The article outlines a real-time ETH/USDT trading framework that combines LightGBM for tabular inputs with a Transformer for sequential data. It describes WebSocket market-data ingestion, minute-bar construction, technical, statistical, volume, and…

This reference compares order and position query behavior across 21 futures venues. For order retrieval, it records whether an endpoint is paginated, whether the request path or parameters vary by contract type or settlement currency, and when multiple…

The article explains why strong historical backtest results may fail in live trading, especially when strategy design unintentionally uses information that would not have been available at the time. It presents two ways to assess strategies with limited…

The document explains how strategy developers can attach metadata to rental registration codes and read it inside a strategy to set different usage limits for different customers. A strategy can map metadata values to operating tiers, then check account…

This troubleshooting note asks how to submit a Binance withdrawal request through an API. It focuses on adding a timestamp and generating an HMAC-SHA256 signature over request parameters. The author tries sending the parameters and signature in the request…

The document explains how Bayesian decision theory assigns an observation to the class with the largest posterior probability. It separates the posterior into a class-conditional likelihood and a prior class probability. The prior can be estimated from class…

The speech explains how option-focused funds seek returns by assessing the risk environment, comparing implied option prices with estimates of risk, and spreading trades across contracts and products. It frames options as insurance: sellers may collect…

This article describes an API workflow for market making on BitMEX perpetual contracts. It recommends using WebSockets for market updates and REST requests for account information, while noting that order book and account streams can be incomplete or delayed…
