CSI300_BENCH = "SH000300"
# Benchmark is for calculating the excess return of your strategy.
# Its data format will be like **ONE normal instrument**.
# For example, you can query its data with the code below
# `D.features(["SH000300"], ["$close"], start_time='2010-01-01', end_time='2017-12-31', freq='day')`
# It is different from the argument `market`, which indicates a universe of stocks (e.g. **A SET** of stocks like csi300)
# For example, you can query all data from a stock market with the code below.
# ` D.features(D.instruments(market='csi300'), ["$close"], start_time='2010-01-01', end_time='2017-12-31', freq='day')`
