When the option's strike price equals (or is very close to) the current stock price.

A call is ITM when the stock price is above the strike. A put is ITM when the stock price is below the strike. ITM options have intrinsic value.

A call is OTM when the strike is above the current price. A put is OTM when the strike is below the current price. OTM options have no intrinsic value — only time value.

The 'real' value of an option — how far it is in-the-money. A $200 call on a $210 stock has $10 of intrinsic value.

The portion of an option's premium beyond its intrinsic value — what you pay for time and implied volatility. This is what theta erodes each day.

The total dollars spent on an options trade — contracts x price x 100. It's the size of the bet.

The price at which an option lets you buy (call) or sell (put) the stock.

The date the option contract expires and stops trading.

How many calendar days until the option expires.

How many contracts traded today on this option.

The number of contracts currently held open on this strike (not yet closed or expired).

The percentage change in shares owned by an insider as a result of their reported trade. A large change means the transaction was significant relative to their existing stake.

Private exchanges where large institutional trades are executed away from public markets, often to avoid moving the price. Dark pool prints can signal large accumulation or distribution.

An order split across multiple exchanges and filled instantly — the buyer wanted in NOW and paid up to get filled.

Our highest-tier sweep — a large, aggressive, multi-exchange order that clears our strictest size and urgency bar.

A single large trade negotiated privately and printed at once — classic institutional footprint.

A larger order broken into smaller pieces, often to reduce market impact.

Our 0-100+ rating of how unusual a trade is — blending size, volume-vs-open-interest, urgency, and other signals.

The same strike getting hit multiple times within about an hour — someone is accumulating one contract on purpose.

Which direction a trade is betting. Bought calls / sold puts lean bullish; bought puts / sold calls lean bearish.

The percentage of historical unusual-activity signals where the underlying stock moved in the same direction as the flow's sentiment by the end of the measured window.

The average percentage change in the stock price in the same direction as the flow's sentiment after the specified number of days.

How many of the 9 technical reversal indicators are firing for a ticker at once. A score of +9/9 means all 9 are aligned in the same direction.

The total dollar premium spent across all repeat flow hits on this contract within the lookback window. More stacked premium means larger cumulative bets on the same strike.

How many days before an earnings report a flow was captured. EARLY = more than 14 days out. THESIS = 7-14 days out. LATE = 3-7 days out. IMMINENT = 3 days or fewer.

The percentage of flows pointing in the same direction for a given ticker or event. 100% means every detected flow agreed on direction; below 50% means flows were split.

A condition where different signals or participants disagree in direction. In ETF tracking, it means at least one provider is buying a ticker while another is selling it.

Compares current implied volatility to the stock's 52-week IV range. An IV Rank of 80 means current IV is in the 80th percentile of its yearly range — historically expensive.

The market's expectation of how much a stock will move, baked into the option's price.

How much dealers must buy or sell to stay hedged as price moves. It measures volatility pressure, not direction.

Where the strike sits vs the stock price: In-, At-, or Out-of-the-Money.

The range the options market is pricing in for a stock by a given date — often used around earnings.

A scanner score that ranks how much activity a name is seeing relative to its premium — surfacing overlooked, active tickers.

The price where your trade idea is proven wrong — if it trades or closes through this level, the setup has failed and the reason you entered no longer holds.

A strike where dealers hold large positive gamma from sold calls. Price tends to stall or reverse near this level as dealers sell into rallies to stay hedged.

A strike where dealers hold large put gamma, acting as a price floor. Dealers buy the underlying when price drops here, which tends to slow the decline.

The price level where dealer gamma exposure crosses from positive to negative. Below this level dealers amplify price moves; above it they tend to dampen them.

Today's volume as a multiple of the 30-day average volume for that ticker. 2.0x means twice the normal daily activity.

For put selling (CSP/Wheel strategy): the premium collected divided by the capital at risk (strike × 100). A 1% weekly ROC means $1 earned per $100 of collateral held.

Selling a put while holding enough cash to buy the stock if assigned. You collect premium and may get the stock at a discount.

Selling a call against stock you already own to collect premium, capping your upside in exchange for income.

A repeating income strategy: sell cash-secured puts until assigned shares, then sell covered calls until they're called away — and repeat.

How much value an option loses each day just from time passing.

How much an option's price changes for every $1 move in the underlying stock. A delta of 0.50 means the option gains $0.50 when the stock rises $1. Also approximates the probability of expiring in-the-money.

The rate at which delta changes as the stock price moves. High gamma means delta changes rapidly, making the option more sensitive as it nears expiration.

How much an option's price changes with a 1% change in implied volatility. Long options profit when IV rises; short options profit when IV falls.

How much an option's price changes with a 1% change in interest rates.
