Language: Python 3.11+ | License: GPL-3.0 | Price: Free | GitHub Stars: ~48.1K

Key Features

  • Complete trading pipeline — backtest, dry-run (paper trade), and live trade
  • FreqUI — web-based dashboard for monitoring and control
  • Telegram integration — manage your bot remotely
  • FreqAI — built-in machine learning module for strategy optimization
  • Hyperopt — automated hyperparameter tuning (stoploss, ROI, indicators)
  • Multi-exchange support — Binance, Kraken, OKX, Bybit, Gate.io, HTX, and more
  • Spot and futures trading
  • Edge positioning for dynamic stoploss calculation
  • Comprehensive performance reports with profit/loss, drawdown, trade analysis

Strategy Example

from freqtrade.strategy import IStrategy, DecimalParameter
import talib.abstract as ta

class SampleStrategy(IStrategy):
    minimal_roi = {"0": 0.04}
    stoploss = -0.10
    timeframe = '5m'

    def populate_indicators(self, dataframe, metadata):
        dataframe['rsi'] = ta.RSI(dataframe, timeperiod=14)
        return dataframe

    def populate_entry_trend(self, dataframe, metadata):
        dataframe.loc[dataframe['rsi'] < 30, 'enter_long'] = 1
        return dataframe

    def populate_exit_trend(self, dataframe, metadata):
        dataframe.loc[dataframe['rsi'] > 70, 'exit_long'] = 1
        return dataframe

Strategies use a three-method pattern: define indicators, define entry conditions, define exit conditions. Freqtrade handles everything else — order execution, risk management, logging, and reporting.

Running a Backtest

# Download historical data from an exchange
freqtrade download-data --timerange 20200101-20210101 -t 5m

# Run backtest
freqtrade backtesting --strategy SampleStrategy --timerange 20200101-20210101

# Optimize parameters
freqtrade hyperopt --strategy SampleStrategy --hyperopt-loss SharpeHyperOptLoss -e 500

Backtest output includes total profit, trade count, win rate, max drawdown, Sharpe ratio, and per-trade breakdown.

Data Sources

  • Exchange historical data — downloaded directly from supported exchanges for free
  • Multiple timeframes — 1m, 5m, 15m, 1h, 4h, 1d, and more
  • Local storage in JSON or HDF5 format
  • No external data subscription needed — exchanges provide the data

This is a major advantage over traditional backtesting frameworks that require you to source data separately.

Who Should Use Freqtrade?

Freqtrade is the obvious choice for crypto traders who want an all-in-one solution: backtest, optimize, paper trade, and go live. The combination of Hyperopt, FreqAI, and multi-exchange support makes it uniquely powerful in the crypto space.

If you trade stocks, forex, or other asset classes, look at QuantConnect or Backtrader. If you want something simpler for one-off backtests, try Backtesting.py. If you need raw speed for research, check VectorBT.
