ಸರಳ ಅರ್ಥ
Momentum oscillators use different inputs and scales to describe location or deviation. Stochastic locates close within a high-low range, Williams %R expresses a related position on −100 to 0, CCI scales deviation from typical-price mean, and MFI adds reported volume.
Learning objectives #
You should be able to identify each oscillator's input, scale and denominator, explain why similar threshold labels do not make them interchangeable, and recognise when missing volume affects only volume-dependent studies.
Core concept #
Stochastic forms raw %K from close within the N-bar range and smooths %K and %D. Stochastic RSI applies the range calculation to Wilder RSI. Williams %R locates close from −100 at the low to 0 at the high. CCI divides typical-price deviation by 0.015 times mean absolute deviation. MFI converts signed raw money flow into a 0–100 ratio.
Method and conventions #
Choose an oscillator whose transformation matches the research question and record every period and smoothing stage. Do not stack several bounded oscillators and count agreement as independent evidence; many share the same price history.
Use it in XMarketRadar #
Add one oscillator, read its scale and warm-up, then compare its current value with its own history. In Screener, keep rows with invalid high-low range, deviation or volume unavailable rather than assigning midpoint values.
Worked example #
If a 14-bar high is 110, low 90 and close 105, unsmoothed stochastic %K is (105−90)/(110−90)×100=75, while Williams %R is (105−110)/20×100=−25. They encode the same range location on different orientations.
How to interpret it #
A higher stochastic value means close is nearer the selected range high. CCI can exceed conventional bands because it is not bounded. MFI reflects both price and volume flow classification but does not identify actual institutional inflow.
Limitations and common mistakes #
Common errors are mixing raw and smoothed %K, calling −20 Williams %R the same number as RSI 80, treating CCI as bounded, using MFI with missing volume and selecting thresholds after observing the outcome.
Market-specific differences #
Volume coverage varies across venues, so MFI availability can differ while price-only oscillators remain valid. Threshold frequency also changes with interval, volatility and price limits.
Key takeaway #
Key takeaway: oscillator names can sound similar while formulas, scales, inputs and failure states differ materially.
Practice exercise #
Practice: calculate stochastic and Williams %R from the same range, state their scale relationship, and identify which of four oscillators fails when volume is unavailable.
