In this issue, the editor will bring you about how to clean up the market data of different futures varieties for vnpy. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

Vnpy comes with a relatively simple market clean-up function, but in the removal of non-trading hours, not taking into account Saturdays and Sundays; and just generally gives a maximum time trading range, such as stock index futures without night plate, rebar ends at 11:00 in the evening, but the default is only to end at 02:30 this maximum trading time. So I wrote a method to clean it up in more detail according to different varieties.

You can insert this method directly into\ DataRecording\ runDataCleaning.py and replace the original method. You can also call it yourself.
