SignalVector runs five independent signal sources across Kalshi and Polymarket to find mispriced contracts. Every trade is Kelly-sized, passes ten risk checks, and exits on rules, not impulse.

The problem
Your current setup
The engine
Each source runs independently. SignalVector only surfaces contracts where the weighted composite exceeds 0.62 and at least three sources agree on direction.
28%
AI Analysis
LLM reads contract language, resolution criteria, and recent news. Outputs directional probability vs market price. Weighted highest when narrative and price diverge sharply.
22%
Price Momentum
Tracks short-horizon price velocity and mean reversion signals on the contract tape. Flags contracts moving against implied fair value.
18%
Volume Spikes
Detects abnormal volume relative to 7-day baseline on the same market. Often precedes informed flow before the price fully adjusts.
17%
Market Efficiency
Measures bid-ask spread, depth at top of book, and slippage on a standard clip size. Penalizes illiquid contracts where edge cannot be captured.
15%
Time Decay
Models theta on contracts approaching resolution. Favors entries with favorable time-to-event profiles. Reduces exposure as uncertainty collapses near expiry.
Composite threshold: 0.62 minimum · 3-source agreement required · rescanned every 30 minutes
