Re: [amibroker] Plotting Vertical Lines at fixed interval, AmiBroker Email List Archive

Paul,

Good to know this thread is helping you as well. Normally, I wouldn't hesitate to put up the entire AFL code here but there are some aspects of the code that might infringe copyright (the code is based on a published work). I will try to obtain the author's clearance - if received, I will place the entire code either here or in the Amibroker library.

In the meanwhile, if there are bits of your coding that you need help with, there are plenty of generous folk here who'd be glad to help (even I might :-) )

Cheers,
Lal

I followed this thread with interest and even managed to plot a small Gann Spiral working backwards in time from the the current bar,,,but i couldn't peice together this thread due to lack of coding skills ,could one of you post the result please,,,

i understood Lals question about ploting the cycle from a chosen "click" on a selected bar and would like to do similar with this Spiral but unsure how to ,,,and i'd also like to be able to run this Spiral forward in time too from a selected bar which i think Lal is working on now,

i know what i want to do i just don't know how and have progressed heaps since this thread started,,

please continue with the thread or feel free to contact directly.

regards

Paul,,,,,

Bill,

That worked very well. Solves the problem 100%! Thank you for the kind help.

The one additional thing I would like to do is plot the vertical lines beyond the last bar (Barcount() ). But let me struggle with that!

Regards,
Lal

Just replace cum(1) with (cum(1) - selectedvalue( barindex( ))

Bill,

Here's the screenshot showing how the vertical plots appear. As you can see, the vertical lines appear at a regular interval, but necessarily from the selected bar. What I desperately want is that from the bar which is currently selected, the vertical plots should appear on the right at the specified interval (calculated by the AFL itself, which is not an issue).

My understanding is Cum(1) counts the bars right from the very first bar for the ticker. That might explain why the plots appear in the wrong place. Can we solve this by other means?

Thanks,
Lal

Bill,

Thank you for the response. I've incorporated your suggestion and it does seem to work. However, there is a slight problem. Will post again with a screenshot showing what is happening. But I think we're nearly with the solution!

Thanks,
Lal

Nope, got it backwards:

plot(iif(barindex( ) >= selectedvalue( barindex( )), .....

Bill

Try this:

plot(iif(selectedva lue(barindex( )) >= barindex(), cum(1)%20 == 0, null), "", color, stylehistogram| styleownscale) ;
