Markus,
1. Yes. No need to modify JScript part
2. Add SetBarsRequired( 200, 200 ) at the very top of the
formula. This should resolve the problem.
3. It depends on your colors set in
prefs. If you use bright background use
Graph1Color = colorBlack; (at the end of the formula), if you use
dark background use:
Graph1Color = colorWhite;
Updated formula follows.
/* SWING CHART

SetBarsRequired( <FONT
face="Courier New" color=#ff00ff size=2>200<FONT face="Courier New"

Subject: [amibroker] Re: Canīt detect
proper cum values - attn. Tomasz
TJ,
the swing code works JUST FINE!!! Many, many
thanks!!!!
It still needs a few modifications on my part but
merely on how the swing conditions for HP and LP are
calculated.
Thus:
1./ Can I simply change the swing condition by
changing the condition for "HP" and "LP"? Or do I have to modify the jscript
part as well (unfortunately, have no expertise in this)?
2./ The swing lines seem to be calculated
"real-time" as one moves thru the chart. The last swing seems to be
imprecise plus "moves" up or down as I scroll forward. Is this
intended? Is there a way
to get rid of this (if desired) without the need for extensive programming? If
not, no major problem. This would slow down program speed,
right...?
3./ I have the "up and down bars" feature
activated in the preference settings. This seems to be disabled. How can I
turn this back on, please?
Great job this code!!!!!!
