你好！
想请教一下，在你的base_reader.py中load方法，从csv或者mongodb读取之后最终返回的是什么内容？是dataframe？dict？

如果全A选股，需要3000多个mongodb连接？

hi chandler cjy
do you have a complete CSV reader backtesting example?
I have tried to modify your module to trial stock backtesting with downloaded CSV data.
but not work, error msg below:

AttributeError Traceback (most recent call last)
in
----> 1 go.sunny(show_process=True)

AttributeError: 'CSVReader' object has no attribute 'sunny'

can you please suggest , how to fix this issue?
thanks a lot,

import OnePy as op
from OnePy.custom_module.cleaner_sma import SMA

class SmaStrategy(op.StrategyBase):

def __init__(self):

    super().__init__()
    self.sma1 = SMA(3, 40).calculate
    self.sma2 = SMA(5, 40).calculate

def handle_bar(self):
    for ticker in self.env.tickers:

        if self.sma1(ticker) > self.sma2(ticker):

            self.buy(100, ticker, takeprofit=15,
                     stoploss=100)
        else:
            self.sell(100, ticker)

TICKER_LIST = ['^DJI'] # 多品种
INITIAL_CASH = 20000
FREQUENCY = 'D'
START, END = '2015-08-07', '2018-08-07'

实例化策略，会自动添加到env.strategies中

SmaStrategy()

如果用CSV回测,注意csv文件名为name_frequency，同时要将下面MongoDB回测注释掉

go = op.data_readers.CSVReader('C:\Users\jarod\OnePy-master\data\', file_name='000001', ticker='^DJI')
#go = op.backtest.stock(TICKER_LIST, FREQUENCY, INITIAL_CASH, START, END) # 设置好股票回测的基本配置
#go = op.backtest.stock(TICKER_LIST, FREQUENCY, INITIAL_CASH, START, END)

go.sunny(show_process=True)

你好，我已经pip安装了dataclasses模块了，但是仍然显示

ModuleNotFoundError: No module named 'dataclasses'
Process finished with exit code 1

请问这个如何解决。

谢谢！

您好,非常感谢您的代码,我对py还不熟悉,类这关卡一直没过... 我运行案例里面的csv_to_MongoDB.py 报错
