How to trade with Gator Oscillator


The Gator Oscillator histogram above zero shows the absolute difference between blue and red lines of Alligator indicator, while histogram below zero shows the absolute difference between red and green lines.

There are green and red bars on the Gator Oscillator histograms.
A green bar appears when its value is higher than the value of the previous bar.
A red bars appears when its value is lower than the value of the previous bar.

Gator Oscillator helps to better visualize the upcoming changes in the trends: to know when Alligator sleeps, eats, fills out and is about to go to sleep.

Now let's see what Gator does

Gator indicator Forex

Gator Awakes

- when after sleeping one of the indicator bars is red and the other one is green (either above or below zero)

Gator Eats

- when both bars (above and below zero) are green.

Gator fills out

- when after eating one of the bars turn red.

Gator Sleeps

- when both bars are red.

By default, Gator oscillator is set with a slight shift forward when displaying oscillator bars.
When working with Gator oscillator in real time, there is no impact/difference, but if to attempt visual backtesting, such shift would prohibit from making a real evaluation of Gator indicator performance. Therefore, it is recommended to set shift value to zero as shown on the screenshot below:

after 5 years trade, finally i found the best trading method for me. This method is realy the best. I tried on Bullion Gold and the result makes me happy all the time. Thanks to you bro!. I add up MA 50 shift 13 smoothed median and MA 365 shift 50 smoothed median also, so, I trade in all timeframes from M1 to Weekly chart. When I combine with Fibo which I add the level, -23.6, -38.2, -61.8, 161.8, -261.8, -423.6, I really buy or sell at the beginning of trend ..means my entry on M1 chart and close position/(s) at the end of the wave ( 5th waves). Thanks again. God Bless you...
