Trading Strategy

Finding Opportunities

1. Run polymarket markets to see trending markets
2. Research the underlying events via web search
3. Compare market odds to your own probability estimate
4. Calculate edge: Edge = Your_Probability - Market_Probability

Example Analysis

Market: "Will Iran regime fall by June 30?"
Current Price: Yes = $0.42 (42% implied)
My Research: Given Khamenei killed, power vacuum exists
My Estimate: 60% probability
Edge: +18% → BUY YES

Position Sizing

• Never risk more than 5% of bankroll on single trade
• Recommended: 2-5% per trade
• Diversify across uncorrelated events

Risk Rules

1. Always verify balance before trading
2. Start with small positions (test the waters)
3. Don't bet more than you can afford to lose
4. Set mental stop-loss at 50% of position

Notes

• All trades are on Polygon network
• Minimum trade size typically $1
• Fees are small but apply to each trade
