Terminal Overview
The Polyblock terminal is your command center for prediction market trading. Learn about each component and how to use them effectively.
Layout Overview
The terminal is divided into three main sections designed for efficient trading:
Left Panel: Price Chart
Displays historical price movements and helps you analyze market trends before making trading decisions.
Center Panel: Order Book
Shows all active buy and sell orders in the market, giving you insight into supply, demand, and liquidity.
Right Panel: Trading Interface
Where you execute trades, view your positions, and manage orders.
Typical workflow
Most manual sessions follow the same path: pick the asset and timeframe, confirm the market question matches the candle you want to trade, read the chart for context, then use the order book to judge liquidity before you size an order. After you send an order, watch the open orders list for partial fills and verify your position line matches what you expect.
Before you click buy or sell
Check YES and NO prices together—they should roughly sum to about $1.00 before fees. Wide deviations can mean stale quotes or a dislocated book; slow down and confirm the best bid and ask on both sides. For a deeper read, continue to Understanding Markets and Reading the Order Book.
After you are filled
Your position panel should show average entry, size, and mark-to-mid unrealized PnL. If the market is close to resolution, decide whether to hold through resolution or flatten first; resolution pays winning shares at $1.00 each, while exits before resolution are always at prevailing bids and asks.
Chart Panel
The chart displays price history for the selected market with color-coded candles:
Green Candles
Indicate markets that resolved YES — the predicted event occurred.
Red Candles
Indicate markets that resolved NO — the predicted event did not occur.
Order Book
The order book displays all pending orders in the market:
Bid Side (Green)
Shows buy orders — traders willing to buy at these prices. The highest bid is the best price you can sell at immediately.
Ask Side (Red)
Shows sell orders — traders willing to sell at these prices. The lowest ask is the best price you can buy at immediately.
Spread
The difference between best bid and best ask. A tighter spread indicates better liquidity and lower trading costs.
Trading Panel
The trading panel is where you execute all your trades:
Market Info
Shows the current market question, YES/NO prices, and your existing position.
Order Entry
Select BUY or SELL, choose YES or NO outcome, enter amount and price (for limit orders).
Position Display
View your current position size, average entry, and unrealized profit/loss.
Open Orders
List of your pending limit orders with options to cancel.
Live data and refresh
The terminal streams order book and price updates over WebSockets. If your connection drops briefly, the UI typically reconnects; if prices look frozen, refresh the page after checking your network. You should not need to manage RPC endpoints or wallet popups—custodial execution is handled server-side once you confirm in the panel.
Fast markets (especially 5-minute windows) punish hesitation. Prefer limit orders when you need a specific price, and market orders only when you accept the displayed top-of-book trajectory. See Order Types for trade-offs on slippage and fees.
