning is what feeds GEX and its levels. To see how it turns into gamma exposure and a flip point, carry on with GEX and the flip point.

The QQQ and SPY options trade only during the regular session (RTH): their flow is meaningful in those hours. The CME options on ES and NQ trade on the futures’ electronic session (Globex).
