GEN: Volatility

I'm not an accomplished analyst.  I'm a system trader.  And my 
systems have been getting whacked for the past month, mostly due to 
volatility.

It seems to me that the volatility has really increased lately.  In 
the S&P there have been 6 15-25 pt swings, in less than an hour, in 
the last 6 days.  None of them follow through with any kind of move.  
10-20pt gap opens have become common.  The ND is even worse.  

This raises hell with a short-term system that holds overnight and 
capitalizes on more sane moves.  The market settles down for a day or 
so, lulling my system into complacency so it takes a position, then 
wham!  There goes a 20-pt explosion, and I'm hit for another loss.

Can someone comment on this?  Do you expect this level of volatility 
to continue (or increase!?) for the near/forseeable future, or is 
this a short-term aberration?  My system has never seen anything like 
this in its 3+yr history, encompassing several hundred trades.

I can adjust my system to behave better in the market as it's acted 
for the last several months, but I'm nervous about changing something 
that has worked well for a long time.  But if this market is going to 
keep acting like this, I need to change something or I'm going to be 
in deep trouble.

For sure I'm going to have to start taking smaller positions, so at 
least I can go broke more slowly.... :-(
