Using FMZ to Query and Trade Vertex DEX Markets

Summary

This hands-on guide describes connecting FMZ to Vertex, a decentralized exchange with spot and perpetual markets. It explains wallet and subaccount configuration, the use of a wallet or delegated signing key, and the need to account for USDC costs on withdrawals and transfers. The examples demonstrate retrieving market metadata, order-book depth, recent trades, candles, funding rates, account limits, and linked signer information. They also cover placing and cancelling limit orders, checking positions, and constructing trigger orders with required nonce and expiration values.

The article includes a simple threshold strategy that compares the current price with an initial reference price, then opens a long or short when the move exceeds a configured ratio. It shows sample backtest and live use, but gives no systematic performance analysis; the author warns that the strategy is for learning and testing. The guide also notes that API position averages and profit figures can differ from the exchange interface, and that its integration requires a recent platform runtime. Operational details and the brief strategy example should not be treated as evidence of profitability or reliable risk control.

Key ideas

• Vertex integration supports querying market data and account information, as well as managing spot and perpetual orders through FMZ.
• Wallet configuration includes a wallet address, signing key, and a subaccount tag.
• Trigger orders require generated nonce and expiration values, and some account operations consume USDC.
• The example strategy opens long or short positions when price moves beyond a threshold from its initial reference.
• The article reports no robust strategy evaluation and notes discrepancies between API and interface position statistics.
