How Gator Oscillator is calculated

Upper[d] = |Jaw raw[d−8] − Teeth raw[d−5]|
Lower[d] = −|Teeth raw[d−5] − Lips raw[d−3]|
Gator histogram display shift = min(8, 5) = +5

Version 1.0.0 calls the same governed median-price SMMA engine as the Alligator route. Values are compared at one display column so each fixed Alligator shift is respected.

The upper histogram is non-negative. The lower absolute gap carries a minus sign so it is drawn below zero. The standard Gator implementation displays both through a common +5 shift.

Assumptions and limits

  • At least 18 ordered high-low bars are required for one fully aligned value.
  • Rows must be oldest to newest and use one symbol, timeframe and feed.
  • The standard 13/8/5 periods and 8/5/3 line shifts are fixed.
  • Available history and the chosen starting row can change seeded SMMA values.
  • Histogram colors, growing or fading states, phase names, direction and trades are withheld.

Worked example from the audited fixture

Reproduce it with “Load audited example”The audited 24-bar Alligator fixture produces seven aligned Gator points. At the latest display index 26, the Jaw-to-Teeth absolute gap is 4.820909 and the Teeth-to-Lips gap is shown below zero as −4.484989.

How to interpret the result

The lower value is negative only because the published display convention places that absolute gap below zero. Neither sign describes return direction. Both gaps compare shift-aligned Alligator values at one display column and do not create a market-state label.

Frequently asked questions

  • Enter at least 18 ordered high-low bars from one symbol, timeframe and broker feed.
  • It is the absolute difference between display-aligned Jaw and Teeth values.
  • It is the negative absolute difference between display-aligned Teeth and Lips values.
  • The shared engine uses median-price SMMAs with standard periods 13, 8 and 5 and shifts 8, 5 and 3.
  • The standard implementation displays both histograms with the smaller Jaw and Teeth shift, which is five bars.
  • Available feed history and the entered seed starting point can change the underlying smoothed averages.
  • No. The page reports line-distance arithmetic without strength, direction or trend classification.
  • No. Color, growing or fading states, phase names, entries and exits are withheld.
