It appears to me that blue traverses for both MELI and SOLF charts have been constructed using this same approach (above).
Hey All, Long time lurker that has begun paper trading Jack's pvt method on equities. I have a question about some data. I went on vacation and missed watching the market last thursday and Friday. I noticed last night when I took a look at last friday's data (6/27/2008) that there was what seemed to be HUGE volume on friday for most of the final universe stocks. I mean like over 4/5 of the stocks had greater than avg volume days (which is not normal), and alot of them had absolutely HUGE volume compared to their average. In looking at the intraday vs daily volume I saw some discrepencies, and looking at Yahoo it seems like volume is just out of whack. For instance, there was a nice discussion about MELI last week and into the weekend. Avg Volume for MELI according to yahoo is about 1mil. Volume on last Thursday was 1.215 mil and volume on Friday was reported as 2.35 mil. More than double the avg volume, howeve I don't see any great price swing. Looking at the 5 day graph on yahoo in 5 minute bars, the last bar has a reported 1.26 MILLION shares traded! That seems bogus, especially considering the last bar had very little price movement. To me this doesn't make sense. Its also wierd. Using pvt, having screwed up volume really messes things up. I can't tell what is in dryup, and it is really hard to pro rate volume based on previous day volume when previous day volume is all whacked. I am not paper trading today, becuase I don't trust the volumes reported for last friday. A quick check shows that other final universe stocks seem to have this same issue (SCOR, DDS, STAR, CAVM). Anyone else notice this? I notice the MELI chart posted by Spydertrader and others had the whacked volume. What do yall do when you think your data is whacked? I have only been paper trading for a month now, are these kind of data issue common? Do they eventually get corrected? Am I just totally off base? BBQ p.s. Thanks to Spydertrader and all the others that have contributed to this and the other journals. This and the other Spydertrader journals are quite simply phenominal!
