RE: [amibroker] Conditional looping question

I do not know Tradestation but I believe your solution lies with AB's IIF
function
(refer: http://www.amibroker.com/guide/afl/afl_view.php?name=IIF)

Something along the lines...

Period =
IIF(linearregvalue(close,Counter,-1)>linearRegValue(Close,Period,-1),
		 Counter,
		 Null/*or whatever the false value should be*/);

Hope this helps.

Subject: [amibroker] Conditional looping question

Dear all,

Is it possible to implement Conditional looping in AFL along the 
lines of the following. For example what is the most effective way of 
translating this Tradestation language example. ( I think.)

snip ---------------------------------
For Counter = 13 downto 7 Begin
 if linearregvalue(close,Counter,-1)>linearRegValue(Close,Period,-1)  
then Period=Counter;
End;
Cord=linearregvalue(Close,Period,-1);
---------------------------------

>From what I read I can substitute the appropriate AFL keywords (eg: 
linearregvalue = linearreg etc...

But how do you implement a conditional loop using arrays? AFL "if" 
command does not appear to operate on arrays only boolean values.

I'm sure its possible but I'm programmably challenged.

Regards,

Graeme Oswin
