Sad that a service which was a stellar resource as Daily Graphs Online has become less than reliable since changing over to MarketSmith.  I could not recommend a subscription to this site until they get their act together.

While MarketSmith management is madly scrambling to put together new bells and whistles to generate more revenue, reports that have had inaccurate data on this site for over 8 months are ignored.

When a phone call to tech support results in a brush-off answer to the problems, accompanied by a sigh which can only mean "jeez, another call on these reports, I'm getting tired of hearing this", you know there's a serious problem.

Ken,

 I'm aware of a few erroneous data points which have been reported by the community and to which MS seems to have repsponded appropriately.  You suggest the problem is more rampant and diffuse across the site.  Do you have examples?  Given the shear volume of data involved in equity research a few variations and even outright errors are to be expected IMO.  Thanks.  Brad

The most aggregious examples I'm aware of are
Option Implied Volatility - Lowest Short Term (30 Day)
and
Option Implied Volatility - Highest Short Term (30 Day)

MS has Long Term (1 year) version of both reports, which haven't had this long-term recurring problem.

For the Short Term (30 Day) versions, the following is what happens, over and over again:

MS puts in a temp fix - this holds up for a week or so, and the reports appear to be working.  Then the reports go haywire - they just list the same stocks, in reverse order.  That lasts for a week or so, then the number of stocks in those reports start dropping over a week or so, until there's only one stock listed in both reports - the same one, of course.
After several weeks of complaints, MS puts in a temp fix that lasts for a week or so.  Then the reports go haywire - they just list the same stocks, in reverse order.  That lasts for a week or so...well, you probably get the picture by now.

This pattern of "resolution" has been going on since at least April of this year.  I've given up on it, just accepted that these reports are useless and always will be.  Not a ringing endorsement for a service that charges $1,000 a year for data.  It does make me wonder what other ongoing problems are being deliberately mishandled this way, or are dismissed as being due to "proprietary data formulations".

These two reports settled down into 'one stock' mode on Monday Nov 14.  They'll be like that for another week or two or three, then the temp fix will be slapped on.  The problem will be declared as "fixed', the open tech support issues will be cleared as "successfully resolved".  And the cycle starts again.

@Ken_brun Thank you for bringing this to our attention. The Options Reports were refreshed over the weekend and are now displaying the correct data. We will continue to monitor the reports for any signs of regression and we apologize for any inconvenience this may have caused.

MARKETSMITH, Since you have indicated that you're monitoring the reports for signs of regression, I'm sure you're aware that these reports are once again going haywire.

I'm also sure that you will correct the problem (again) by throwing on the temporary patch (again).

The temporary patch lasted all of two weeks this time around.

Ken,

We are very sorry for the frustration caused by the bug in these two options reports – we know how important quality data is, and we pride ourselves on that. In response to your initial call we thought we’d resolved the problem. That was not the case, but we are diligently finding a final solution. We’re thankful for your persistence in bringing the issue to our attention.

We greatly appreciate your business and loyalty to MarketSmith. Please call Scott at 800.472.7479 at your convenience if we can be of further assistance.
