<DIV><FONT color=#000000 size=2>I don't know if any of you noticed the recent 
article in Futures magazine about Bollinger Bands and the different applications 
for different time frames.&nbsp; In the article it was suggested that a 10 day 
moving average with a BB of 1.5 SD be used for the short term trend, a 20 day 
moving average with a 2 SD(the most widely used) and a 50 day with a 2.5 SD for 
the longer term.&nbsp; I think that a combination of all three is not a bad idea 
too.&nbsp; </FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT>&nbsp;</DIV>
<DIV><FONT color=#000000 size=2>What I think would be interesting would be an 
article on how to interpret the different hooks on the outsides of the bands and 
what these are implying statistically.&nbsp; For instance, looking at last 
October after volatility had been expanding for close to three months the lower 
band hooked back in, the market made a double bottom and we have not looked 
back.&nbsp; More recently, the upper band on the 50 /2.5 has hooked in during 
the Jan/Feb trading range and on this current breakout the band has hooked back 
up.&nbsp; Notice these similarities.</FONT></DIV>

<DIV><FONT color=#000000 size=2>Many different options trading strategies can be 
built around these bands and I think that they are a very interesting study for 
anyone interested in how the markets have this statistical bend to 
them.</FONT></DIV>

Dear RTs,

Many people like the use of large (19" or 21") monitors.  I do too.

I would expect large monitors also give out (exponentially according to size?)
larger amount of radiation.  But I am not sure.  People say sitting more than
6 feet away from a TV is safe.  But when we trade, we are only 2 feet from our
(multiple!!) monitors.  We don't want to get any excessive dose of radiation.

Would anyone wish to comment on the following:
1. How much radiation is acceptable in layman terms?
2. Larger monitor = how much more radiation?
3. When monitor has been in use for some time, older = more radiation?
4. Newer models = less radiation?
5. Which brands = less radiation?
6. Any radiation rating in the specs of monitors?  How to read?
7. When my screen-saver (blank -- black) kicks in, does that mean less
radiation at that time?
8. Safe distance from the monitor when in use = 3 feet?   6 feet?
9. Use of non-glare screen = less radiation?
10. Where to get the larger size (19" or 21") non-glare screens?
