Acceleration Deceleration Oscillator (ACCDEOSC)

StratCraft indicator page for the Acceleration/Deceleration Oscillator.

Route: /indicators/accdeosc/

What It Does

ACCDEOSC measures the change in the momentum of price acceleration. It is used to detect when the speed of a trend is increasing or fading.

Formula

Median Price = (High + Low) / 2

AO = SMA(Median Price, 5) - SMA(Median Price, 34)

ACCDEOSC = AO - SMA(AO, 5) (default period = 5; the movav parameter selects the final average).

Worked Example

For five illustrative AO values 1, 2, 2, 1, 2, SMA(AO, 5) = 1.6. On the fifth bar, ACCDEOSC = 2 - 1.6 = 0.4. These AO values are supplied for arithmetic only; a full AO needs at least 34 median-price bars.

Parameters

  • period - default 5
  • movav - default SMA

Backtrader API

import backtrader as bt
accdeosc = bt.indicators.AccDeOsc(data, period=5)

Common Usage

  • Use ACCDEOSC as a momentum change detector.
  • Combine it with trend filters to avoid noise.
  • Watch for sign changes or threshold breaks.

Practical Pattern

Acceleration fading after a strong move can warn that the current trend is losing strength.
