sixtysix 0.0.8

Framework for building trading strategies and technical indicators

SixtySix

Python SDK and CLI for building and deploying automated trading strategies on sixtysix.pro.

The SDK lets you write strategies and indicators in Python — they are picked up automatically by the backend, which handles data feeds, backtesting, live execution, and the charting UI.

The CLI manages the backend: pull the Docker image, authenticate, run backtests from the terminal, or deploy to a cloud VPS with one command.

Quick Start — Strategy

from sixtysix import strategy, computed, param, persistent, Line

@strategy(name='sma_crossover', display_name='SMA Crossover', category='Trend Following')
class SMACrossover:
    fast = param.number(default=20, min=5, max=100)
    slow = param.number(default=50, min=10, max=200)

    @computed
    def fast_sma(self, df):
        return df['close'].rolling(self.fast).mean()

    @computed
    def slow_sma(self, df):
        return df['close'].rolling(self.slow).mean()

    def plot(self, df):
        return [
            Line(y=self.fast_sma, color='#3b82f6', legend='Fast'),
            Line(y=self.slow_sma, color='#f97316', legend='Slow'),
        ]

    def on_bar(self, df):
        if self.position.is_flat and self.ta.crossover(self.fast_sma, self.slow_sma):
            return self.buy(reason='Golden cross')
        if self.position.is_long and self.ta.crossunder(self.fast_sma, self.slow_sma):
            return self.close(reason='Death cross')

Quick Start — Indicator

from sixtysix import indicator, param, Line, Fill

@indicator(name='bollinger_bands', display_name='Bollinger Bands', type='overlay')
class BollingerBands:
    period = param.number(default=20, min=2, max=500)
    std    = param.number(default=2.0, min=0.1, max=5.0, step=0.1)
    color  = param.color(default='#3b82f6')

    def plot(self, df):
        mid   = df['close'].rolling(self.period).mean()
        sigma = df['close'].rolling(self.period).std()
        upper = mid + self.std * sigma
        lower = mid - self.std * sigma
        return [
            Line(y=upper, color=self.color, line_dash='dashed'),
            Line(y=mid,   color=self.color),
            Line(y=lower, color=self.color, line_dash='dashed'),
            Fill(y1=upper, y2=lower, color=self.color, alpha=0.05),
        ]

CLI

Authentication

sixtysix login

Opens a browser window. After sign-in the refresh token is stored at ~/.sixtysix/config.json.

Local Docker backend

sixtysix start          # Pull latest image and start container
sixtysix stop           # Stop and remove container (data preserved)
sixtysix restart        # Restart container
sixtysix status         # Show container status and uptime
sixtysix logs           # Tail logs  (-n 100  --follow / -f)
sixtysix update         # Pull latest image and replace container

Backtesting

sixtysix backtest accounts                            # List your broker accounts and their aliases
sixtysix backtest strategies                          # List available strategies
sixtysix backtest params sma_crossover                # Show configurable params

sixtysix backtest run -s sma_crossover -S AAPL,TSLA -t 1h -a "My IBKR"
sixtysix backtest run -s sma_crossover -S SPY -t 1d -d 730 --capital 50000 -a "Alpaca Paper"
sixtysix backtest run -s ha_pullback -S AAPL -t 1h --params '{"atr_mult": 2.0}' -a 3

Flag	Default	Description
-s	required	Strategy name
-S	required	Comma-separated symbols
-a / --account	required	Account alias or numeric account ID (see backtest accounts)
-t	1h	Timeframe (1m 5m 15m 30m 1h 4h 1d 1w)
-d	365	Days of historical data
--capital	10000	Initial capital
--position-size	0.95	Fraction of equity per trade
--no-save	—	Don't persist results to database
--json	—	Output results as JSON

Results are saved to the database and visible in the UI at /backtest.

Cloud deployment (Hetzner)

sixtysix cloud deploy   # Interactive wizard: creates VPS, installs Docker, starts backend
sixtysix cloud status   # Show server IP, type, and running status
sixtysix cloud logs     # Stream logs from the remote container  (-f to follow)
sixtysix cloud restart  # Restart container on remote server
sixtysix cloud update   # Pull latest image on remote server
sixtysix cloud ssh      # Open SSH session
sixtysix cloud destroy  # Delete the server (irreversible)
