Understanding Polymarket Trading
Polymarket is a prediction market where you trade on the outcomes of real-world events. Each market has two outcomes: YES and NO. Prices range from $0.01 to $0.99, representing the market's probability estimate.
If you buy YES at $0.40 and the event happens, your shares resolve to $1.00 — a $0.60 profit per share. If it doesn't happen, your shares go to $0.00. You can also sell before resolution to lock in profits or cut losses.
Order Types Explained
Polymarket supports two order types. Market orders (FOK — Fill or Kill) execute immediately at the best available price but may have slippage in low-liquidity markets. Limit orders (GTC — Good Til Cancelled) let you set your price and wait for a fill.
Pro tip: Always use limit orders on crypto rolling markets. Limit (maker) orders have zero fees and earn rebates, while market (taker) orders pay ~2% fees. This single change can dramatically improve your profitability.
How to Buy Shares
Navigate to any market and click on the outcome you want to trade. Enter the price you want to pay (for limit orders) or accept the market price, and specify the dollar amount. Click Buy to submit your order.
Your shares appear in your Portfolio tab once the order fills. Monitor your positions and current P&L in real time. Each share is worth $1.00 if it resolves in your favor, $0.00 if it does not.
How to Sell and Take Profits
To sell, go to your Portfolio, click on the position, and hit Sell. You can sell at market price (instant) or set a limit sell price. Selling before resolution locks in your gain or loss at the current market price.
For automated selling, PredictEngine lets you set take-profit and stop-loss targets. Your bot automatically sells when price hits your target — no manual monitoring needed.
Beginner Strategies That Work
Start with markets you understand. If you follow the NBA, trade NBA game outcomes. If you track crypto, trade BTC price prediction markets. Domain knowledge gives you an edge over the market.
The simplest profitable strategy: buy shares priced under $0.10 or above $0.90 that you believe are mispriced. Near-resolution markets offer quick turnaround and lower risk when you have strong conviction.
