Hi RTs,  

Thanks for all of you who responded to my option question!  

I was very poor at placing stops when I started trading in 1995. 
Sometimes, my buy stops got filled at the daily high and my sell stops
got filled at the daily low.  As I gained experience, I am improving my
skill.  

I avoid placing stops 3 or 4 ticks above previous day's high or below
previous day's low.  But the problem is not completely solved.  Today,
my stop loss order (buy stop) was touched (Cotton, CTZ9) at 5630, which
is today's high.  I felt flattered and sad at the same time.  Look at
today's high, I know it was me, my stop order being touched.  Without my
stop, today's price history might be different.  I feel like a genius
who can forecast the daily high but unfortunately in a wrong way.  I
feel very bad.  I guess my experience is rare because it is very
difficult to get filled right at daily high or right at daily low.  

Maybe option is my only saviour.
