I noticed a week or two ago when looking at that WSJ page, for Nasdaq data it would sometimes show new highs and new lows as say 58 and 1100. Then I would refresh the page, and it would something like 24 and 175. Refresh again and it would revert to the previous numbers.

I think it’s also affecting Pinnacle data. Their data on the days with the odd refresh behavior appeared to combine the new highs from one update with the new lows from the other.

Below is an example of peculiar data. Even though the market on the 14th opened 12% above the recent closing low, held an intraday low 2.5% higher than the previous day’s low, and closed higher overall, the number of new lows still rose sharply compared to the day before.
day before.
