Abbreviation: Advance-Decline Spread: VolWgtAvg Diff
Category: Market Advance / Decline
Input Parameters:
Name | Range | Default |
Advancing Issues | ||
Declining Issues | ||
Total Volume | ||
VolWgtAvg1 Periods | Int >= 1 | 5 |
VolWgtAvg2 Periods | Int >= 1 | 10 |
Calculation:
VolWgtAvg(X, Total Volume, VolWgtAvg1 Periods) – VolWgtAvg(X, Total Volume, VolWgtAvg2 Periods)
where
X = Advance-Decline Spread(Advancing Issues, Declining Issues)
Advance-Decline Spread represents Advance-Decline Spread
VolWgtAvg represents Volume Weighted 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 volume weighted moving averages (which give more importance to those periods with higher volume relative to the other periods in the moving average’s time frame), the indicator tends to focus more upon movement between periods of relatively higher volume than between periods of relatively lower volume.
