Hello Baby, [:D]

I shall get back to you tonight, in about 5 hours, but until then, be warned:

Someone on this forum is about to tell you to study Metastock's Formula Primer. [6][:@] Don't bother with him! [:D]

RTFM: You cannot use the Input() function anywhere except in indicators; you have to hard code the values you want for each variable. wabbit [:D]

Hi Pet, [:)]

In Expert Editor go to Trends,. In Bullish field, paste this code:

loss:=3.5*ATR(5);
trail:=
If(C>PREV AND Ref(C,-1)>PREV,
Max(PREV,C-loss),
If(C<PREV AND Ref(C,-1)<PREV,
Min(PREV,C+loss),
If(C>PREV,C-loss,C+loss)));
trail;
C>trail

In Bearish field, paste this code:

loss:=3.5*ATR(5);
trail:=
If(C>PREV AND Ref(C,-1)>PREV,
Max(PREV,C-loss),
If(C<PREV AND Ref(C,-1)<PREV,
Min(PREV,C+loss),
If(C>PREV,C-loss,C+loss)));
trail;
C<trail

As you see above, ATRPER has been replaced with 5, and ATRFACT has been replaced with 3.5.
You can change these values.

(Picture is available only for the next 6 months from today).

For EST, Buy Order:

loss:=3.5*ATR(5);
trail:=
If(C>PREV AND Ref(C,-1)>PREV,
Max(PREV,C-loss),
If(C<PREV AND Ref(C,-1)<PREV,
Min(PREV,C+loss),
If(C>PREV,C-loss,C+loss)));
trail;
cross(c,trail)

and for Sell short Order:

loss:=3.5*ATR(5);
trail:=
If(C>PREV AND Ref(C,-1)>PREV,
Max(PREV,C-loss),
If(C<PREV AND Ref(C,-1)<PREV,
Min(PREV,C+loss),
If(C>PREV,C-loss,C+loss)));
trail;
cross(trail,c)

Judging from your questions, I don't think you will be able to interpret the results from testing properly, but if you play with testing the existing systems that come with Metastock long enough, you will get some idea. (Those systems come with ready made Indicators, Explorations and Expert Advisors).

The ATR Trailing Stop is eye-pleasing and I wonder if you are going to turn a profit from using it. Many things that look catchy and test catchy do not translate into $$$ to traders.

Bon chance! [:)]

PS: see TASC MAY 2010 magazine
Sylvain Vervoort’s article Smoothing The Bollinger %b.
http://stocata.org/metastock/bollinger_perc_b.html
Sylvain has a suite of Indicators like the one you asked about,
not only the Bollinger %b.

Hi Pet, [:)]

Here are Sylvain's Metastock formulas:

http://stocata.org/metastock/formulas.html

He is in high demand, published original articles and book http://stocata.org/aboutus.html and already lectured outside Holland where he resides.

Rather than chasing a wild goose, follow this master for 1-2 years until your wings grow enough for you to fly alone. [:D]
