Question: For Verisign's SuperTrend on August 29, 2025, what is the upper value? (Standard parameters: period 10, multiplier 3; Require 5n 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: Mid_t = (H_t + L_t) / 2; BasicUpper_t = Mid_t + m * ATR_n^{Wilder}; BasicLower_t = Mid_t - m * ATR_n^{Wilder}; in long state Lower_t = max(BasicLower_t, Lower_{t-1}), flip to short if C_t < Lower_t; in short state Upper_t = min(BasicUpper_t, Upper_{t-1}), flip to long if C_t > Upper_t
