This Chinese-language forum thread raises an implementation issue in quantitative trading software: a contract can be dynamically subscribed to through the engine and strategy code, yet its market data may not arrive at the strategy. The original poster says…

The discussion explains a timing issue in CTA strategies using the CTP interface: order status updates may arrive before trade updates, and the position is updated with the trade notification. A strategy that reacts to a fully filled order inside its order…

This brief forum exchange answers whether data sources for VeighNa, an algorithmic trading platform, are free. One user reports authentication errors while trying credentials from an example configuration for a Tushare integration. A respondent explains that…
The article explains why futures research often uses constructed continuous series: individual contracts expire, so a longer history requires rules for selecting and joining successive contracts. A direct splice can create an artificial price gap at a roll,…
This post describes a macOS setup problem connecting VeighNa’s CTP interface to a futures broker. The reported symptoms are an initial 4040 error followed by repeated 4097 errors. The author says the broker’s troubleshooting materials targeted Windows, while…
