I see; the problem was BarsSince was returning an array; not a scalar as i thought.
Ok, let me put another question out: I am using a 300 bar time stop using the following two lines at the top of my program: nBarStopValue = 300; ApplyStop( stopTypeNBar, stopModeBars, nBarStopValue ); In a for loop i am then defining my Buy,Sell,Short,Cover rules. And finally i am plotting arrows onto the graphs using PlotShapes(Buy * shapeUpArrow + Sell * shapeDownArrow , IIf( Buy, colorGreen, colorRed), 0, IIf(Buy, Low, High) ); PlotShapes( Short*shapeHollowDownArrow + Cover*shapeHollowUpArrow, IIf(Short, colorRed, colorGreen), 0, IIf(Short, High+6, Low-6 ) ); Since the time based stops are not part of the regular Buy/Sell rules, they are not being printed out on the chart when i am printing those arrays. So i tried changing the Sell/Cover arrays using Sell = Sell OR ( BarsSince(Buy) == 300) ; But this doesnt seem to be getting those signals in; my time based exits are still not being printed. ps: a. The backtester is picking up the stops as i expect them to; just that i am not able to plot them onto the chart. b. since the array version is not working; i tried to use a simple counter variable named myBarsSinceBuy and tried to count the bars myself after i got an entry signal; but in the couple of hours i had to play with it i couldnt get it to work yet; but thats another story. thanks again! -gariki --- In [email protected], Tomasz Janeczko <gro...@...> wrote: > > Hello, > > Please read the manual : > http://www.amibroker.com/guide/a_mistakes.html > > > Best regards, > Tomasz Janeczko > amibroker.com > > On 2010-05-09 10:20, gariki wrote: > > > > > > I am trying to put in this line of code > > > > if( LongEntryPrice > 0 AND (BarsSince(Buy) >= 300 ) ) > > > > > > and its giving me a compile time error saying: > > Error . > > Condition in IF, WHILE, FOR statements has to be a Numeric or Boolean > > type.. for the BarsSince function. > > > > BarsSince(Buy) should return a numeric value and comparing it with a > > number should return a boolean value. > > > > Does anyone know why it is showing up as error? > > > > Thanks > > -gariki > > > > > > > > > > > > > > > > > > > > > > >
