Crucible
Latency is the edge._
The System
Autonomous prediction market trading
Crucible trades 15-minute crypto prediction windows on Polymarket: BTC, ETH, SOL, XRP. Each window is a binary question: will the price be above or below a threshold at resolution? The market creates UP and DOWN tokens. Both resolve to either $1 or $0.
Crucible's edge is structural. Buy both sides across the price range. Hold to resolution. Winning tokens pay $1. Matched pairs bought below $1 combined are guaranteed profit. Unmatched winners are pure upside. The system positions.
Architecture
Six concurrent systems. Zero central control.
Trader
Core execution engine. Phase 1 budget dump across 37 price levels. Phase 2 stagger repricing with geometric decay over 10 minutes. Balance-aware gating blocks posting on the heavy side.
Monitor
Real-time position tracking. Watches fills, calculates exposure, triggers exit strategies. Three modes: EXPOSED_SELL at 30%+ profit, CLOB_EROSION_CUT when bids drop, REVERSAL_CUT on price whipsaws.
CLOB Feed
WebSocket connection to the Central Limit Order Book. Real-time bid/ask data. Every market movement visible. The data that drives every decision.
Price Feed
Real-time data stream from external price feeds. The ground truth that the prediction windows orbit. BTC, ETH, SOL, XRP. Tick-by-tick.
Market Discovery
Gamma API integration. Discovers new 15-minute windows as they open. Filters for tradeable conditions. Feeds the trader with fresh opportunities.
Recorder
Every order, every fill, every decision. Logged and timestamped. Full audit trail. Backtestable. Nothing happens in the dark.
Strategy
Hold to resolution
Most traders try to predict direction. Crucible doesn't. It buys both UP and DOWN tokens across a range of price levels, creating matched pairs. When a matched pair costs less than $1 combined, the profit is locked in before the window even opens.
Unmatched positions on the winning side resolve at $1. Unmatched positions on the losing side resolve at $0. The strategy profits when matched-pair savings plus unmatched winners exceed unmatched losers. Geometric decay pricing ensures disciplined entry.
Execution
Two phases. Geometric precision.
Budget Dump
37 limit orders across the price range, placed in the first seconds of each window. Speed matters. Early orders get better prices. Budget distributed to maximise coverage while maintaining profitable pair costs.
Stagger Repricing
Over the next 10 minutes, unfilled orders are repriced with geometric decay. Each reprice offers slightly worse prices but increases fill probability. The decay rate balances aggression with profitability. Markets that move against positions trigger exit strategies.
Risk Management
Three exits. No emotion.
Unmatched position shows 30%+ profit on the book. Take it. Don't wait for resolution when the money is already there.
Best bid drops below 62% of entry price. The market is walking away from your position. Exit before it gets worse.
Price whipsaws against your unmatched side. The structural advantage has evaporated. Cut and preserve capital for the next window.
