Fluctuation of spread

Hi i`m curious how you guys feel about spread.I dont know but for me its certainly low now at the end of the year.

I dont know if it is caused by the end of the year feeling, thus nobody trades the market so the spread is low.
Or it’s just a coincidence.

I mean spread is set after the volatility of the ticks, so fewer ticks in a given period of time meaning less volatility meaning the spread is smaller. So it could be that because the end of the year is near not many people trade now (especially the E/U), but the spread is unusually low.

Let me know what you guys think about it?

And NOTE i`m not talking about intraday spread, whereas the spread is compared to the LONDON-NY session ,when its the lowest, but rather comparing daily average spread.As of, since Christmas the daily average spread has been unusually low.

Any thoughts?
