Alligator Indicator: A Ribbon, Shifted
The alligator indicator is three smoothed moving averages of the bar midpoint - a 13-bar jaw, an 8-bar teeth and a 5-bar lips - each shifted several bars forward. Intertwined lines mean no trend, and the designer's instruction was to stand aside. Separation means a trend is already running.

Three smoothed averages, drawn at different lengths and pushed a few bars to the right of the last close. The animal is a naming convention; the arithmetic is a moving average ribbon with one extra step.
How it works
Three lines, three lengths, and a push to the right. Each is a smoothed moving average of the bar midpoint rather than the close, drawn a fixed number of bars ahead of the data that made it.
The settings are fixed. A 13-bar smoothed average shifted 8 bars forward is the jaw, an 8-bar shifted 5 forward is the teeth, and a 5-bar shifted 3 forward is the lips. That is the whole calculation.
The names do no work. Jaw, teeth and lips are three smoothed averages of different lengths, and calling them after an animal adds nothing to the calculation. It is a mnemonic, nothing more.
Intertwined lines are the sleeping state. When the three cross and re-cross inside a narrow band, the tool is reporting no trend to trade, and the instruction attached is to stand aside.
Separated and ordered lines are the waking state. Lips above teeth above jaw, fanning apart, says a trend is running — the same reading anyone makes by eye off a moving average stack.
Late twice over
The forward shift is the one structural difference from an ordinary ribbon. Each line is drawn several bars to the right of the data that produced it, so the lines appear to run ahead of price.
That appearance is cosmetic. A value plotted at a future position was computed from bars already closed, and an average first smoothed and then displaced is late twice over.
It reads price only. Like every moving average it takes highs and lows and nothing else, so volume plays no part in whether the lines separate or tangle.
On a daily chart the jaw carries a long memory. Thirteen daily bars is most of three trading weeks, smoothed and then pushed forward again, which is why the state changes slowly, and late.
In practice
One large bar can separate the lines with nothing behind it. An overnight gap moves all three averages at once, and what follows looks like a trend beginning rather than one bar arriving.
The slowest line is the usual trailing reference. Traders using it put a stop beyond the jaw and move it as the jaw moves, which is a trailing rule with an ordinary average doing the work.
Every signal costs a round trip. Each entry and exit pays the spread and any commission, so a tool that wakes and sleeps often pays that toll repeatedly, and a small move caught between two crossings can be smaller than the toll.
Read plainly, it is a ribbon with a memorable name. A short pair of smoothed averages crosses far more often than a long pair, so the lengths chosen here set how often the tool says anything at all.
An indicator that mostly says no
A tool whose main output is “do not trade” is unusual. Most indicators exist to produce signals, because a signal feels like value, and this one spends most of its life reporting that conditions are not there.
Real prices back that reading. The S&P 500 climbed from 1950 to 2026, yet only 59% of its ten-day windows finished higher and the other 41% finished flat or lower, so even a decades-long advance spent much of its time looking tangled on a short view.
So a clean, separated fan is the exception rather than the rule. An indicator asleep most of the time is not failing to find something. It is agreeing with what price actually does.
That is the honest case for it, and it is a low bar. Any ribbon reads the same way, and trend analysis needs no animal attached to be done properly.
What the alligator indicator is not
- It is not a leading indicator. The shift moves the drawing, not the information.
- It is not a trading system. Three averages decide nothing about size or exit.
- It is unrelated to Williams fractals arithmetically. Shared author, separate calculation.
- It is not a measure of strength. Wide separation says the averages differ.
How this connects
Three smoothed moving averages, displaced forward. That is the whole construction, which puts it in the same family as a moving average ribbon.
The displacement is what makes it unusual. Shifting a line forward draws it beside bars it was not computed from, which looks like anticipation and is not.
The lines separating is read as a trend. Intertwined lines mean the averages agree, which happens in a trading range; separation means recent price has pulled the fast line away.
It is usually paired with Williams fractals, which mark swing points - the fractal supplies the level and the alligator supplies the context.
And all three lines come from the same closes, so their agreement is arithmetic rather than three independent readings confirming each other.
When it fails
In a range the lines tangle and stay tangled. That is the tool working correctly, and it is also most of the chart.
The wake-up arrives after the move has started. Smoothing plus displacement means separation is confirmed by bars that have already printed, and the first leg is usually gone.
A gap or one outsized bar fakes the separation. The lines pull apart because the input jumped, not because a trend arrived, and the next bars often close the fan again.
Whipsaw is the standing cost in choppy conditions. Shorter averages cross more often than longer ones, and every crossing that reverses is paid for twice.
Tuning the lengths until the chart agrees is not analysis. Changing them after the fact only makes the past look tidier than it was.
One timeframe hides the disagreement. The same instrument can be asleep on the hourly chart and awake on the daily, and nothing says which reading wins.
The original data
One video in the corpus carries “alligator indicator” in its title. Measured across 24,971 trading and investing videos and stored in the site’s video study, that single video has 16,922 views and comes from 1 channel.
Set that beside the crowded names. The same corpus holds 268 Bollinger Bands videos with a median of 4,842 views across 204 channels, and 151 ichimoku videos with a median of 10,245 views across 99 channels.
Scarcity here is not opportunity, and it is not evidence of neglect. One video from one channel is far too small a sample to read demand from. It says only that almost nobody teaches this by name.
The useful move is comparison, not adoption. Put the jaw, teeth and lips on a chart beside a plain three-length ribbon, cover the right-hand side at the bar where the lines first separate, and write down which one you would have acted on before checking what happened next.
Related
The ribbon is the same idea without the forward shift, so moving average ribbon is where to see what a stack of averages says on its own.
Williams fractals came from the same author and are usually shown alongside it, which is a fact about authorship rather than about arithmetic.
And trend analysis is the job all of this is trying to do, set out in plain reading before any indicator is added to the chart.
The useful part of this indicator is not the entries. It is the permission to sit out: when the lines are tangled you are looking at chop, and forcing trades in that condition tends to cost more than catching the start of a move earns. Read it as a ribbon and ignore the animal.
