Diffee VS SpectralEdge by Cotes

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.

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.

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.

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
