Question: On September 02, 2022, what is the Average True Range value for Idexx Laboratories? (Standard period: 14; ATR calculation uses Wilder Smoothing, using the first data point as the initial value; Require 4n data points to warm up) Using unadjusted prices, write down the indicator formula, collect the raw data, calculate the answer, and keep four decimal places. Please list the raw data and key calculation process.
Formula: TR_t = max(H_t - L_t, |H_t - C_{t-1}|, |L_t - C_{t-1}|); ATR = Wilder_n(TR); Wilder Smoothing alpha = 1/n
