Rsi

class backtide.strategies.Rsi(rsi_period=14, bb_period=20, bb_std=2.0)

Relative Strength Index combined with Bollinger Bands for dual confirmation.

Combines RSI and Bollinger Bands. Enters long when RSI is in oversold territory and price is at or below the lower Bollinger Band, giving a dual confirmation of mean-reversion conditions. Exits when RSI returns to neutral or price reaches the upper band. Useful for catching bounces with higher conviction than RSI or Bollinger Bands alone.

Parameters	rsi_period : int, default=14 RSI look-back period. bb_period : int, default=20 Bollinger Band moving average period. bb_std : float, default=2.0 Number of standard deviations for the bands.
Attributes	name : str Human-readable strategy name. is_multi_asset : bool Whether this is a multi-asset strategy.

Methods

description	Short explanation of what the strategy does.
evaluate	Evaluate the strategy and return orders.
required_indicators	Indicators that must be computed up-front for this strategy.

method description()

Short explanation of what the strategy does.

Returns

str

The description.

method evaluate(data, portfolio, state, indicators=None)

Evaluate the strategy and return orders.

Parameters

data : dict[str, numpy.ndarray | pandas.DataFrame | polars.DataFrame]

Keys are the experiment's symbols and values are the historical OHLCV data available up to the current bar. For example, data["AAPL"]["close"] selects AAPL's visible close-price history.

portfolio : backtide.backtest.Portfolio

Current portfolio holdings (cash, positions and open orders). For example, portfolio.positions.get("AAPL", 0.0) returns the current signed quantity, while portfolio.orders contains pending orders.

state : backtide.backtest.State

Current simulation state. For example, use state.is_warmup to suppress orders during warmup and state.datetime to read the current bar's timezone-aware timestamp.

indicators : dict[str, dict[str, numpy.ndarray | pandas.DataFrame | polars.DataFrame]] | None

The first keys are the indicator names. The second keys are the experiment's symbols. The values are the pre-computed indicator histories available up to the current bar. For example, indicators["SMA_20"]["AAPL"] selects AAPL's visible 20-bar SMA history. None is permitted when no indicators were selected.

Returns

list[Order]

Orders to place this tick.

method required_indicators()

Indicators that must be computed up-front for this strategy.

Returns a list of indicator instances, already parameterized with this strategy's current settings, that the engine will auto-include before the backtest starts.

Returns

list[BaseIndicator]

The required indicator instances.
