Questions & Answers

As answered by people managing SpectralEdge by Cotes and Nullstack.

What's the story behind your product?

SpectralEdge by Cotes's answer

SpectralEdge is built by Cotes AI, which researches trading signals for prediction markets. Kalshi's 15-minute bitcoin markets are fast and price in odds directly, which makes it easy to see when a high win rate still loses money at the price paid. SpectralEdge was built to signal only when the probability and the price both favor the call.

What makes your product unique?

SpectralEdge by Cotes's answer

  • It covers one market type: Kalshi's BTC 15-minute markets. It reads every one of them every 5 seconds from open to resolution.
  • It fires only when calibrated confidence clears a fixed threshold and the contract price leaves a positive edge, so a high win probability alone isn't enough.
  • Every signal shows its direction, confidence, entry price and edge.
  • Thresholds are fixed before each market resolves, and accuracy is scored on the first signal per market, never on a signal picked after the fact.
  • Replays of past markets show how each signal played out.

Why should a person choose your product over its competitors?

SpectralEdge by Cotes's answer

SpectralEdge publishes the numbers behind every call (confidence, entry price and edge) and holds itself to rules that are set before the outcome is known. Its out-of-sample backtest covers 12,000+ markets under the same policy it runs live, and you can replay past markets to check it yourself. It never touches your money: you trade in your own Kalshi account. Developers get the same signals over a public JSON/SSE API.

How would you describe the primary audience of your product?

SpectralEdge by Cotes's answer

  • Traders active in Kalshi's BTC 15-minute markets who want a second read before taking a side
  • Crypto traders exploring prediction markets as a short-horizon way to express a view on bitcoin
  • Developers and quants building their own tools or bots on top of a live signal feed via the API
