Places bubbles on candles where call premium (green, above) or put premium (red, below) was unusually large, sized by premium.
In plain English
What it shows
- Bubbles on candles where call premium (green, above) or put premium (red, below) was unusually large. Premium is the money paid for contracts.
- Bigger bubbles mean more premium. Tap a bubble for the details.
How traders use it
- Spot bars where options money was heavy and read the candle around it.
- Compare call and put bubbles across the day to see which side was more active.
What it does not tell you
- Strike and expiry are not in the data, so a bubble does not tell you which contract it was.
- Premium is estimated, and a large trade can be a hedge rather than a view.
Overview
Options Flow Marks highlights bars with heavy options premium. A green bubble above the candle marks large call premium; a red bubble below marks large put premium. Bigger bubbles mean more premium in that bar.
Hover or tap a bubble to see a card with calls or puts, the premium, the number of contracts and the net bought-minus-sold estimate. The card says plainly that strike and expiry are not in the data.
How it works
It uses the same per-minute options samples as ZoroTide for SPX, SPY and QQQ (ES and NQ charts map to SPX and QQQ). Samples are added up per chart bar, so each mark is a bar total across all contracts, not a single trade.
Within the visible bars, a bar qualifies when its call or put premium is in the top share for that side: 5% at Low sensitivity, 10% at Medium, 20% at High. The biggest marks are kept first, with at most one bubble every 3 bars. Bubble size scales with the square root of premium against the biggest mark.
How to use it
- Some traders watch where heavy call or put premium showed up during a move.
- Use it to see whether options activity clustered near a high, a low or a breakout.
- Some traders compare the bubbles with ZoroTide's running totals.
These are ways some traders read it, for learning. They are not trade signals.

Notes and limits
- Intraday charts only, on SPX, SPY, QQQ, ES and NQ.
- Premium is estimated from options volume and quotes.
- Nothing is drawn in bar replay, because the day's totals would show the future.
- Strike and expiry are not available, so the marks do not show which contracts traded.
