Getting Data

To download the data use tv.get_hist method.

It accepts following arguments and returns pandas dataframe

(symbol: str, exchange: str = 'NSE', interval: Interval = Interval.in_daily, n_bars: int = 10, fut_contract: int | None = None, extended_session: bool = False) -> DataFrame)

for example-

# index
nifty_index_data = tv.get_hist(symbol='NIFTY',exchange='NSE',interval=Interval.in_1_hour,n_bars=1000)

# futures continuous contract
nifty_futures_data = tv.get_hist(symbol='NIFTY',exchange='NSE',interval=Interval.in_1_hour,n_bars=1000,fut_contract=1)

# crudeoil
crudeoil_data = tv.get_hist(symbol='CRUDEOIL',exchange='MCX',interval=Interval.in_1_hour,n_bars=5000,fut_contract=1)

# downloading data for extended market hours
extended_price_data = tv.get_hist(symbol="EICHERMOT",exchange="NSE",interval=Interval.in_1_hour,n_bars=500, extended_session=False)

Cloud Usage

You might face some problem while using TvDatafeed in cloud because of selenium. For that make sure to create the app dir before initializing TvDatafeed

from tvDatafeed import TvDatafeed,Interval
app_dir = os.mkdir(os.path.join(os.path.expanduser("~"), ".tv_datafeed/"))
if not os.path.exists(app_dir):
    os.mkdir(app_dir)

tv = TvDatafeed()

# your code goes here

This will only work without username and password. You will be able to download most of the data without logging in

Read this before creating an issue

Before creating an issue in this library, please follow the following steps.

1. Search the problem you are facing is already asked by someone else. There might be some issues already there, either solved/unsolved related to your problem. Go to issues page, use is:issue as filter and search your problem.
2. If you feel your problem is not asked by anyone or no issues are related to your problem, then create a new issue.
3. Describe your problem in detail while creating the issue. If you don't have time to detail/describe the problem you are facing, assume that I also won't be having time to respond to your problem.
4. Post a sample code of the problem you are facing. If I copy paste the code directly from issue, I should be able to reproduce the problem you are facing.
5. Before posting the sample code, test your sample code yourself once. Only sample code should be tested, no other addition should be there while you are testing.
6. Have some print() function calls to display the values of some variables related to your problem.
7. Post the results of print() functions also in the issue.
8. Use the insert code feature of github to inset code and print outputs, so that the code is displyed neat. !
9. If you have multiple lines of code, use tripple grave accent ( ``` ) to insert multiple lines of code. Example:
