CYCLE INDICATOR
Detrended Price Oscillator
Removes a displaced moving average to highlight shorter cycles.
Start with the input, not the story.
Price deviation from a shifted trend estimate.
Plain-language formula
Price from a displaced point minus an N-period moving average.
Platform implementations can differ in price input, smoothing, indexing and rounding. Record the exact settings and provider before comparing results.
03 / USEFUL REGIME
Where it may help
Exploratory cycle-length research on stationary transformations.
04 / WEAK REGIME
Where it struggles
Real-time trading when implementations use centred or displaced values carelessly.
Add a different measurement.
Spectral or cycle researchATR
A complementary tool should answer a different question, such as volatility, regime or position risk. Test the base rule before testing the combination.
The shortcut to avoid
Using visually centred historical curves that leak future information.
A testable next step
Audit every index reference and evaluate only values available at the decision time.
