Tradier REST + Streaming API client

tradier_api_client

Python client for the Tradier Brokerage API (REST) plus optional streaming helpers.

This repo is intended to give you a lightweight, script-friendly way to call Tradier endpoints (quotes, options, orders, account data) using a single RestClient.

Note: Some examples below are adapted from tests/real_data.py which is intended for local use with a real API key. Don’t commit keys.

Installation

From source (editable):

python -m pip install -U pip
python -m pip install -e .

Regular install (from the cloned repo):

python -m pip install .

---

Authentication

Set your Tradier API key in an environment variable.

Windows (cmd.exe)

set API_KEY=your_key_here

macOS/Linux

export API_KEY=your_key_here

---

Quick start

Create a RestClient

The tests create a client like this:

import os
from tradier_api_client import RestClient

client = RestClient(
    base_url="https://sandbox.tradier.com/v1",  # use https://api.tradier.com/v1 for production
    api_key=os.environ.get("API_KEY"),
    verbose=True,
)

print("Account:", client.account_number)

---

Common REST examples

1) Quotes

quotes = client.get_quotes(["AAPL", "MSFT"])
print(quotes)

2) Historical quotes

history = client.get_historical_quotes("AAPL", start="1979-01-01")
print(history)

3) Option expirations + option chains

expirations_resp = client.get_option_expirations("AAPL")
expirations = expirations_resp.get("expirations", {}).get("date", [])
print(expirations)

if expirations:
    chain = client.get_option_chains("AAPL", expirations[0])
    print(chain)

4) Options helper workflow (OCC symbols)

The repo includes an OptionsWrapper and helper utilities used by tests/real_data.py.

from tradier_api_client.rest.extensions.options import (
    OptionsWrapper,
    parse_occ,
    filter_options_occ,
    filter_for_tradable_options_strike_plus_bid,
)

ow = OptionsWrapper(client)
occ_symbols = ow.get_call_options_occ_symbols_list("AAPL")

# Parse OCC symbols into structured info
parsed = parse_occ(occ_symbols)

# Filter by expiration window and strike constraints (example)
filtered_occ = filter_options_occ(options=occ_symbols, exp_end="2027-08-30", exp_start="2027-01-01")

# Quote options and filter for tradable candidates
quotes = client.get_quotes(filtered_occ)
tradable = filter_for_tradable_options_strike_plus_bid(
    quotes=quotes,
    occ_symbols=filtered_occ,
    target_price=5.5,
)
print(tradable)

5) Account endpoints (example: gain/loss)

gain_loss = client.get_gain_loss(client.account_number)
print(gain_loss)

---

Orders

The order helpers live under tradier_api_client.rest.extensions.orders.

Equity limit buy (example)

from tradier_api_client.rest.extensions.orders import equity_limit

order_request = equity_limit(
    symbol="AAPL",
    side="buy",
    quantity=1,
    price=150,
    duration="gtc",
)

resp = client.place_order(client.account_number, order_request)
print(resp)

Read / cancel orders

orders = client.get_orders(client.account_number)
print(orders)

# If you have an order id:
# order = client.get_order(client.account_number, "12345678")
# print(order)

# cancel_resp = client.cancel_order(client.account_number, "12345678")
# print(cancel_resp)

---

Streaming (optional)

If you want real-time market data, use StreamingClient (websocket streaming). This is optional; the REST client works without it.

The StreamingClient constructor takes in the main API key that you also use REST calls. Additional API keys and account numbers are meant for advanced and serious trading.

The StreamingClient instance for markert data streaming takes a list of symbols and event types in the start_listening call.

Authentication

StreamingClient uses the same API_KEY environment variable shown above.

Basic example: connect and print events

import os
import time



from tradier_api_client import RestClient
from tradier_api_client.streaming import StreamingClient  # adjust if your module path differs

def on_message(msg: dict) -> None:
    # The payload shape depends on the event type (quotes, trades, etc.)
    print(msg)

client = StreamingClient(main_api_key=os.environ.get("API_KEY"),
                         base_url="https://sandbox.tradier.com/v1",
                         stream_base_url="wss://sandbox-ws.tradier.com/v1",
                         main_account_id=os.environ.get("ACCOUNT_ID"),
                         events_callback=on_message, stream_type="account")
client.start_listening()
time.sleep(60)  # listen for 60 seconds
client.stop()

Running tests (local repo)

This project includes tests/integration scripts under tests/.

• Some scripts (like tests/real_data.py) may call live/sandbox endpoints and require API_KEY.
• The tests/ folder is not intended to be installed with the client distribution.

To run tests locally:

python -m pip install -U pytest
pytest -q

---

Notes / troubleshooting

• Sandbox vs production: use https://sandbox.tradier.com/v1 for paper testing and https://api.tradier.com/v1 for production.
• If you see authentication errors, confirm API_KEY is set in the environment used by your Python interpreter.
