RE: [amibroker] Keeping a counter

["dbw451" <dbw451@xxxxxxxxxxx>]

Thanks Graham.  One thing I love about AFL is that many of the functions can
be written in AFL itself.  While not usually the smartest thing to do, it
sure provides a lot of flexibility whenever one wants a function to operate
a little differently.  :-)

 

Regards,

 

David

you could always use the straightforward way

cntr = cum(sell);

Alex,

 

This works exactly the same way in AFL:

 

Cntr = 0;

for (i=0; i< BarCount; i++) { 

       if (Sell[i])

              Cntr = Cntr + 1;

}

How do you do this in AFL?

I want to keep a counter variable that adds 1 everytime a Sell=1. In 
VisualBasic it would be:

cntr = 0
for i = 0 to barcount
if Sell[i] = 1 then cntr = cntr + 1
next i

cntr then becomes the number of trades that have closed. For example, 
if there were two trades in the backtest, cntr would be 2.

Thanks - Alex
