Hello,
Colors and rendition are 100% correct. Think about it. In
your formula color depends on CURRENT bar value.
So area between CURRENT and NEXT bar is plotted with selected
color. Now when
chart swings above your "borderline" the color changes from
NEXT bar and not in the "Middle" of the bars.
There is no way to specify time between bars.
StockCharts are NOT formula based. They hard coded fills and
the simply fill everything above border line with
one color and everything below border with abother
color.
To create such rendition is somewhat tricky because it
involves overlay of two charts and appropriate clipping of the
drawing
to "appear" as interpolated. This is also possible using
AmiBroker but this method has one problem - it is not
printer friendly because printer drivers and windows metafiles
can not properly handle clipping regions.
The same applies to colorizing Stoch overbuy/oversell
levels.
This is can be done using "secret" style
styleClipMinMax:
Stochastic color oversell/overbuy levels
SetChartOptions(0,0,ChartGrid30 | ChartGrid70 );
r =
StochK(14);
Plot( r, "StochK", colorBlack );
PlotOHLC( r,r,50,r,
"", IIf( r > 50, colorRed, colorGreen ), styleCloud | styleClipMinMax,
30, 70 );
Best regards,
Tomasz

Hi
Thomas,
I started using the
styleCloud. I like it for certain types of charts much better than
histograms but I see one issue with it – colors change with the change of bar
value and not with the change over or under a certain quantitative
value. For example, in the attached Chaikin MF(10) charts of WRES, the
AB version shows odd changes in colors, while the StockCharts version shows
the correct (IMO) rendition.
In the attached
ChaikinStyleCloud.gif chart, look at the 12/7 bar (under the cursor
line). The CMF(10) value for that bar is “-.07” (negative).
The 12/6 value is “.07” (positive). In the AB version, the cloud
color is the green color of the 12/6 (positive) bar even after the bar drops
below the “0” line between the 12/6 and 12/7 bar. In the
StockCharts version, the color correctly changes at the “0”
line.
Here’s the color code
for the chart:
CMFColor =
IIf(CMFI >=
0, PColor,
NColor);
Apparently AB
translates this as “when the bar CMF value changes to goes over 0,
change colors”. My preferred translation would be “when the
interpolated CMF value goes over 0, change colors. I need
to report this to Tomasz, but haven’t had the time.
It looks like a
similar issue. Is this the issue to which you were
referring?
Regards,
Dan.

Hello,
stylecloud looks good, however i have found no way to plot

on any indicator with cloud correctly.
Can someone help please ?
