Signal Confidence —

—

How much weight to put on this read. High means stronger call/put imbalance, larger activity, tighter quotes, and better data coverage. It does not confirm buy/sell or open/close direction.

Data Quality —

—

Snapshot quality. Capped because chain data cannot confirm true tape direction.

📗 Call Wall

—

Strike with the highest call open interest. This is a potential positioning and hedging reference, not guaranteed resistance.

⚖ Max Pain

—

Theoretical strike that minimizes total option-holder payout for this expiration. Use as a reference only; it is not a price prediction.

📕 Put Wall

—

Strike with the highest put open interest. This is a potential positioning and hedging reference, not guaranteed support.

What is Options Flow?

Options flow is the real-time tracking of call and put option orders, showing where large institutional traders and hedge funds are placing directional bets. Heavy call buying signals bullish conviction; heavy put buying signals bearish expectations. Monitoring flow gives retail traders a window into smart-money positioning before major price moves occur.

What Are Call Wall & Put Wall?

The Call Wall is the strike price with the highest concentration of call open interest. Market makers must sell shares as price rises toward it (gamma hedging), creating natural resistance. The Put Wall is the opposite — the strike with the most put open interest, where dealer buying provides natural support. Traders watch these levels as price magnets and reversal zones.

What is Max Pain?

Max Pain is the strike price at which the total value of all expiring options contracts is minimized — meaning the most contracts expire worthless and option sellers (usually market makers) profit most. As expiration approaches, the underlying stock often gravitates toward the max pain level. It is not a guarantee, but it is a useful reference for where the market "wants" to settle.

How to Use the Flow Score

The Flow Score (0–100) combines call/put volume split, premium split, and unusual activity direction into a single bullish/bearish reading. A score above 60 indicates net bullish positioning; below 40 is net bearish; 40–60 is neutral. Use it alongside the raw volume and unusual activity tables — the score is a quick summary, not a trading signal on its own.
