Trading Strategies
1. Spread Arbitrage (Practice)
Buy both YES and NO when combined < $1.00.
Example:
Market: "Will Bitcoin hit $100k?"
YES: $0.48
NO: $0.50
Combined: $0.98
Trade: Buy $490 YES + $500 NO = $990 total
Guaranteed payout: $1,000
Profit: $10 (1.01%)
2. Endgame Trading
Buy near-certain outcomes close to resolution.
Example:
Market: "Will X happen by March 31?"
Current: March 28
YES price: $0.97
Days remaining: 3
Trade: Buy YES at $0.97
Hold until resolution at $1.00
Profit: 3.1% in 3 days (376% annualized)
3. News Correlation
Trade on news before market adjusts.
Example:
News: "Israel strikes Tehran. Trump demands surrender."
Market: "Will Trump declare war on Iran?" @ 40%
Analysis: Military action ≠ formal war declaration
Market likely overpriced
Trade: Sell YES (or buy NO)
