Here is more specific about checking and cleaning EOD data I did in my program, easy and hard bad prints, etc. I saw the following bad prints actually in yahoo and google historical data, and other sources. All the following can be automated: 1. bad zero vol - zero vol is normal for many etf and...

Considering missing data on some days when comparing multiple historical time series, this is a common issue. What I do is simply to normalize the time series by forcing them use the same time array either adding missing daily data or by removing unwanted daily data from some of the time series.

That is exactly I saw. I asked data cleaning questions but not actually got any good response. Simply talking about historic eod data from many sources, bad prints are everywhere.Many of these can be detected easily such as some out of band prints, but a lot still hard to pick out. Anyway, do...

Looks Cramer was right at that time but who knew when gold was down.

Actually, there are many traps in the back-testing. historic data, time frames, time ranges, data quality, subjective selection of markets, stocks, and errors in using historical data, software problem, etc, these are all problems that causes often too-good-to-be-true results.

In short term, seriously, I see space exploration technology stocks will hopefully get a boost. This should last for a really long time. For smart traders, some time in the future, they can do stock trading from the alien earth because theoretically they can see the future from that really...
