1. Download historical data for backtesting

   $ python -m basana.external.binance.tools.download_bars -c BCH/USDT -p 1h -s 2021-12-01 -e 2021-12-26 -o binance_bchusdt_hourly.csv
   $ python -m basana.external.binance.tools.download_bars -c CVC/USDT -p 1h -s 2021-12-01 -e 2021-12-26 -o binance_cvcusdt_hourly.csv
   

2. Run the backtest

   $ python -m samples.backtest_pairs_trading
   

The following example demonstrates how to maintain a synchronized local copy of a Binance order book using Basana's event-driven architecture. It initializes the order book from a REST API snapshot, then continuously updates it with real-time diffs from a WebSocket stream while periodically verifying consistency against fresh snapshots to handle potential synchronization issues.

Use the following command to run the example:

$ python -m samples.binance_order_book_mirror

The mirroring code can be found here.
