Re: [amibroker] Equity() Command

Ken --
It appears that Equity() uses some of the AA settings, 'Range' being one of them (I don't know about others).  Your friend may have had 'Range' set to the last day or something similar.

I would like to be able to define 'Range' in AFL using SetOption() or some such but I don't think it is possible right now.  I hope I'm wrong, and if so, someone will set me straight.

I understood the Equity() command to act as a builtin Backtest.
 
Accoringly, I create the following simple code to create and plot the Equity.
 

E5    =  EMA(C,5);

E45   =  EMA(C,45);

 

Buy   =  Cross(E5,E45);

Sell  =  Cross(E45,E5);

PlotShapes(Buy*shapeUpArrow,colorGreen);

PlotShapes(Sell*shapeDownArrow,colorRed);

Eq    =  Equity();

 

Plot(Eq,"Equity",colorBlue,styleLine);

 
I loaded this into the Indicator Bulder, and applied it and got my Equity plot.  No other steps required.
 
I shared the code with a friend.  He did the same thing, applied it, and got an {Empty} array and no plot.
He loaded the code into the AA window, clicked Backtest, and the plot of Equity appeared.
 
Question:  why did the same code act differently?  Next, will it be necessary to run the backtest every day to update the Equity curve?
 
Insights and suggestions will be appreciated.
 
Thanks,
 
Ken
