No, this is definitely not the case and we have verified this: 99% of today's values were between -300 and +250! It's almost as if the basket of stocks being monitored has changed, as if it's a much smaller number of stocks. You can verify this yourself by looking at this symbol: TISS-NYSE We have noticed a change and we do not know why. There have been no calculation changes. There is only a change, in the communication messages that now use doubles. We are continuing to look at this and do our best to understand it. We even considered, the comparison, to determine an uptick and down tick , with how many decimal places are being compared and we are comparing out to 4 places now. Previously we are not sure how many decimal places were being compared, because it was based upon data from the exchange per symbol or it may have been based upon Symbol Settings. We have to do more research on that. We do not believe there is anything really wrong. This does not mean, we are giving up on why there is a change. Although it looks like there is something wrong but perhaps it is just more accurate because we also noticed a similar change with a smaller range that happened when we switched data feeds going from a data provider, direct to the data feed from the NYSE. And the only way we could create a greater range was also to include bid and ask updates. And we did verify that those are continuing to get processed this week. We are actively looking into this.
