FlowReads contract volume, premium, and open-interest pressure at the row level.
SpeedRefreshes the active scan around current chains, quote moves, and calendar risk.
SignalSeparates call-led and put-led pressure while keeping volatility cost visible.
ContextConnects option demand to filings, headlines, targets, and earnings windows.
Built for contract-level review
See the pressure, then check the reason.
ConvexRadar starts with the option contract, then layers in liquidity, IV rank, directional pressure, and catalyst timing so fewer rows deserve your attention.
Ranked contracts
Score the setup before opening the chart.
Candidates are weighted by liquidity, V/OI, IV rank, delta, gamma per premium, premium value, sector context, and catalyst proximity.
Fresh pressure
Spot where today’s volume overwhelms stale OI.
The scanner emphasizes volume/open-interest imbalance, premium traded, call/put bias, and short-dated convexity instead of treating every active ticker as equal.
Custom filters
Narrow the board without losing context.
Filter by side, DTE, LEAPS, sector, market type, IV rank, V/OI, score, liquidity, ticker, and company name while keeping catalysts nearby.
Daily options workflow
A cleaner path from scan to watchlist.
Use the same repeatable review loop each morning so unusual option flow becomes a short list of setups to verify, not a wall of noisy rows.
02
Check if the move has a reason.
Use earnings, filings, target changes, news, sector context, and calendar risk to separate real catalysts from noisy flow.
03
Open the chart and mark levels.
Use the chart toolbar to draw trendlines, support, resistance, and invalidation zones before acting on an option signal.
04
Save it and measure follow-through.
Star contracts into Favorites so later snapshots can track option-price movement, drawdown, peak move, and repeat pressure.
What creates noise
Single-factor alerts that treat high volume as a trade idea without IV, OI, or catalyst context.
Mixed-direction pressure where calls and puts are both active but the setup is still ranked as clean.
Untracked ideas that disappear after the alert, making it hard to learn which signals actually followed through.
What ConvexRadar emphasizes
Contract-first scoring with volume/OI, premium, IV rank, delta, gamma per premium, and side bias in the same row.
Reason before conviction by placing catalysts, calendar risk, target updates, and chart review beside the signal.
Saved-signal tracking so favorites, repeat flow, and performance history can show what happened after discovery.

What does ConvexRadar look for?
ConvexRadar looks for US stocks and ETFs where option demand, volume/open-interest imbalance, IV rank, premium value, gamma per premium, and catalyst timing line up in the same contract.
Who is ConvexRadar built for?
The scanner is built for active options traders who want to review fewer, cleaner contracts. It is research software, not financial advice, and it does not replace risk management or position sizing.
How is this different from a watchlist?
A watchlist starts with a symbol. ConvexRadar starts with the option contract and adds side, expiration, liquidity, IV, premium, catalyst, and call/put context around it.
What data does ConvexRadar use?
The live product combines option-chain rows and quotes with enrichment from public filings, company context, headlines, earnings calendars, analyst target updates, and charts. Paid data upgrades are planned as revenue supports them.
Is ConvexRadar the same as Convex Radar?
Yes. The official product name is ConvexRadar, written as one word. Some traders search for it as Convex Radar; both names refer to the same US options flow scanner.
