It is just a well thought out exercise designed by OzWaveguy to study the statistical correlation between the post count and trend reversal patterns observed in the "How low can the All Ords go?" thread.
The key challenge is to keep these two thread active so that the data remains useful.
Yes but by deliberately posting in a thread for the sake of keeping it active you're invalidating the results, unless the relationship between post count and market activity is deterministic.
And if it is deterministic, everbody post in this thread until 31st Dec, buy lots of stocks and then only post in the "how low can the XAO go" thread (and don't tell anyone else about our little secret!)
