Technical analysis indicators for financial data.

This module provides common technical indicators used by traders and analysts. All indicators work with time series price data from OHLCV candles.

Available Indicators

Moving Averages

• sma - Simple Moving Average
• ema - Exponential Moving Average

Momentum Oscillators

• rsi - Relative Strength Index

Trend Indicators

• macd - Moving Average Convergence Divergence

Volatility Indicators

• bollinger_bands - Bollinger Bands
• atr - Average True Range

Example

use finance_query::{Ticker, Interval, TimeRange};

let ticker = Ticker::new("AAPL").await?;
let chart = ticker.chart(Interval::OneDay, TimeRange::ThreeMonths).await?;

// Use Chart extension methods (requires "indicators" feature)
let sma_20 = chart.sma(20);
let rsi_14 = chart.rsi(14)?;
let atr_14 = chart.atr(14)?;

// Or call indicators directly
let closes: Vec<f64> = chart.candles.iter().map(|c| c.close).collect();
let ema_12 = finance_query::indicators::ema(&closes, 12);
