Retrieving Binance Perpetual Contract Precision from Exchange Rules

Summary

This note describes a utility for setting price and quantity precision for Binance perpetual contracts. It queries Binance’s derivatives exchange information endpoint, searches the returned symbol records for each configured instrument, and reads the price tick size and minimum quantity from the corresponding filters. The decimal places in those values are then used to configure the exchange precision.

The note’s main practical lesson is that exchange metadata can be used to automate instrument settings, but the author reports abandoning this approach because Binance’s published trading rules were often not updated promptly. It provides no comparison, test results, or fallback procedure. The precision derived from minimum quantity may also not capture every sizing constraint, so the values should be checked against current contract rules before relying on them.

Key ideas

• The utility retrieves symbol and filter data from Binance’s derivatives exchange information endpoint.
• It matches configured contracts to returned symbols before reading their trading filters.
• Price precision is inferred from tick size, while quantity precision is inferred from minimum quantity.
• The author discontinued the approach because the exchange rules were sometimes stale.
