Data Sources

Values are derived from two sources:

  1. On-Chain Contract Data: Immutable parameters fetched directly from the blockchain (via getSymbol(symbolId) orgetSymbols(start, size)).

  2. Hedger-Defined Parameters: Configurable values set by the market maker/hedger, subject to on-chain constraints.

Contract-Sourced Values

  • symbol_id: Unique identifier for the trading pair (e.g., 1 for BTCUSDT). Mapped directly from the contract’s symbolId.

  • name: Trading pair name (e.g., BTCUSDT).

  • is_valid: Indicates if the symbol is active for trading. Mapped from the contract’s isValid.

  • min_acceptable_quote_value: Minimum quote value (e.g., $120) required to open a position. Converted from the contract’s fixed-point value (e.g., 120000000000000000000120).

  • min_acceptable_portion_lf: Minimum portion of the liquidity fee (e.g., 0.003). Converted from the contract’s fixed-point value (e.g., 30000000000000000.003).

  • trading_fee: Fee charged per trade (e.g., 0.0006 or 0.06%). Derived from the contract’s tradingFee (e.g., 6000000000000000.0006).

Hedger-Defined Values

  • max_leverage: Maximum leverage allowed (e.g., 60x). Must be the contract’s Leverage (e.g., 60100).

  • max_notional_value: Maximum position size (e.g., $2,100,000). Must be the contract’s minAcceptableQuoteValue (e.g., 2100000120).

  • max_quantity: Maximum tradable quantity (e.g., 1000 BTC). No on-chain constraints.

  • max_funding_rate: Upper limit for funding rate (e.g., 200 ). Set by the hedger.

  • min_notional_value: Minimum position size (e.g., $100). Configured by the hedger.

  • hedger_fee_open/hedger_fee_close: Additional fees charged by the hedger (e.g., 0.0006).

  • rfq_allowed: Whether Request for Quote (RFQ) is enabled for the symbol.

Derived Values

  • symbol/asset: Base and quote assets (e.g., BTC and USDT). Parsed from the name field (e.g., BTCUSDTsymbol: BTC, asset: USDT).

  • price_precision: Number of decimal places for price (e.g., 1 → $100.1). Determined by the hedger based on market conventions.

  • quantity_precision: Number of decimal places for quantity (e.g., 3 → 0.001 BTC). Derived from min_acceptable_portion_lf (e.g., 0.003 implies 3 decimals).

  • lot_size: Always 0 (no minimum lot size enforced).
