Data-backed strategies from 30,000+ backtested trades. Stop guessing. Start trading with an edge.
Not all Polymarket prices are created equal. Our backtest of 30,000+ closed positions reveals a clear pattern: markets priced between 30¢ and 55¢ produce the best risk-adjusted returns.
Why? At this price range, you are buying outcomes the market considers unlikely but that smart money sees differently. Below 30¢, events are cheap for a reason. Above 75¢, your upside is capped.
The mid-value strategy achieved a Sharpe ratio of 12.20 — meaning the returns far exceed the risk. Only 2% maximum drawdown across 714 trades.
| Entry Price | Win Rate | Sharpe | Max DD |
|---|---|---|---|
| Under 30¢ | 71% | 7.59 | 2.0% |
| 30¢ – 55¢ ⭐ | 80% | 12.20 | 2.0% |
| 55¢ – 75¢ | 85% | 8.24 | 5.0% |
| Over 75¢ | Low margin | Negative | High |
Score measures position size vs trader historical median
When a top trader places a bet significantly larger than their usual size, it signals high conviction. They see something the market is mispricing.
Polyburg calculates a conviction score from 1-10 for every signal. Our backtesting shows that filtering for conviction scores of 7 or higher dramatically improves outcomes — these traders are putting their money where their mouth is.
The high-conviction strategy (score 7-10, top-10 traders) achieved +818% returns with a 9.43 Sharpe ratio and only 2.6% max drawdown.
Never risk more than 2% of your balance on a single trade
Keep 30% cash reserve for new opportunities
Stop trading if portfolio drops more than 15% from peak
With a $1,000 account, each position is $20. With $10,000, each position is $200. This means a single losing trade never moves your portfolio more than 2% — you would need 50 consecutive losses to wipe out your account.
As your account grows through compounding, your position sizes grow proportionally. A $10,000 account at 2% sizing that grows to $50,000 now places $1,000 per trade —compounding accelerates returns without increasing risk percentage.
The highest Sharpe ratio in our portfolio backtests came from the Diversifier strategy: spreading bets across categories, events, and traders.

| Combined Vault | +2,722% | 11.92 |
