hi,
I believe because break has only recently been
added in the beta version of Amibroker along with "switch" and
"continue"
Further the code I posted earlier I adjusted a
little. I post it because somebody asked for it. Triggerpercentage on the short
side was not implemented properly,
rgds, Ed
waitPeriod = 10;
triggerPercentage = 0.02;
SetupLong = ExRemSpan(C < BBandBot(C, 20, 2), waitPeriod);
SetupPriceLong = ValueWhen(SetupLong,H) + ValueWhen(SetupLong,H) * triggerPercentage;
Buy = Cross(H, SetupPriceLong) &&
BarsSince(SetupLong) < waitPeriod;
BuyPrice = SetupPriceLong;
SetupShort = ExRemSpan(C
> BBandTop(C, 20, 2), waitPeriod);
SetupPriceShort = ValueWhen(SetupShort,L) - ValueWhen(SetupShort,L) * triggerPercentage;
Short = Cross(SetupPriceShort, L) && BarsSince(SetupShort) < waitPeriod;
ShortPrice = SetupPriceShort;
SetChartOptions(0,
chartShowDates);
GraphXSpace = 5;
Plot(C,"C",1,64);
Plot(BBandBot(C,20,2),"",colorGold,1);
Plot(BBandTop(C,20,2),"",colorGold,1);
Plot(IIf(BarsSince(setuplong) <
waitPeriod,SetupPriceLong,Null),"",colorLightBlue,1);
Plot(IIf(BarsSince(setupShort) <
waitPeriod,SetupPriceShort,Null),"",colorLightOrange,1);
PlotShapes(IIf(SetupLong,shapeSmallCircle,0),colorYellow, layer =
0, yposition =
L, offset =
0 );
PlotShapes(IIf(Buy,shapeUpTriangle,0),colorLightBlue, layer =
0, yposition =
BuyPrice, offset =
0 );
PlotShapes(IIf(SetupShort,shapeSmallCircle,0),colorYellow, layer =
0, yposition =
H, offset =
0 );
PlotShapes(IIf(Short,shapeDownTriangle,0),colorLightOrange, layer =
0, yposition =
ShortPrice, offset
= 0
)

Subject: [amibroker] Re: Looping - our
previous discussion
Ed & GP,
In the code posted here there is a 'break' keyword. I
presume its
function is to exit the loop when the 'if' statement becomes
true.
My question:
The editor highlights 'break' as a keyword, yet
it is not listed in
any help searches that I can find.
Would either
of you kindly point me to where the usage of 'break' is
defined in the
manual.
Thank You,
Ed Hoopes

Possibly I made some error there I am not sure. I wanted to
check if I
was maybe overlooking some error and that would be a problem
since I
use similar coding in the system I trade with and didn't notice
any
problems.
