You're a better trader than your results. One habit is the gap.
QuantBias measures the bias cost in your own trades — with peer-reviewed statistics and a dollar cost attached, only when the math supports it. We're inviting 50 traders per week. Get on the list.
No credit card. No spam. Invites going out weekly. We'll never share your data.
Built on the research traders actually need.
Every bias QuantBias measures is operationalized from a peer-reviewed paper — roughly 33 academically-grounded detectors across behavioral, perceptual, and market-context signals.
One mirror. Three things it reads.
Your trade history
Reads your closed trades.
Disposition effect, revenge trading, hot-hand, sunk cost, mental accounting, and more.
Your chart context
Reads the chart in front of you.
Anchoring, representativeness, confirmation, pattern-in-noise, recency on chart.
The market state
Reads the state of the market when you click buy.
FOMC day, news reactivity, earnings-window, high-VIX, sector rotation.
We're not gating you to manufacture demand.
We onboard 50 traders per week so we can read every flag, hear every complaint, and fix every edge case before public launch.
If your trades fire a false positive on revenge trading, we want to know within 24 hours — not 24 weeks. So we're slow on purpose, until we're confident every flag is calibrated.
Beta access is free for 90 days. Founding Trader pricing ($10/mo locked for life, instead of $99) is reserved for the first 100 paying after public launch.

Frequently asked.
How long until I get my invite?+
Typically 2-4 weeks from waitlist signup. We send 50 invites per cohort, every Tuesday.
What brokers do you support?+
IBKR for live trading. SnapTrade for read-only sync from most retail brokers (Robinhood, Webull, Schwab, Fidelity, and 50+ others). Crypto and futures coming.
Is this investment advice?+
No. We never recommend tickers, directions, or sizes. We only flag patterns in your own behavior. All decisions remain yours.
What happens to my data?+
Encrypted at rest. Never shared with third parties. Full export available anytime in CSV + JSON.
What if I don't have enough trade history?+
You'll get directional patterns on imports under 30 trades. Statistical significance and personalized baselines kick in at N≥30. The mirror still works — it just labels flags as "indicative" vs. "statistically significant."
Stop blaming the market. Start measuring yourself.
