Order Terminal — Direct Execution with Live Order Book

Place limit orders on any Polymarket market with a live order book, real-time signals, slippage estimates, and fill tracking every 3 seconds.

The Order Terminal at /execute gives you direct access to Polymarket’s CLOB (Central Limit Order Book). You see the live order book, market condition signals, a slippage estimate before you commit, and real-time fill tracking after you submit. It’s designed for traders who want precise control over execution rather than market orders.

Selecting a market

Use the market picker at the top of the page to search from 1,000+ active markets. Start typing a keyword — “Fed”, “Bitcoin”, “NBA” — and select the market from the results. The order book and signals load immediately.

Live order book

The order book shows the top 5 bids and asks with depth visualization bars so you can see where the real liquidity sits at a glance.

Column	What it shows
Asks (top half)	Prices sellers are willing to accept, lowest first
Bids (bottom half)	Prices buyers are willing to pay, highest first
Spread	Difference between best ask and best bid, shown in basis points

A tight spread means lower execution cost. A wide spread means you pay more to enter and receive less when you exit.

Market signals

Once a market is selected, Kuroko’s signal engine analyzes the order book and recent market data to surface honest, data-grounded signals. Every signal has a verifiable source.

TIGHT_SPREAD

Bid/ask spread under 2%. Low execution cost — good conditions to enter or exit cleanly.

HIGH_ACTIVITY

Volume over $500K combined with a 24h probability move over 3pp. The market is live and actively repricing.

MOVING

Probability shifted more than 5pp in the last 24 hours. An active repricing event is in progress.

LIQUID

Combined order book depth over $50K or total liquidity over$200K. Large orders can fill without significant slippage.

NEAR_RESOLUTION

Market closes within 7 days. Time value is real — the probability will converge to 0 or 100 soon.

WIDE_SPREAD

Spread over 5%. Warning: execution cost is high. Consider using a limit order closer to mid-price.

LOW_VOLUME

Total volume under $10K. Warning: thin market. Getting out of a position may be difficult.

Placing an order

1. Select a market

   Search and select the market you want to trade. The order book and signals load automatically.

2. Choose your side and shares

   Select YES or NO. Enter the number of shares you want to buy. The order form calculates cost, payout, and return in real time.

3. Set a limit price

   Enter your limit price — the maximum price per share you’re willing to pay. The form shows the current best ask so you have a reference point.

4. Review the order summary

   Before submitting, check the order summary:

   • Cost — total dollars you’ll spend
   • Payout if correct — total payout if the market resolves in your favor
   • Return % — (payout − cost) / cost
   • Slippage estimate — estimated slippage in basis points, calculated by walking the live order book for a $100 order size
   • Bankroll warning — shown if this trade exceeds 10% or 20% of your set bankroll
5. Submit

   Click Execute. With a wallet connected, your wallet signs the order. The signed order is submitted to Polymarket’s order book.

Bankroll warnings

Set your total trading bankroll in the order terminal. Kuroko uses this to provide position sizing context as you enter orders.

A yellow warning appears when a single trade would exceed 10% of your bankroll. An orange warning appears when it would exceed 20%. These are informational — they do not block execution.

Fill tracking

After submitting an order, Kuroko polls the CLOB API every 3 seconds for up to 60 seconds to track fill status. The status indicator updates in real time.

Status	Meaning
PENDING	Order submitted, waiting for acknowledgment from the CLOB
OPEN	Order acknowledged and sitting in the order book, waiting for a match
MATCHED	Order has been matched with a counterparty
FILLED	Order fully executed — shares are now in your position
CANCELLED	Order cancelled before filling
REJECTED	Order rejected by the CLOB (e.g., price out of range)

Once the order reaches FILLED status, the trade is recorded to your history automatically.

Paper mode

If no wallet is connected, the order terminal runs in paper mode. The full flow works identically — you see the same live order book, signals, slippage estimate, and fill tracking animation — but no real money moves. The paper trade is recorded to your local trade history.

Paper mode is a good way to evaluate execution conditions on a market before committing real funds. Go through the full order flow, check the slippage estimate and signals, and only connect your wallet once you’re satisfied with the setup.
