VIDYA: Variable Index Dynamic Average
An exponential average that speeds up when momentum is strong and slows down when it is weak.
הרעיון במילים פשוטות
It watches the balance between up moves and down moves (the Chande Momentum Oscillator). Strong one-sided momentum makes the average follow faster; balanced, indecisive trading makes it slow.
איך זה מחושב
CMO compares the sum of recent up-moves with the sum of down-moves. Its absolute value (0 to 1) scales the speed of an EMA.
CMO = (sum of ups − sum of downs) ÷ (sum of ups + sum of downs) over 9 candles
k = 2 ÷ (12 + 1)
VIDYA today = close × k × |CMO| + VIDYA yesterday × (1 − k × |CMO|)איך משתמשים בזה
- A trend line that stays calm in sideways markets and reacts in strong moves.
- Combine with a breakout: VIDYA turning steeply confirms momentum.
הסקת מסקנות
- Flat VIDYA: momentum is balanced, trend signals are unreliable.
דוגמה
