# Limit Bid Strategy
> Paired YES/NO limit orders for guaranteed edge when both sides fill
The **Limit Bid strategy** places paired YES (Up) and NO (Down) limit buy orders on the same market simultaneously. If both sides fill at prices that sum to less than 100¢, a guaranteed profit is locked in regardless of the outcome.
Tap **Auto Trade** → **Create Task** → **Limit bid strategy**.
Auto Trade can place real orders in Live mode. Start with **Dry Run** and a small position size to validate your settings before going live.
## How it works
1. The bot places a YES limit order at your **Up limit price** and a NO limit order at your **Down limit price** on the same recurring market
2. If **both sides fill** → guaranteed edge locked in (e.g. YES at 20¢ + NO at 20¢ = 40¢ total cost, pays out 100¢)
3. If **only one side fills** → risk management kicks in via Time SL and Stop Loss
## Setup wizard
Toggle the tokens you want to trade. Green = selected, red = deselected.
Available: **BTC**, **ETH**, **SOL**, **XRP**, **DOGE**, **HYPE**, **BNB**
Toggle **5M** and/or **15M** recurring crypto markets. You can select both.
| Option | Description |
| ------- | ------------------------------------------------- |
| Dry Run | Simulates fills only — no real orders placed |
| Live | Places real CLOB orders on your Polymarket wallet |
The advanced screen groups settings into **Core**, **Filters**, and **Risk**.
| Setting | Description |
| ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Name | Rename the task |
| Trade size | Position size for each limit order |
| Up limit price | Limit price for the YES/Up order (e.g. `0.20$` = 20¢) |
| Down limit price | Limit price for the NO/Down order (e.g. `0.20$` = 20¢) |
| Total | Combined limit price for both sides (Up limit + Down limit, shown automatically) |
| Daily limit | Maximum USD to spend per day (`$0` = no limit) |
| Time stop loss | How long (in seconds/minutes) to wait for the second leg to fill after the first has filled. If this time expires: the open position is closed, the pending limit order is cancelled, and this market is skipped going forward |
| Time to place bids | How many seconds before a new market opens the bot should place limit bids |
| Stop loss | How much the first filled leg can drop before the position is closed while waiting for the second leg to fill, shown as price and percent |
| Max DD | Pause the task when realized P\&L drops by the selected drawdown from its peak |
| Max lose | Pause the task after N consecutive losing trades |
Review all settings in the summary screen, then either:
* **Start task** — create and immediately activate the task
* **Save without starting** — save in paused state
