How to read data feeds of more than two years?

[Nel]

Hi everyone, I am new to Backtrader and have faced an issue.
I need to load a 5-years historical data using GenericCSVData. However, the output only shows the last two years of data.
I assigned "fromdate" to 2015 and "todate" to 2020, but the output prints data from 2018 till 2020.

Here is how I read the data feed:

datapath = os.path.join(modpath, 'data', 'yahoo_AAPL_2015_2020.txt')

data = btfeeds.GenericCSVData(
dataname= datapath,

fromdate=datetime.datetime(2015, 1, 1),
todate=datetime.datetime(2020, 1, 1),

nullvalue=0.0,

dtformat=('%Y-%m-%d'),

datetime=0,
high=1,
low=2,
open=3,
close=4,
volume=5,
openinterest=-1)

Any help would be appreciated!

Would need to see your data. Maybe try removing fromdate & todate arguments. That will use all available data by default

@hghhgghdf-dfdf I did what you suggested but it didn't work.
Data is a text file as below:

Could you post all of your code together please?

[Nel]

@run-out Yes, here is the code:

from __future__ import (absolute_import, division, print_function,
                        unicode_literals)

import datetime  # For datetime objects
import os.path  # To manage paths
import sys  # To find out the script name (in argv[0])

# Import the backtrader platform
import backtrader as bt
import backtrader.feeds as btfeeds


# Create a Stratey
class TestStrategy(bt.Strategy):

    def log(self, txt, dt=None):
        ''' Logging function for this strategy'''
        dt = dt or self.datas[0].datetime.date(0)
        print('%s, %s' % (dt.isoformat(), txt))

    def __init__(self):
        # Keep a reference to the "close" line in the data[0] dataseries
        self.dataclose = self.datas[0].close

    def next(self):
        # Simply log the closing price of the series from the reference
        self.log('Close, %.2f' % self.dataclose[0])



if __name__ == '__main__':
    # Create a cerebro entity
    cerebro = bt.Cerebro()
    
    cerebro.addstrategy(TestStrategy)

    # Datas are in a subfolder of the samples. Need to find where the script is
    # because it could have been called from anywhere
    modpath = os.path.dirname(os.path.abspath(sys.argv[0]))
    datapath = os.path.join(modpath, 'data', 'yahoo_AAPL_2015_2020.txt')

    data = btfeeds.GenericCSVData(
    dataname= datapath,
    reverse = False,
    
    fromdate=datetime.datetime(2015, 1, 1),
    todate=datetime.datetime(2020, 1, 1),


    nullvalue=0.0,

    dtformat=('%Y-%m-%d'),

    datetime=0,
    high=1,
    low=2,
    open=3,
    close=4,
    volume=5,
    openinterest=-1

    # Add the Data Feed to Cerebro
    cerebro.adddata(data)

    # Set our desired cash start
    cerebro.broker.setcash(100000.0)

    # Print out the starting conditions
    print('Starting Portfolio Value: %.2f' % cerebro.broker.getvalue())

    # Run over everything
    cerebro.run()

    # Print out the final result
    print('Final Portfolio Value: %.2f' % cerebro.broker.getvalue())

Your code is fine. I just ran it with your data above, what's there anyway. And it prints all of it and also allows for changed dates.

You should try it on a different data file. Or perhaps your terminal is only displaying the last 'n' results? Try reducing the date range.

[Nel]

@run-out Thanks! Is there any way that I can save the output of the code to check if it reads all data or not? In this way I can make sure that it's terminal issue.

[run-out]

Just try it in smaller date ranges, maybe try one year at a time.
