Limit Orders

Set your target entry price and walk away. PredyX monitors the market and executes automatically the instant the price is right.

⚡

Sub-200ms execution. When your limit price is reached, PredyX places the order in under 200ms — faster than any manual trade possible via browser.

How Limit Orders Work

A limit order watches a Polymarket market for a specific price level on YES or NO shares. When the market price reaches your target, PredyX executes a market order immediately on your behalf.

ℹ️

Polymarket uses an order book model. PredyX limit orders are trigger-based — when your price is reached, PredyX submits a fill-at-market order, not a resting limit order on the book. This guarantees fills but may have slight slippage in low-liquidity markets.

Placing a Limit Order

Command Syntax

/limit [market] [YES|NO] [amount_usdc] [target_price]

# Examples:
/limit https://polymarket.com/event/btc-100k YES 50 0.65
/limit https://polymarket.com/event/fed-cut   NO 100 0.40

Parameter	Description	Example
`market`	Polymarket event URL or market ID	`https://polymarket.com/event/btc-100k`
`YES \| NO`	Which side of the market to buy	`YES`
`amount_usdc`	How many USDC to spend on the trade	`50`
`target_price`	Price (0.01–0.99) at which to trigger the order	`0.65`

Interactive Mode

Type /limit without arguments to use the interactive flow:

Find Market

Paste a Polymarket URL or search by keyword. PredyX confirms the market name and current price.

Choose Side & Amount

Select YES or NO. Enter the USDC amount you want to spend.

Set Target Price

Enter your target entry price (0.01–0.99). PredyX shows estimated shares at that price and confirms.

Order Confirmation

After creating a limit order, PredyX confirms with a summary:

✅

Managing Limit Orders

Command	Action
`/positions`	View all pending limit orders and open positions
`/limit cancel [id]`	Cancel a pending limit order before it triggers
`/limit list`	Show all active (unexecuted) limit orders

Limit Order Expiry

Limit orders do not expire by default — they watch indefinitely until triggered or cancelled. You can set an optional expiry:

/limit [market] YES 50 0.65 --expires 7d   # auto-cancel after 7 days
/limit [market] YES 50 0.65 --expires 2025-06-01

Fees

Limit order execution carries no additional fee beyond Polymarket's standard protocol fee. PredyX charges no fee for limit orders. See Fees & Pricing.
