Edward:

I have attached the monthly QQQQ chart (AMIBroker version 5.1) that I get using Quotes-Plus.  I have compared it to another charting service I use and it looks to be the same.   The problem I am having is with volume as can be seen in the chart.  Here is the volume AFL code:

_SECTION_BEGIN("Volume");
Plot( Volume, _DEFAULT_NAME(), IIf( C > O, ParamColor("Up Color", colorGreen ), ParamColor("Down Color", colorRed ) ), ParamStyle( "Style", styleHistogram | styleThick, maskHistogram  ) );
_SECTION_END();

If I use abs(volume) in the code instead it keeps volume positive but I still don't see the sharp volume spike that you do in late 2008.  In fact my volume dips down in this area.  Your volume looks like it is correct when compared to my other charting service.

Can anyone help me solve the volume inversion problem properly?

Alan,

hi,

 

does anyone use Quotes Plus EOD data and also have a problem with the display of monthly data?

 

I use Amibroker 5.29 Beta and find on both computers where I am running QP there seems to be a faulty compression with monthly data. I checked with the helpdesk but sofar this problem has not been confirmed.

 

Attached an example of how it looks. Since I find this on 2 computers it seems to be a problem maybe with 5.29 beta? Could someone check? I tried opening a new database but to no avail.

 

thanks, Ed
