> [!TIP]
> *New in 0.28*:
>
> * Plotly 6 support
> * `ticker_kwargs` in `YFData`
> * Fixed Pandas TA dependency (→ [pandas-ta-classic](https://github.com/xgboosted/pandas-ta-classic)).

## :package: Installation

```sh
pip install -U vectorbt
```

To install optional dependencies as well:

```sh
pip install -U "vectorbt[full]"
```

## :sparkles: Usage

VectorBT lets you backtest strategies in just a few lines of Python.

* Profit from investing $100 in Bitcoin since 2014:

```python
import vectorbt as vbt

data = vbt.YFData.download("BTC-USD")
price = data.get("Close")

pf = vbt.Portfolio.from_holding(price, init_cash=100)
print(pf.total_profit())
```

```plaintext
19501.10906763755
```

* Buy when the 10-day SMA crosses above the 50-day SMA, and sell on the opposite crossover:

```python
fast_ma = vbt.MA.run(price, 10)
slow_ma = vbt.MA.run(price, 50)
entries = fast_ma.ma_crossed_above(slow_ma)
exits = fast_ma.ma_crossed_below(slow_ma)

pf = vbt.Portfolio.from_signals(price, entries, exits, init_cash=100)
print(pf.total_profit())
```

```plaintext
34417.80960086067
```

* Generate 1,000 strategies with random signals and test them on BTC and ETH:

```python
import numpy as np

symbols = ["BTC-USD", "ETH-USD"]
data = vbt.YFData.download(symbols, missing_index="drop")
price = data.get("Close")

n = np.random.randint(10, 101, size=1000).tolist()
pf = vbt.Portfolio.from_random_signals(price, n=n, init_cash=100, seed=42)

mean_expectancy = pf.trades.expectancy().groupby(["randnx_n", "symbol"]).mean()
fig = mean_expectancy.unstack().vbt.scatterplot(xaxis_title="randnx_n", yaxis_title="mean_expectancy")
fig.show()
```

* For hyperparameter optimization fans: test 10,000 window combinations of a dual-SMA crossover strategy on BTC, ETH, and XRP:

```python
symbols = ["BTC-USD", "ETH-USD", "XRP-USD"]
data = vbt.YFData.download(symbols, missing_index="drop")
price = data.get("Close")

windows = np.arange(2, 101)
fast_ma, slow_ma = vbt.MA.run_combs(price, window=windows, r=2, short_names=["fast", "slow"])
entries = fast_ma.ma_crossed_above(slow_ma)
exits = fast_ma.ma_crossed_below(slow_ma)

pf = vbt.Portfolio.from_signals(price, entries, exits, size=np.inf, fees=0.001, freq="1D")

fig = pf.total_return().vbt.heatmap(
    x_level="fast_window", y_level="slow_window", slider_level="symbol", symmetric=True,
    trace_kwargs=dict(colorbar=dict(title="Total return", tickformat="%")))
fig.show()
```

Inspect any strategy configuration by indexing with pandas:

```python
print(pf[(10, 20, "ETH-USD")].stats())
```

Same goes for plotting:

```python
pf[(10, 20, "ETH-USD")].plot().show()
```

It's not all about backtesting! VectorBT can also help with financial data analysis and visualization.

* Create a GIF that animates Bollinger Bands %B and bandwidth across multiple symbols:

```python
symbols = ["BTC-USD", "ETH-USD", "XRP-USD"]
data = vbt.YFData.download(symbols, period="6mo", missing_index="drop")
price = data.get("Close")
bbands = vbt.BBANDS.run(price)

def plot(index, bbands):
    bbands = bbands.loc[index]
    fig = vbt.make_subplots(
        rows=2, cols=1, shared_xaxes=True, vertical_spacing=0.15,
        subplot_titles=("%B", "Bandwidth"))
    fig.update_layout(showlegend=False, width=750, height=400)
    bbands.percent_b.vbt.ts_heatmap(
        trace_kwargs=dict(zmin=0, zmid=0.5, zmax=1, colorscale="Spectral", colorbar=dict(
            y=(fig.layout.yaxis.domain[0] + fig.layout.yaxis.domain[1]) / 2, len=0.5
        )), add_trace_kwargs=dict(row=1, col=1), fig=fig)
    bbands.bandwidth.vbt.ts_heatmap(
        trace_kwargs=dict(colorbar=dict(
            y=(fig.layout.yaxis2.domain[0] + fig.layout.yaxis2.domain[1]) / 2, len=0.5
        )), add_trace_kwargs=dict(row=2, col=1), fig=fig)
    return fig

vbt.save_animation("bbands.gif", bbands.wrapper.index, plot, bbands, delta=90, step=3, fps=3)
