A futher thank you
for the assistance last week of Peter Kuskopf, Steve Roweau, and Roy Larsen for
putting forward some great alternatives for fixed stops in the Enhanced System
Tester.
<SPAN
class=673253207-10082003>
After getting my
head around the code volunteered, I have found that your code, Roy, with the two
PREV functions gives me what I want and does not seem to slow my machine too
much when running through reasonably large databases ie
<SPAN
class=673253207-10082003>
A:=3; {ATR
multiplier}BC:=Cross(Mov(C,15,E),Mov(C,25,E)); {buy
example}SC:=Cross(Mov(C,25,E), Mov(C,15,E)); {sell example}<FONT
color=#ff0000>Trade:=If(PREV<=0,BC,If( {SC OR} {optional
sell}C<HighestSince(1,PREV=0,C)-A*ATR(7),-1,1));Trade<0;
<SPAN
class=673253207-10082003>
I specifically
wanted to hang the 3*ATR(7) stop from the highest high SINCE POSITION ENTRY and
the code does this beautifully and verified with a chart indicator showing the
code provided as a binary wave and also checking the results with alternate
system testing software. It also works if you allow pyramiding
of positions! It even makes money in this basic form!!
<SPAN
class=673253207-10082003>
Whilst I can follow
the above code, I am just a little unclear what the rule "PREV<=0" is
referring back to. I assume it is checking that the BC condition has not fired.
If you could give some clarification here it would greatly increase my ability
to use the PREV function in the future. I suspect other Metastock users in this
Group may struggle with this very important function also.
<SPAN
class=673253207-10082003>
Once again thanks
for the help. In the meantime, I shall be trying to incorporate multi-exit
conditions into the above code such as if the Chandelier Exit fired or a fixed
number of days has expired.
