Glossary
Every abbreviation this product puts on screen, written out in full and explained in one sentence. Where a measure has a limit — something it cannot tell you, or an assumption it rests on — that limit is part of the definition rather than a footnote somewhere else.
These are the same definitions the tooltips use. There is one copy, in lib/glossary.ts, so a term cannot mean one thing here and another on the screen that shows it.
- Level 2 (order book)l2
- Every resting buy and sell order at each price, not just the best bid and offer.
- It shows where size is waiting. Resting orders can be pulled the instant price reaches them, so depth is intent, never a promise.
- Cumulative Volume Deltacvd
- A running total of volume that traded into the offer minus volume that traded into the bid.
- It separates buying that lifted offers from selling that hit bids, so price and CVD disagreeing is the signal — price up on falling CVD means the move is not being paid for.
- Anchored VWAPavwap
- The volume-weighted average price measured from one chosen bar forward, rather than from the session open.
- Anchoring to an event — a gap, an earnings print, a high — shows the average price everyone who traded since that event has paid.
- Point of Controlpoc
- The single price at which the most volume traded over the period.
- It is where the most business got done, which is why price often returns to it.
- Value Area Highvah
- The upper edge of the price band that contains about 70% of the period’s volume.
- Above it, price is outside the range most of the period’s trade agreed on.
- Value Area Lowval
- The lower edge of the price band that contains about 70% of the period’s volume.
- Below it, price is outside the range most of the period’s trade agreed on.
- Open, High, Low, Close, Volumeohlcv
- The five numbers that define one price bar: where it started, its extremes, where it ended, and how much traded.
- Simulatedsim
- This figure is computed from a placeholder, not from a live market feed.
- It is badged rather than hidden so a demo can never be mistaken for a fill. Anything marked SIM must not be traded on.
- Relative Volumerelvol
- Today’s volume so far, divided by the usual volume by this time of day.
- Above 1 means more interest than normal — it says nothing about direction.
- Unusual Volumeunusual_volume
- Names trading far more than their own recent average.
- Unusual is relative to the name itself, so a quiet stock qualifies on much less volume than a busy one.
- Open Interestoi
- The number of contracts that exist and have not yet been closed out.
- Volume counts what changed hands today; open interest counts what is still on the books. Rising price with rising OI means new positions, not just churn.
- Gamma Exposuregex
- An estimate of how much dealers must buy or sell to stay hedged as price moves.
- It is an ESTIMATE built on an assumption about who is on which side of each contract — it is a map of likely dealer behaviour, not an observed flow.
