Multiple stock visualization using backatrader_plotting

[石通斌]

Currently, I am backtesting 600 stocks using backtrader, but only 100 stocks have actual trades. When using backtrader_plotting for visualization, all stocks' charts are displayed, including those that have not been traded. This makes the generated file very large and I cannot focus on the stocks that have been traded. I want to only display the stocks that have been traded during the backtest process. This issue has been bothering me for a long time. Can anyone help me with how to achieve my requirement?

if __name__ == "__main__":
    all_data = pd.read_csv('/output_data_luky8_ocfps.csv')
    all_data = all_data[(all_data.datetime > '2018-01-01' ) & (all_data.datetime < '2022-01-01')]
    cerebro = bt.Cerebro()
    cerebro.addstrategy(MyStrategy)
    codes = np.unique(all_data.ts_code)
    random.shuffle(codes)

    for code in codes:
        feed = Addmoredata(dataname = get_data(all_data, code), name = code)
        cerebro.adddata(feed)

    startcash = 1000000
    cerebro.broker.setcash(startcash) 
    cerebro.broker.setcommission(commission=0.001) 
    cerebro.addanalyzer(bt.analyzers.SharpeRatio, _name = 'SharpeRatio')
    cerebro.addanalyzer(bt.analyzers.DrawDown, _name='DW')
    cerebro.addanalyzer(bt.analyzers.TimeReturn, timeframe=bt.TimeFrame.Years)
    cerebro.addanalyzer(TradeAnalyzer)

    #return_df = pd.DataFrame(cerebro.addanalyzer(bt.analyzers.TimeReturn, timeframe=bt.TimeFrame.Days).items(), columns=['Date', 'DateValue'])
    results = cerebro.run()
    strat = results[0]
    print('SR:', strat.analyzers.SharpeRatio.get_analysis())
    print('DW:', strat.analyzers.DW.get_analysis())


    tret_analyzer = strat.analyzers.getbyname('timereturn')
    print(tret_analyzer.get_analysis())

    portvalue = cerebro.broker.getvalue()
    pnl = portvalue - startcash
    cerebro.addwriter(bt.WriterFile, out = 'bt_log.csv', csv =True)

    
    b = Bokeh(style =  'bar', plot_mode='single', scheme=Tradimo())
    cerebro.plot(b)
