Abbreviation: Volume Advancing-Volume Declining Spread: ExpAvg Diff
Category: Market Volume Advance / Decline
Input Parameters:
| Name | Range | Default |
| Volume of Advancing Issues | ||
| Volume of Declining Issues | ||
| ExpAvg1 Periods | Int >=1 | 5 |
| ExpAvg2 Periods | Int >=1 | 10 |
Calculation:
ExpAvg(X, ExpAvg1 Periods) – ExpAvg(X, ExpAvg2 Periods)
where
X = Volume Advancing-Volume Declining Spread(Volume of Adv Issues, Volume of Dec Issues)
Volume Advancing-Volume Declining Spread represents Volume Advancing-Volume Declining Spread
ExpAvg represents Exponential Moving Average
Discussion:
This indicator attempts to quantify movements in the Volume Advancing-Volume Declining Spread indicator by calculating the difference between two moving averages. Since it uses exponential moving averages (which give more importance to the most recent periods than to less recent periods), the indicator tends to focus more upon movement occurring in the most recent periods.
