Alligator Analysis 外汇EA

Indicator description.

           The “Alligator Analysis” (AA) indicator allows you to build various (by averaging
types and by scales) “Alligators” and their combinations, i.e. allows you to analyze
the state of the market based on the correlation of this state with a whole
range of different “Alligators“.  The classic “Alligator” by Bill Williams is based on moving averages and Fibonacci
numbers, which makes it one of the best indicators now. The classic “Alligator”  is based on Fibonacci numbers and is a
combination of three smoothed moving averages (SМMA) with periods 5, 8 and 13,
which are part of the Fibonacci sequence. In this case, the moving averages are
shifted forwards by 3, 5, and 8 bars, respectively, which are numbers from the
same sequence (preceding the corresponding period values).

          
Alligators from the AA indicator is
based, on the same principle as the classic “Alligator”, but on
different parts of a number of Fibonacci numbers, as well as on different
moving average averaging algorithms.

          First
of all, in the AA  indicator you can create
8 types of alligators and their combinations:

1. Fast alligator with
   periods (3,5,8)  and shifts (2,3,5);

2. Classic
   alligator –  (5,8,13)
   and  (3,5,8); 

3.  Big
   alligator  –  (8,13,21) 
   and  (5,8,13);

4.  Huge
   alligator –  (13,21,34)
   and   (8,13,21);

5.  Monster –  (21,34,55) 
   and (13,21,34);

6.  Fast and
   Huge –  (3,5,8,13,21,34) and  (2, 3, 5, 8, 13, 21);

7.  Classic and
   Monster  –  (5,8,13,21,34,55) 
   and  (3,5,8,13,21,34);

8.  All
   alligators – 
   (3,5,8,13,21,34,55)  and  (2, 3,5,8,13,21,34).  

           Secondly, the indicator AA uses 6 types of averaging, where the classical averaging SMA,
   EMA, SMMA, LMA are supplemented by averaging the moving average by the median
   and averaging weighted by volume.

             
   Line shifts can be removed. The colors of the AA
   indicator lines are set according to the type of color spectrum: from violet
   for a small smoothing period to red – for the largest period.

    

   Application of “Alligator Analysis” in
   trade.

           In the “Fast alligator”, “Classic
alligator”, “Big alligator”, “Huge alligator” and “Monster”
modes, you can evaluate market trends in their respective (incremental) time
scales. In “All alligators” modes and near  to it – “Fast and Huge” and “Classic and Monster” –
the indicator “Alligator Analysis” allows you to see market
tendency of different (but important for trading on this chart) time scales on
the same chart. As a result,
it is easy to visually identify not only the states of (A) price consolidation
near a level (convergence and interlacing of lines, which become horizontal),
(B) the beginning of trends (“opening the mouth of a
crocodile”) and (C) their ends (interlacing of lines, indicating a
new consolidation), as in the classic Alligator, but also (D) rollbacks
of trends.

          Namely, if the “mouth of the crocodile”
is widely open on moving averages with large periods, which have a trend
identified on their timeframes, while a consolidation starts on the moving
averages of smaller scales, then a trend rollback is likely to take
place. At the same time, the length of a trend on the corresponding timeframe
is usually proportional to the length of the preceding consolidation area (of
the same scale), where the market remains most of the time (70%-80%), which
provides additional information for evaluating the market situation, i.e.
allows seeing if a trend rollback is beginning or ending.  A rough estimate is that if the trend lasted
for 25% -40% of the time of the consolidation before it, then, most likely,
there will not be a trend rollback, but a trend end;  if the trend lasted less than 20% of the time of the previous consolidation,
the convergence of the fast lines of the indicator «Alligator
Analysis»  indicates a rollback.
