Re: [amibroker] Re: Graphing beyond the data, AmiBroker Email List Archive

Hello,

If you need calendar days, you need to use DaysSince1900 function instead of BarIndex().

So instead lines like this:

Line1_X = Cum(1) == SelectedValue(BarIndex())+1 + F5;

You should be using:

ds = DaysSince1900();

sds = SelectedValue( ds );

Line1_X = ( ds == sds ) + 1 + F5

As you can see instead of repetitive calls to the same functions (slow) I am using

variables. This makes code much faster.

Pit,

i spent sometime with wavemechanic (he's very clever) i put together a spiral ala Carolan but i'm afraid to say that the only way of measuring time was in trading days not Calendar days as per Carolan.I cross checked what i created with true Carolan theory and the error increased with the F series number.

sorry to be the one to bring the sad news as you can see from the code below i converted the F series into trading days to display a point and click forward Spiral.

All up at the end of the day it's not possible to create a point and click true Carolan visual Spiral as it's too difficult to count in calendar days,,i'll show the code i put together with Lal and Wavemechanic but please understand it does not correlate to a true Calendar Spiral

Hi

Is this possible to project Carolan windows/dates/ in the same way.

Best Regards

Pit

Robert and many of us want to do, is necessary to identify future
values for a variety of studies, including Hurst channel projections,
cycles, etc. Here are TradeStation examples showing the extension of
the analysis (not a shift) into the future.
