This review is about the Turtle Trading System 2 EA. I have no affiliation
with anyone in conjunction with this review.
I got this EA as part of an ebook from Daniel Fernández Pinto who runs the blog site
http://fxreviews.blogspot.com/. The eBook was $18.95 with the title Automated Trading in the Forex Market: A Trader's Guide to Success. This ebook is worthy of a discussion itself (but that is another story).
Along with the ebook came three EA's (source included ) and one of them was the Turtle Trading System 2.
Anyone who has read a decent amount of trading history knows about the Turtle Traders. If you don't or need a re-fresher, try:
Original Turtle Trading System Rules Richard Dennis at Wikipedia (one of two men that started the whole thing off)
Turtle background information Turtle Trading at Investopedia
Turtle Trading is a long-term strategy that uses the highest high of n days and the lowest low of n days (this is called a
Donchian channel).
This strategy uses two of these Donchain channels. The original
strategy called for the slow channel at 55 bars and the fast channel at
20 bars.
I am using this stratey on a EURUSD daily chart so one bar is one day. I am using a modified version of the original strategy where the slow channel is 55 days and the fast channel is 10 days.
The strategy opens a trade when the slow channel is penetrated (long trade if the upper boundary is penetrated,
short 
trade if the lower boundary is penetrated). The trade is held until the fast channel boundary is penetrated (lower boundary in the case of a long, upper boundary in the case of a
short 
).
The lot size calculation and the
SL
point 
uses the ATR (
average true range).
Up to four orders can be open on one trade. The additional orders are opened as a result of pyramiding. Orders are added based on 1/2 ATR.
I have created a dedicated account on MyFXBook.com for this EA. This EA has to run alone as it is not coded to play nice with other EA's. The MyFXBook.com account is:

The EA has been added using 2% risk. See the backtest in the following
post (#2) for approximate performance based on the risk value.
The EA has a copyright of 2009, Metaquotes. I tried to hunt for the source
online to determine the license but could not find anything. I am going to
try and ask the ebook author about the license on this EA. I sent an email to
the author asking him about the EA copyright and the author responded by saying
that he holds the copright to this EA and the source code header containing
the copyright information is wrong. The author also asked me not to share
the EA as per his copyright.
Given the fact that the EA did not have a controllable magic number, only
create lot sizes with one decimal position (which for my
broker 
is wrong) and
uses the
MT4 global variables of the client terminal interface (which are different than
EA global variables) even though it uses the interface improperly and it is not
necessary, I have modified the EA so that:
-it now has a controllable magic number
-the lot size is now calculated to two decimal positions
-the
global variables of the client terminal are not reset every time the EA initializes

-strategy has been around forever and still works great
-proven long-term track record
