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

   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
