Market data on Polyester provides a real-time view into price discovery, liquidity, and trading activity, without exposing individual trader positions or compromising fair market behavior.
What Market Data Represents on Polyester
Market data reflects the collective activity of the exchange, not the state of individual accounts.
It includes:
- Current prices and historical price movement
- Liquidity available in the order book
- Completed trades and volumes
- Aggregate market activity across pairs
Market data is produced by the PolyEngine, which processes orders, matches trades, and streams updates continuously to the interface and external consumers.
Real-Time vs Delayed Data
Polyester intentionally exposes different layers of market data with different visibility guarantees.
- Prices, candles, and completed trades update in real time
- L1 (top-of-book) and L2 (aggregated depth) are visible in real time
- L3 (individual order-level data) is delayed by default
This structure ensures that all traders see accurate market conditions while reducing the risk of order-level exploitation or position hunting.
Highly qualified participants who materially improve market quality may gain access to real-time L3 data. See Order Book for details.
Transparency Without Account-Level Exposure
All market activity on Polyester is verifiable, but not everything is attributable.
Everyone can always observe:
- When trades occur
- At what price and size
- How liquidity moves through the book
No one can observe:
- Which account placed a trade
- How large a trader’s remaining position is
- How balances change for other users’ Unified Trading Account
This approach preserves market fairness while still allowing independent analysis of liquidity, volume, and price formation.
Where Market Data Is Displayed
Market data appears across the platform in multiple places:
- Markets page for pair-level statistics
- Spot Trading page for live interaction
- Widgets such as the ‘order book’, ‘depth chart’, and ‘market trades’
- Polyester Scan for on-chain trade visibility
Each surface shows the same underlying data, adapted for different use cases.
Verifiability and Auditability
Completed trades are recorded on-chain and can be inspected through Polyester Scan.
While trader identities and per-account balances remain private, the existence, price, and size of trades are always observable. This allows third parties to independently verify that trading activity is real, consistent, and backed by actual settlement.
