use-quant

Facade crate for RustUse quantitative finance primitives.

use-quant is a thin re-export layer over focused child crates for market prices, returns, bars, ticks, price series, volatility, drawdowns, portfolio weights, factors, signal scores, and risk vocabulary. Most implementation lives in the focused crates.

This crate is not a trading system, backtesting framework, financial advisor, broker integration, market data provider, charting library, strategy engine, portfolio optimizer, risk platform, finance system, or accounting system.

Example

use use_quant::{market_price, price_series, return_};

let start = market_price::MarketPrice::new(100.0)?;
let end = market_price::MarketPrice::new(105.0)?;
let simple = return_::SimpleReturn::from_prices(start.value(), end.value())?;

let mut series = price_series::PriceSeries::new();
series.push(price_series::PricePoint::new(start));
series.push(price_series::PricePoint::new(end));

assert!((simple.value() - 0.05).abs() < 1.0e-12);
assert_eq!(series.len(), 2);
# Ok::<(), Box<dyn std::error::Error>>(())

Modules

• market_price re-exports use-market-price
• return_ re-exports use-return
• bar re-exports use-bar
• tick re-exports use-tick
• price_series re-exports use-price-series
• volatility re-exports use-volatility
• drawdown re-exports use-drawdown
• portfolio_weight re-exports use-portfolio-weight
• factor re-exports use-factor
• signal_score re-exports use-signal-score
• risk re-exports use-risk

Scope

Use the facade when one dependency and one import surface are useful. Use focused crates directly when a library only needs one primitive area. Business and accounting concepts belong in a possible future use-finance set.
