Re: [amibroker] coloring built-in Volume charts

[Frank <fesnay@xxxx>]

Try this:

upvol =
C >
Ref(
C,
-1
);  // todayVolume is higher
than yesterday
downvol =
C <
Ref(
C,
-1
);  // todayVolume is lowerr
than yesterday

barcolor =
IIf(
downvol,
4,
IIf(
upvol,
8,
9
)  );

/* Colourized price bars drawn here
*/
//Graph0BarColor = barcolor;
Graph0Style =
2+4;
// Bar Graph
Graph0BarColor =
barcolor;
Graph0 =
Volume;

//--Indicator-End-- -- do not remove this line
//Plot( Volume,"Volume", -8, 4 );

Two major changes -
the //--Indicator-End-- has to be AFTER all coding.
change the barchart to a histrogram.  That is the "2" +
"4" for fat.
