To calculate your 10-day Accumulation Distribution, follow these steps. First, gather the daily volume, high, low, and closing prices for the time period in question. Next, calculate the Money Flow Multiplier ((closing price - low price) - (high price - closing price)) / (high price - low price). Multiply the Money Flow Multiplier by the corresponding day's volume to obtain the Money Flow Volume. Sum up the Money Flow Volume for the past 10 days to get the Accumulation Distribution. Remember to adjust the sum by adding the previous 10-day Accumulation Distribution value and subtracting the oldest day's Money Flow Volume. This will give you your 10-day Accumulation Distribution value.
