Subject: NH NL rising
Going through the last 20 years with a focus on the seasonal indicators, especially for a 529 account that only allows 2 trades per year.

I saw the rules laid out by Mungofitch and saw that he used the 5 and 17 EMA.

But then I found some links pointing to a 10 & 42 EMA.

1. What's the difference?

2. Has the seasonal effect still been working?
