Abbreviation: Advance-Decline Spread: ExpAvg Diff
Category: Market Advance / Decline
Input Parameters:
| Name | Range | Default |
| Advancing Issues | ||
| Declining Issues | ||
| ExpAvg1 Periods | Int >= 1 | 5 |
| ExpAvg2 Periods | Int >= 1 | 10 |
Calculation:
ExpAvg(X, ExpAvg1 Periods) – ExpAvg(X, ExpAvg2 Periods)
where
X = Advance-Decline Spread(Advancing Issues, Declining Issues)
Advance-Decline Spread represents Advance-Decline Spread
ExpAvg represents Exponential Moving Average
Discussion:
This indicator attempts to quantify movements in the Advance-Decline 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.
