It's best to follow the SP500 rather than the Dow. The former is much more representative of the whole market. And it's best to follow market movement in percentage rather than points. Points inflate over time as the nominal value of the market indexes climb.

The DJIA is not as good a metric compared to say, S&P500. It considers a 1$ move in any of the constituents in the same manner, so a stock worth 200$ moving up by 1$ is given the same importance in terms of points change in the index value as a stock worth 2$ moving up by 1$ (whereas fundamentally speaking, the second movement is far more interesting than the first).

"point gains" is a vanity metrics. Percentage matters

and what's the 3 day / 5 day trend?

giant gains are not so important after giant losses, this is just celebrating volatility.
