Question: For Qualcomm's Keltner Channel on May 18, 2023, what is the middle value? (Standard parameters: middle EMA(20), requiring 4n data points to warm up, using the first data point as the initial value; ATR(10) using Wilder smoothing, multiplier 1.5) 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: Middle = EMA_{n_{ema}}(C); Upper = Middle + 1.5 * ATR_{n_{atr}}^{Wilder}; Lower = Middle - 1.5 * ATR_{n_{atr}}^{Wilder}
