Question: What was Cintas's MACD Histogram on July 15, 2021? (Standard parameters: fast 12, slow 26, signal 9; Require 104 data points to warm up; EMA uses the first data point as the initial value) 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: MACD Histogram = MACD Line - Signal Line; MACD Line = EMA_{n_{fast}}(P) - EMA_{n_{slow}}(P); Signal Line = EMA_{n_{signal}}(MACD Line)
