Trend indicators
VIDYA: Variable Index Dynamic Average
An exponential average that speeds up when momentum is strong and slows down when it is weak.
Идея простыми словами
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.
Как считается
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|)Как использовать
- A trend line that stays calm in sideways markets and reacts in strong moves.
- Combine with a breakout: VIDYA turning steeply confirms momentum.
Выводы
- Flat VIDYA: momentum is balanced, trend signals are unreliable.
Пример
On a stock index H1 chart VIDYA stays flat through a quiet morning, then tilts sharply when the price breaks out after a news release.
Цены в примерах приведены для иллюстрации.
На что обратить внимание
