Auto Trading
Auto trading lets Merlin automatically buy into Polymarketβs short-cycle up/down markets (5m, 15m, 1h) when conditions match your configured filters. You set the rules β Merlin watches the market and executes.
How It Works
Polymarket runs recurring up/down markets for tokens like BTC, ETH, SOL, and others. Each market resolves after a fixed cycle (5 minutes, 15 minutes, or 1 hour). Auto trading monitors these markets in real time and places a buy order when:
- The token matches your selected tokens (e.g., BTC, ETH)
- The cycle matches your selected cycles (e.g., 5m, 15m)
- The trade happens within your entry window (e.g., last 35 seconds before resolution)
- The price is within your configured range (e.g., 70c-92c)
When all conditions are met, Merlin buys the outcome token at the current price.

Start with Closing Bell to get a feel for how auto trading works. Itβs the most conservative preset with high win probability.
Configuration Parameters
Select which tokens to trade. Available tokens: BTC, ETH, SOL, DOGE, XRP, HYPE, BNB. You can enable or disable individual tokens from the picker.
Select which market cycles to monitor: 5m, 15m, 1h. Shorter cycles have more frequent opportunities but tighter timing.
Price Range (Min/Max)
The minimum and maximum price in cents (1-99) for the outcome token. Only trades where the price falls within this range will trigger a buy.
- High range (e.g., 70-92c): Buys outcomes the market considers likely. Higher win rate, lower payout.
- Low range (e.g., 26-35c): Buys outcomes the market considers unlikely. Lower win rate, higher payout.
Entry Window (Seconds Before Close)
How many seconds before market resolution the bot is allowed to enter. A smaller window means more certainty about the outcome but fewer opportunities. A larger window gives more chances but at less predictable prices.
Amount Per Trade
The fixed dollar amount Merlin spends on each trade.
Spent Limit
Cap the lifetime USD an auto-trading config can spend. When the running total reaches your limit, Merlin pauses the config and sends you a notification with a deposit link.
- π° Spent Limit β tap to set the cap (e.g., $500). Send
none to clear.
- π Reset Spent β clears the running total back to $0 without changing the limit.
Managing Configs
From the config detail screen:
- Start / Pause β toggle the config on or off
- Edit parameters β tap any parameter button to update tokens, cycles, price range, entry window, or amount
- Rename β give the config a custom name
- Delete β permanently remove the config
Bulk Actions
From the auto trading dashboard:
- Pause All β pauses every active config
- Start All β starts every paused config
- Delete All β permanently removes all configs
Each bulk action asks for confirmation before executing.
Auto-Claim
When your auto trading positions resolve as winners, Merlin automatically claims the winnings back to your wallet. No manual action needed.
Insufficient Balance
If your wallet runs out of funds, Merlin pauses the config automatically. Youβll receive a notification with a deposit link. After depositing, restart the config manually from the detail screen.
