Trading
Place trades on Polymarket prediction markets, manage positions, and protect your capital with conditional orders.
How Prediction Markets Work
A prediction market asks a yes/no question about a future event. You buy YES or NO shares.
- YES shares pay $1.00 if the event happens.
- NO shares pay $1.00 if it doesn’t.
- Prices reflect probability. YES at $0.65 = 65% implied chance.
- Profit = payout minus what you paid.
Example: Buy 100 YES shares at $0.40 (cost: $40). Event happens: you receive $100. Profit: $60. Event doesn’t happen: shares worth $0, you lose $40.

Risk Management
Set conditional orders on any open position. They execute automatically when price conditions are met.
Stop-Loss
Sells if price drops below your threshold. Protects against large losses.
- Open the position’s menu and select Add SL/TP.
- Enter a trigger price (must be below current price).
- Click Set Stop Loss.
Example: Buy at $0.60, set stop-loss at $0.48. Price drops to $0.48: auto-sell.
Take-Profit
Sells when price reaches your target. Locks in gains.
- Open the position’s menu and select Add SL/TP.
- Enter a trigger price (must be above current price).
- Click Set Take Profit.
Example: Buy at $0.30, set take-profit at $0.45. Price hits $0.45: auto-sell.
Trailing Stop
Dynamic stop that follows price up but never down. Tracks the highest price reached (high water mark) and sells if price drops a set percentage below it. Set this from your copy config’s risk management section.
Example: Buy at $0.50, 10% trail. Price rises to $0.80, stop moves to $0.72. Price drops to $0.72: auto-sell. You lock in 44% gain.
Managing Conditional Orders
Active orders show on the position card with colored badges:
- Stop Loss: Red badge with down arrow
- Take Profit: Green badge with up arrow
- Trailing Stop: Blue badge with activity icon
Each order card shows: trigger price, current price, distance to trigger, and a warning if price is within 5% of the trigger.
Actions on active orders:
- Edit: Change the trigger price
- Cancel: Remove the order
Order Statuses
| Status | Description |
|---|---|
| Active | Order is monitoring price |
| Triggered | Price hit the trigger level |
| Executed | Position was sold |
| Cancelled | You cancelled the order |
| Failed | Execution failed (details shown) |
| Expired | Order expired (market resolved) |
Stacking Orders
You can set multiple orders on the same position. A stop-loss at 20% below entry + take-profit at 50% above entry defines your full risk/reward range.
Don’t set stops tighter than 5%. Normal price fluctuation will trigger them.
