Neil/Reinsley,
I don't know whether this is what you are looking for or that you want
something different. Let me know. I have some stuff with foreign symbols
what might be closer to what you want.
Below the afl from Brucer/Bisto. Apart from minor editing nothing was
changed.
The Zoomer.
The Zoomer takes a little bit of getting used to, but the thing does work.
Create a number of windows: For example, 5 Min,15 Min and 1 Hr timeframes
(W1,W2,W3).
There are several modes: Zoomer On/Off and Single and Multiple windows
activated.
Zoomer On/Off: Zoomer can be activated in the parameter window. Each window
can be activated inividually. The Reset All button is somewhat misleading
since it only turns off the Zoomer in the activated window and has to be
repated for each window with Zoomer On.
Zoomer Off: Clicking in one of the three windows results in a synchronized
Selected Value Line (SVL) to appear in all 3 windows at the same time (of
course when out of view, scrolling is required). Time ranges can be selected
inidividually. Works fine.
Zoomer On.
One Window with Zoomer On. Zoomer On is selected in the parameter window for
the activated window. All the zooming action takes place from the activated
Zoomer window. After selection, the other 2 windows are adjusted such that
they cover the same time range as the selected window (its time range stays
unchanged). So in this example W1(5 Min) will have approximately 12X as
many bars as W3(1 HR). Changes in the visible range when made from the
Zoomer Window are all transferred to the other windows. So, the ranges of
the unselected windows are synchronized with the selected window if the
range is changed from the Selected Zoomer Window.
However, ranges can be freely changed in the windows with Zoomer Off from
their own time axis to look at other areas. Cursor synchronization can be
done from each window, regardless of Zoomer condition. Occasionally
Zooming doesn't work immediately: Click on the left or right arrows in the
time axis or on the time axis (or the title bar) and it will respond.
Multiple windows with Zoomer On. Initially I thought that multiple
simultaneous Zoomer selection would provide more flexibilty. However,
although on occasion there is the capability to toggle between the
pre-synchronization time range and the synchronized time range there are
also time axis issues, wrong and oscillating displays, so I stopped using
it.

Hi,
here I am with a slightly different Version of the BruceR's function to

Subject: Re: [amibroker] Maintaining cursor position between time frames
Joris,
+1
In a variation on the same theme, I made many attempts between floating
windows displaying two different futures. I was not successful, not yet...
Could you please share your code ?
Thank in advance.
Best regards
