PancakeSwap Prediction Bot

A small bot that places Bull or Bear bets on PancakeSwap Prediction (BSC). It runs in the background, reads past round results, and only bets when its internal “edge” score is high enough.

What it does

• Connects to the BNB prediction contract on BSC (you can point it at ETH/BTC contracts too via config).
• Every 15 seconds it checks the current round and the last ~20 rounds.
• If the strategy says “bet” and we’re still in the betting window (before lock), it sends one bet at your chosen size.

No UI, no dashboard—just a single process. You run it and watch your wallet or logs.

How the strategy works (plain English)

• Momentum
  It looks at recent rounds: did price go up or down more often? Recent rounds count more than older ones. It only bets when one side is clearly ahead (above a minimum “edge” you can set).

• Streak reversal
  If the last 3 (or more) rounds were all Bull or all Bear, it assumes a reversion and bets the opposite side once.

• Safety

  • Won’t bet in the lock window (too close to round end).
  • Respects a max bet size.
  • You can add a short “cooldown” after a loss so it skips the next round or two.

So: it’s a mix of “follow recent trend” and “fade long streaks,” with simple risk limits.
