从BATS交易所获取空头头寸
Getting short volume from BATS
In my last post I have gone through the steps needed to get the short volume data from the BATS exchange. The code provided was however of the quick-n-dirty variety. I have now packaged everything to bats.py module that can be found on google code. (you will need the rest of the TradingWithPython library to run bats.py)

dl = bats.BATS_Data('C:\batsData') # init with directory to save data
