ManifoldBT compiles Python strategy definitions into an optimized Rust expression graph.
Write strategies in a fluent Python DSL — execute them on a vectorized Rust engine.
## Why ManifoldBT
- **Fast** — 500K bars in ~26ms. 161x faster than vectorbt, 1000x+ faster than backtrader.
- **Expressive** — fluent DSL with 30+ indicators, conditional logic, cross-asset references
- **Rigorous** — Monte Carlo, walk-forward, parameter sweeps, lookahead detection, exposure diagnostics
- **Portable** — `pip install`, no Rust toolchain needed. Works on Python 3.9+.
## Installation
```bash
pip install manifoldbt
```
With all extras (plotting, pandas, polars):
```bash
pip install manifoldbt[all]
```
## Quick Start
```python
import manifoldbt as mbt
from manifoldbt.indicators import close, ema
from manifoldbt.helpers import time_range, Interval, Slippage
fast = ema(close, 12)
slow = ema(close, 26)
strategy = (
mbt.Strategy.create("ema_crossover")
.signal("fast", fast)
.signal("slow", slow)
.signal("signal", mbt.when(fast > slow, mbt.lit(1.0), mbt.lit(-1.0)))
.size(mbt.col("signal") * mbt.lit(0.25))
)
start, end = time_range("2022-01-01", "2025-01-01")
config = mbt.BacktestConfig(
universe=[1],
time_range_start=start,
time_range_end=end,
bar_interval=Interval.hours(12),
initial_capital=10_000,
execution=mbt.ExecutionConfig(allow_short=True, max_position_pct=0.5),
fees=mbt.FeeConfig.binance_perps(),
slippage=Slippage.fixed_bps(2),
warmup_bars=30,
)
store = mbt.ingest(provider="binance", symbol="BTCUSDT", symbol_id=1,
start="2022-01-01T00:00:00Z", end="2025-01-01T00:00:00Z", interval="1h")
result = mbt.run(strategy, config, store)
print(result.summary())
```
## Loading data
Bring your own data, or pull it from a built-in connector — both return a
`DataStore` ready for `mbt.run(...)`.
**CSV** — free on all tiers, auto-detects standard / MetaTrader 4 / MetaTrader 5:
```python
store = mbt.import_csv("EURUSD_1m.csv", symbol="EURUSD", symbol_id=1,
interval="1m", asset_class="forex")
```
**Exchange connectors** — Binance, Bybit, Hyperliquid, dYdX, Bitstamp (free); Databento, Massive (Pro):
```python
store = mbt.ingest(provider="binance", symbol="BTCUSDT", symbol_id=1,
start="2024-01-01T00:00:00Z", end="2025-01-01T00:00:00Z")
```
Or from the CLI:
```bash
manifoldbt import-csv data.csv --symbol EURUSD --symbol-id 1 --interval 1m
manifoldbt ingest --provider binance --symbol BTCUSDT --symbol-id 1 --start ... --end ...
```
