trading-data-py

Python client for the TradeInsight Trading Data Service API. Provides a Ticker class with a history() method that returns a pandas DataFrame with yfinance-compatible column names.

Installation

pip install trading-data-py

Or install from source:

git clone https://github.com/tradeinsight/trading-data-py.git
cd trading-data-py
pip install -e .

Quick Start

Set your API key in the environment:

export TIDATA_API_KEY=your_key_here

Then use the client:

from tidata.tifinance import Ticker

# API key is read from TIDATA_API_KEY env var automatically
t = Ticker("AAPL")

# Adjusted prices (yfinance-compatible)
df = t.history(start="2024-01-01", end="2024-12-31")
print(df.head())
#                  Open        High         Low       Close      Volume  Dividends  Stock Splits
# Date
# 2024-01-02  184.210...  185.880...  183.430...  185.200...  79047200.0        0.0           0.0

# Raw (unadjusted) prices — adds an "Adj Close" column, like yfinance
df_raw = t.history(start="2024-01-01", end="2024-12-31", auto_adjust=False)

yfinance drop-in

Ticker.history() mirrors yfinance for the daily-OHLCV case:

from tidata.tifinance import Ticker, download

# period shorthands: 1d 5d 1mo 3mo 6mo 1y 2y 5y 10y ytd max
df = Ticker("AAPL").history(period="1y")

# non-zero dividends / splits over full available history (period="max")
divs = Ticker("AAPL").dividends
spl = Ticker("AAPL").splits

# bulk download — flat frame for one ticker, column MultiIndex for many
one = download("AAPL", period="6mo")
many = download("AAPL MSFT", period="6mo")   # columns: (field, ticker)

Behaviour notes

• On API errors, history() logs a warning and returns an empty DataFrame (yfinance behaviour). Pass raise_errors=True to raise the typed exception instead.
• period="max" requests full available history (from a 1900-01-01 floor), not a fixed window.
• Only interval="1d" is currently supported.
• The index is a tz-naive DatetimeIndex named Date.

Configuration

Exceptions

All exceptions inherit from APIError which exposes .code and .message.
