Installation

pip install opendeviationbar

Pre-built wheels: Linux (x86_64), macOS (ARM64), Python 3.13. Source build requires Rust toolchain and maturin.

Quick Start

from opendeviationbar import get_open_deviation_bars

# Fetch data and generate open deviation bars in one call
df = get_open_deviation_bars("BTCUSDT", "2024-01-01", "2024-06-30")

# Use with backtesting.py
from backtesting import Backtest, Strategy
bt = Backtest(df, MyStrategy, cash=10000, commission=0.0002)
stats = bt.run()

Output: pandas DataFrame with DatetimeIndex and OHLCV columns, compatible with backtesting.py.

API Overview

Function	Use Case
get_open_deviation_bars()	Date-bounded, auto-fetch
get_n_open_deviation_bars()	Exact N bars (ML training)
process_trades_polars()	Polars DataFrames (2-3x faster)
process_trades_chunked()	Large datasets (>10M trades)
populate_cache_resumable()	Long ranges (>30 days)
run_sidecar()	Real-time streaming sidecar

# Count-bounded (ML training)
from opendeviationbar import get_n_open_deviation_bars
df = get_n_open_deviation_bars("BTCUSDT", n_bars=10000)

# Polars (2-3x faster)
import polars as pl
from opendeviationbar import process_trades_polars
bars = process_trades_polars(pl.scan_parquet("trades.parquet"), threshold_decimal_bps=250)

# With microstructure features (57 columns: OFI, Kyle lambda, Hurst, etc.)
df = get_open_deviation_bars("BTCUSDT", "2024-01-01", "2024-06-30", include_microstructure=True)

# Real-time streaming sidecar
from opendeviationbar import run_sidecar, SidecarConfig
config = SidecarConfig(symbol="BTCUSDT", threshold_decimal_bps=250)
run_sidecar(config)

Designed for Claude Code
