Intraday Trading: Model&Strategy Testing¶

Introduction¶

Intraday Trading is designed to test models and strategies, which help users to check the performance of a custom model/strategy.

Note

Intraday Trading uses Order Executor to trade and execute orders output by Portfolio Strategy. Order Executor is a component in Qlib Framework, which can execute orders. VWAP Executor and Close Executor is supported by Qlib now. In the future, Qlib will support HighFreq Executor also.

Example¶

Users need to generate a prediction score`(a pandas DataFrame) with MultiIndex<instrument, datetime> and a `score column. And users need to assign a strategy used in backtest, if strategy is not assigned, a TopkDropoutStrategy strategy with (topk=50, n_drop=5, risk_degree=0.95, limit_threshold=0.0095) will be used. If Strategy module is not users’ interested part, TopkDropoutStrategy is enough.

The simple example of the default strategy is as follows.

from qlib.contrib.evaluate import backtest
# pred_score is the prediction score
report, positions = backtest(pred_score, topk=50, n_drop=0.5, verbose=False, limit_threshold=0.0095)

To know more about backtesting with a specific Strategy, please refer to Portfolio Strategy.

To know more about the prediction score pred_score output by Forecast Model, please refer to Forecast Model: Model Training & Prediction.

Prediction Score¶

The prediction score is a pandas DataFrame. Its index is <datetime(pd.Timestamp), instrument(str)> and it must contains a score column.

A prediction sample is shown as follows.

  datetime instrument     score
2019-01-04   SH600000 -0.505488
2019-01-04   SZ002531 -0.320391
2019-01-04   SZ000999  0.583808
2019-01-04   SZ300569  0.819628
2019-01-04   SZ001696 -0.137140
             ...            ...
2019-04-30   SZ000996 -1.027618
2019-04-30   SH603127  0.225677
2019-04-30   SH603126  0.462443
2019-04-30   SH603133 -0.302460
2019-04-30   SZ300760 -0.126383

Backtest Result¶

The backtest results are in the following form:
