FMZ Trading API Notes on Market Data, Orders, and Fault Tolerance

Article FMZ forum · Author: 发明者量化-小小梦

Summary

This evolving FAQ collects practical notes for building and operating trading strategies on the FMZ platform. It explains why ticker and order-book snapshots can differ, how order queries distinguish unfinished from completed orders, and how contract selection affects futures market data. It also describes order-volume conventions, market versus limit order parameters, and the need to account for platform-specific contract and spot-market units.

Several entries address data and implementation pitfalls: exchanges may return different amounts of historical candles, indicator calculations can vary across libraries or platforms, and API requests can fail in ways that require strategy-level retries or filtering. The page also discusses time-zone and clock synchronization issues, precision limits, and charting or debugging tools. These are operational explanations rather than a trading strategy, and the FAQ is incomplete and platform-specific. It offers troubleshooting guidance but no systematic performance evidence or universal guarantee that behavior is identical across exchanges.

Key ideas

  • Ticker and order-book values may differ because they are collected at different times.
  • Completed orders may require a separate order lookup, depending on platform support.
  • Futures data depends on selecting the intended contract before requesting bars.
  • Order sizes and market-order parameters vary by product type and exchange.
  • API failures and differences in indicator calculations may require strategy-level handling.
