Today (August 14, 2020), wondertrader released version v0.5.1, and wtpyv0.5.1 was released simultaneously

Wondertrader has made the following changes in v0.5.1:

  • When the real offer engine (CTA, HFT, SEL) is started, it outputs the policy list and transaction channel list to a configuration file to facilitate the monitoring service to read and view
  • A new event notification component, eventnotifier, is added. It is mainly used to send transaction return and order return to the specified receiver through UDP channel. It will be extended to other data to be monitored in the future
  • In the backtesting engine, the data records (transactions, signals, positions closed and funds) generated during the backtesting process are not written into the file during the backtesting process, but are uniformly written into the file after the backtesting is completed
  • Improved the processing of stock index option IO by contract code standardization in the system
