## Formula

To calculate Williams Accumulation Distribution:

1. Calculate the True Range High and True Range Low:

True Range High is the greater of:

• High [today], and
• Closing price [yesterday]

True Range Low is the lesser of:

• Low [today]
• Closing price [yesterday]

2. Compare Closing price to yesterday's Closing price:

• If Close [today] is greater than Close [yesterday]
Price Move [today] = Close [today] - True Range Low
• If Close [today] is less than Close [yesterday]
Price Move [today] = Close [today] - True Range High
• If Close [today] equals Close [yesterday]
Price Move [today] = zero

3. Multiply the price move by volume:
AD [today] = Price Move [today] * Volume [today]

4. Calculate the cumulative total:
