Gator Oscillator

What is the Gator Oscillator?

The Gator oscillator is a forex trading tool developed by Bill Williams. It is closely related to the similar Alligator oscillator. As a trend indicator itd is most useful in markets that display strong directional action. 

Note: Past performance is not indicative of future results.

On this chart, the upper section shows the price action, while the lower part is the Gator indicator. The smoothed moving averages that create the value of the bars are not depicted on the graph. As you can see, each bar of the indicator is comprised of a lower and an upper section the interaction of which determines the way the indicator is interpreted.

Calculation

The indicator is calculated according to the following formulae.

Median Price = (High + Low)/2

Jaw (lower moving average) = Smoothed moving average of the median price over 13-period

Teeth (upper moving average) = Smoothed moving average of median over 8-period

Lips (middle moving average) = Smoothed moving Average of the median over 5-period

These values, called balance lines, are calculated and shifted into the future by an amount specified by the trader. If the moving averages themselves are depicted on the charts, the jaw will be blue, the teeth will be in red, and the lips will be green most of the time. In our graph, the smoothed moving averages (i.e. balance lines) are not shown.

The bars seen below the centerline in the chart above show the absolute difference between the red line and the green line with a minus sign. The upper bars, on the other hand, depict the difference between the blue and the red lines.More concisely.

Top bar = Jaw - Teeth

Bottom bar = - (Absolute value of (Teeth - Lips))

The indicators is then evaluated on the basis of the emerging green or red patterns.

Usage

In order to interpret this indicator, we must define three states of the indicator bars.

Gator Awaking

Signifying the completion of a cycle, when the bars display different colors (any combination of red and green), the gator is 'awaking'.

Gator Eating

When both the bar below and the one above the centerline are green, the indicator is said to be eating.

Gator Satisfied

When, after an 'eating' phase, the one of the upper or lower bars around the centerline turn red, the Gator is said to be sated.

Gator Sleeping

When both bars above and below the centerline are red, the gator is sleeping.

The indicator is then interpreted on the basis of a hypothesis that each phase of the trend has a life cycle of its own, indicated by the awaking-eating-stopping-sleeping of the gator. When a phase of the trend is at its incipient stages, we will observe that the gator is waking, that is, one of the upper or lower bars will turn green. After that, as the trend accelerates and reaches its climax, we will note an increasing number of 'double greens' where both the upper and the lower bars are green. This is the eating phase. As the phase runs out of energy, and begins to slow down, one of the previously green bars will turn red, signalling that the gator is sated. And when both bars are red, the phase has ended, anticipating a new cycle.

Trading with this indicator is simple and easy. In general you open a position as the bars contract and show different colors; then maintain the position until both bars turn red, and exit to take profit. And alternative, more conservative way of using the oscillator is placing the take-profit order at the satisfaction phase. In this manner, while there is chance that some of the potential of the trade will be left unrealized, we are able to capitalize on the most violent phase of the mini trend with shorter time exposure to the market.

Conclusions

The main problem with this oscillator is its complicated nature. It is essentially a combination of three moving averages, and whether the addition of the graph at the bottom contributes much value, or merely complicates the picture will probably depend on your trading style. If you depend on moving averages in trading trends, the gator is a suitable tool for balancing and condensing your strategy. All the problems of trading with a moving average must be taken into account while a trader is making use of the Gator indicator. If you make use of other tools, such as the MACD, and do not favor simple moving averages, theGator may not provide a lot of additional value.

The main advantage of the Gator indicator is the compactness of its display. Instead of drawing three separate SMMAs on the chart, we have all the information provided by them packed into the bars below, which leaves enough space for the application of any number of additional indicators onto the price data.

We will conclude by repeating that the oscillator is suitable to trending markets. It is most harmonious with Fibonacci levels, or support/resistance lines due to its tendency to be volatile and unpredictable.

Developed by Donald Lambert and first made public in 1980, the commodity channel index is a well-known tool used by some commodity and forex traders for identifying secular moves, and trading them.

The CCI has a crossover line at zero, and an overbought level at 100, while values below -100 are regarded as signaling an oversold condition. The CCI is an oscillator.

Note: Past performance is not indicative of future results.

Here we see the indicator in action in the price chart above. It is interesting to note that the CCI gives many false signals even at extreme values. For example, the lowest value for our indicator, at -283.576 was recorded during a very minor, and passing bottom on the chart. As with most high sensitivity indicators using the ATR requires a lot of practice and patience in mastering it.
