pub fn true_range(
    highs: &[f64],
    lows: &[f64],
    closes: &[f64],
) -> Result<Vec<Option<f64>>>

TR = max(high - low, |high - prev_close|, |low - prev_close|)

Arguments

• lows - Low prices
• closes - Close prices

Example

use finance_query::indicators::true_range;

let closes = vec![9.0, 10.0, 11.0];
let result = true_range(&highs, &lows, &closes).unwrap();
