Re: [amibroker] Difference between values (newbe Q)

["Joe Landry" <jelandry@xxxxxxxxxxxxx>]

Not sure about your questions but usually if I'm in doubt about whether something is working as I think it is, of if I'm interpreting the function or use of function correctly, I use the "old" Explore trick.  You'll see here that the lastvalue is indeed the last value of, in my case the slope of the end of day data in my database;  and b is equal to bv at the last element.   

Hope this helps

P = ParamField("Price", -1);

b = LinRegSlope (p, 5);

bprime = LastValue(LinRegSlope(p,5));

bv = LastValue (b);

Filter =1;

AddColumn(p,"Price");

AddColumn(b,"Slope");

AddColumn(bv,"LastValue of Slope");

AddColumn(bprime,"LastValue of Slope");

Subject: [amibroker] Difference between values (newbe Q)

Hi,

I'm newbe in AFL. Sorry for "stupid" question.

I have some lines of code:

....

P = ParamField("Price", -1);
b = LinRegSlope (p, 60);
bv = LastValue (LinRegSlope (p, 60));

...

I know that b is an array and bv is a numeric value. But why b <> bv?
Even sometimes b > 0 and bv < 0 (or opposite).

I check vslues with _TRACE function and DebugView.

Regards,

Piotr Rysak
