Is the Bill Williams "Alligator" formula available for Telechart?

If so, please provide.  

If you need more info., please ask.

Welcome to the forums. A very good foundation for learning how to use TeleChart can be gained by reviewing the following:

If you are new to TeleChart READ THIS FIRST!

Please try the following to recreate the Alligator indicator in TeleChart:

Lips:
Select Chart Template | Add Indicator | Indicator | Top.
- Draw Color: Green
- Draw Style: Normal or Wide
- Center Zero Line: Unchecked
- Plot using price scale: Checked
- Smoothing Average: 9
- Average Type: Exponential
- Indicator Formula: (H3 + L3) / 2

Teeth:
Select Chart Template | Add Indicator | Indicator | Top.
- Draw Color: Red
- Draw Style: Normal or Wide
- Center Zero Line: Unchecked
- Plot using price scale: Checked
- Smoothing Average: 15
- Average Type: Exponential
- Indicator Formula: (H5 + L5) / 2

Jaw:
Select Chart Template | Add Indicator | Indicator | Top.
- Draw Color: Blue
- Draw Style: Normal or Wide
- Center Zero Line: Unchecked
- Plot using price scale: Checked
- Smoothing Average: 25
- Average Type: Exponential
- Indicator Formula: (H8 + L8) / 2

Awesome Oscillator (AO):
Select Chart Template | Add Indicator | Indicator.
- Draw Color: Up to you.
- Draw Style: Up to you.
- Visible: Checked
- Center Zero Line: Checked
- Plot using price scale: Unchecked
- Smoothing Average: 1
- Average Type: Doesn't matter (because the Smoothing Average is 1).
- Indicator Formula: (AVGH5 + AVGL5 - AVGH34 - AVGL34) / 2

Acceleration/Deceleration (AC):
Select Chart Template | Add Indicator | Indicator.
- Draw Color: Up to you.
- Draw Style: Up to you.
- Visible: Checked
- Center Zero Line: Checked
- Plot using price scale: Unchecked
- Smoothing Average: 1
- Average Type: Doesn't matter (because the Smoothing Average is 1).
- Indicator Formula: (AVGH5 + AVGL5 - AVGH34 - AVGL34 - AVG(AVGH5,5) - AVG(AVGL5,5) + AVG(AVGH34,5) + AVG(AVGL34,5)) / 2

That said, all Histograms will be plotted as line charts instead of bar charts and be a single color instead of multiple colors and the Alligator will end at the current date instead of extending beyond the right edge of the Chart. You may wish to review the following:

Several months ago, Bruce L furnished me with formulas that simulated Bill Williams' " Alligator" charts.  Are those same formulas usable in Stockfinder.  If so, how do I code them in Stockfinder?  If not, please code them in the Stockfinder code.

Is it possible to write the product of searches/filters in a Watchlist having a watchlist "dataname" usable in both by both Telechart and/or Stockfinder?

TeleChart's Personal Criteria Formula Language is not implemented in StockFinder (which uses RealCode instead). My Monday, November 09, 2009 1:39:04 PM ET post in finding old posts has an attached Chart which will hopefully do what you want.

I do not know what "Is it possible to write the product of searches/filters in a Watchlist having a watchlist "dataname" usable in both by both Telechart and/or Stockfinder?" means. That said, it is possible to view TeleChart's WatchLists in StockFinder (select TeleChart - Active List, TeleChart - Sorted Active List or choose one of the Personal WatchLists listed under the TeleChart section of the WatchList drop-down menu in StockFinder), but it is not possible to view StockFinder's WatchLists in TeleChart.

Bruce

looking at this vs. the now built in Alligator,

it appears the smoothing average should be

 

LIPS 5 Simple

TEETH 8 Simple

JAWS 13 Simple

 

 

 

 

 

 

Thanks

Yes. The Williams Alligator indicator in TC2000 version 12.1 is using Simple Moving Averages for its calculations.

Above you recommend

 

 

LIPS        9 Exponential

TEETH   15 Exponential

JAWS     25 Exponential

My recommendations are based on a Simplified Moving Average (which is Wilder's Smoothing). TC2000 version 12.1 is using a Simple Moving Average instead.

Why did you choose that interpretation vs the standard?

This topic significantly predates the release of TC2000 version 12.1. I chose to use Simplified Moving Average because it is what is used by Bill Williams.

Ok, but it is somewhat confusing.

In this post several years before this one you recommend what matches today’s telechart.

Simple, 5,8,13.

http://forums.worden.com/default.aspx?g=posts&t=14797

 

In his book Trading Chaos

Williams recommends

5,8,13, smoothed averages.

 

 

I was trying to create a PCF for

5 above 8 and 8 above 13

and one for

5 below 8, and 8 below 13

 

Obviously, the first question is what is it?

(Im not a Williams expert)

the 9,15,25, threw me.

 

Im guessing you play no role in the selection of parameters in Telecharts canned indicators,

unless it’s the new ones from Technical Analysis of Stocks and Commodities magazine?

 

 

 

Thanks

You may want to re-read the topic you linked to again as it specifically recommends the Simplified/Smoothed/Wilder's Moving Average and not a Simple Moving Average.

The 9, 15 and 25 are the Exponential Moving Average periods which result after converting the 5, 8 and 13 period Simplied/Smoothed/Wilder's Moving Average periods by multiplying them by two and then subtracting one from the result.

And no, I do not have a role in choosing the parameters used when indicators are implemented in our products.
