Public API for TraderNet

tradernet-sdk

Public Python API for TraderNet

Installation

Installing tradernet with pip is straightforward:
python -m pip install tradernet-sdk
Instead of python you can use here and further pypy3 depending on your preferences.

Usage

Import the client library into your script:
from tradernet import TraderNetAPI
Initialize it with your credentials:
api = TraderNetAPI('public_key', 'private_key', 'login', 'passwd')
or create a config file tradernet.ini with the following content:

[auth]
public   = public_key
private  = private_key
login    = login
password = passwd

and initialize the client with api = TraderNetAPI.from_config('tradernet.ini')
Call any of its public methods, for example:
api.user_info()

How to trade

Usage of the trading interface is similar to common API. Import and instantiate Trading class:

from tradernet import Trading


order = Trading.from_config('tradernet.ini')

Now let's buy 1 share of FRHC.US at the market price:

order.buy('FRHC.US')

Advanced techniques

One can import the core class to write their own methods:

from tradernet import TraderNetCore


class MyTNAPI(TraderNetCore):
    pass

This allows using sophisticated request methods for TN API like TraderNetCore.authorized_request.

One can have several instances of the API serving different purposes:

config = TraderNetCore.from_config('tradernet.ini')
order = Trading.from_instance(config)

The instance config stores the credentials, and order can be used to trade and may be destroyed after trades completed while config is still can be used to instantiate other classes.

Websockets

Websocket API can be accessed via another class TraderNetWSAPI. It implements asynchronous interface for TraderNet API, and its usage is a bit more complicated:

from tradernet import TraderNetCore, TraderNetWSAPI


async def main() -> None:
    api = TraderNetCore.from_config('tradernet.ini')
    async with TraderNetWSAPI(api) as wsapi:  # type: TraderNetWSAPI
        async for quote in wsapi.market_depth('FRHC.US'):
            print(quote)

Legacy API

The library also has the legacy PublicApiClient.py which provides almost the same functionality as most of TraderNet users used to:

from tradernet import NtApi


pub_ = '[public Api key]'
sec_ = '[secret Api key]'
cmd_ = 'getPositionJson'
res = NtApi(pub_, sec_, NtApi.V2)
print(res.sendRequest(cmd_))

The only difference is that one doesn't have to decode the content of the response as before.

Options

The notation of options in TraderNet now can easily be deciphered:

from tradernet import TraderNetOption


option = TraderNetOption('+FRHC.16SEP2022.C55')
print(option)  # FRHC.US @ 55 Call 2022-09-16

or the scary old notation:

from tradernet import DasOption


option = DasOption('+FRHC^C7F45.US')
print(option)  # FRHC.US @ 45 Call 2022-07-15

Wrapping market data

Another feature is to get handy pandas.DataFrame objects with market data:

from pandas import DataFrame
from tradernet import TraderNetSymbol, TraderNetAPI


api = TraderNetAPI('public_key', 'private_key', 'login', 'passwd')
symbol = TraderNetSymbol('AAPL.US', api).get_data()
market_data = DataFrame(
    symbol.candles,
    index=symbol.timestamps,
    columns=['high', 'low', 'open', 'close']
)
print(market_data.head().to_markdown())
# | date                |     high |      low |     open |    close |
# |:--------------------|---------:|---------:|---------:|---------:|
