We know that the main criteria is either oversold conditions to buy, or overbought conditions to sell. So for our long entries, I guess the market can get oversold, then more oversold. etc.

Who knows. I wouldn't be surprised if there were over a dozen factors that the system looks at. Anyhow, it might not be wrong yet, just very early.

So many people are buying into that Sell-in-May thing. It's not written in stone. And anyhow, someone provided a link to an article by McLellan which pointed out that in election years, after a Democratic president, the market Zooms up in June. McLellan's a pretty smart guy. 

Here's the link again, (but I wasn't the first person to post it).
