<FONT face=Arial color=#0000ff
size=2>Jim,
the 30
in vol_avg is the 30 day moving average of volume. Not sure why you are using
ref here which references yesterdays value but it was in the original code. The
30 in X refers to the look back of the HHV (highest high value of volume over
the last 30 bars).
<FONT face=Arial color=#0000ff
size=2>
The
number of look back days in the HHV function is not based on the number of
default bars you load (you said 210) but more on the number of bars you
generally VIEW, If you like to see 3 months of data then set your HHV value to
around 60. Better yet I will add a param statement that allows you to easily
,make adjustments. just RT click the indicator and choose Param to adjust the
setting
<FONT face=Arial color=#0000ff

The
errors are caused by misplacements of the brackets. Try
this....
Regards,
Jayson

PMTo: amibroker@xxxxxxxxxxxxxxxSubject: [amibroker] Re:
Cutting off volume spikesJayson,This is much
closer to what I want. If I change the 2's to 4's, that's what I had
in mind. Can you explain what the 30's are describing? As a
reference, I have default number of quotations per chart set at
210.Now, I tried to retain my original bar coloring scheme, and add to
it bars which would be colored blue if your conditions were true. I
got error messages all over the place. Here's what I
created:Vol_Avg = Ref(MA(V,30),-1);PlotColor= IIf(V >
(4*Vol_Avg),colorBlue,IIf(C > O AND (C > Ref(C,-1))),colorBrightGreen,
IIf(C < O AND (C < Ref(C,-1))), colorRed,
colorYellow);X=Ref(HHV(V,30),-1);PlotVol = IIf(V <
(4*Vol_Avg),V,x);Plot( PlotVol,"Volume",
Plotcolor,styleHistogram|styleThick);The problem is in the PlotColor=
line I think. I want the volume bars to be BrightGreen if the Closing
Price is greater than the Opening price AND the Closing price is greater
than the prior Closing priceI want the volume bars to be colored Red
if the Closing Price is less than the Open price AND the Closing price is
less than the prior Closing price.I want the volume bars to be
colored Blue if they are chopped off.I want all other volume bars to be
colored Yellow.Is that possible? That's what I was trying to tell
it when I changed your PlotColor= line....Thanks for your
help.Jim------------------------------------------------------------------------
