I see trading as an art and science. I utilize objective charts and levels, etc., but often I will react in opposite manners to situations that look very similar. The art is the years of experience that gets you beyond just a knee-jerk reaction. I remember in Nov. 1980 I really knew nothing about technical analysis, sentiment, etc., but I started messing around with call/put ratios. I'm not sure when Marty Zweig developed his call/put stuff, but I was looking at option tables in the WSJ and wondered if there was a correlation between the volume in calls and puts. There seemed to be, and I thought I had found the holy grail. I did a few things with the ratios to adjust them for outstanding open interest, because it occurred to me that if there is more open interest, then there will be of necessity more trading as a result of the larger open interest. I made a bunch of money going long and short in that time period, and then one day I had it "all on black" and Joe Granville issued a sell signal, the market plunged, and my Federal Express options were sent from 3 points in the money to 4 points out of the money, or something like that, with one week to expiration and I was ruined. Learned a lot from that. For one thing, there is no holy grail. The other thing is, losses are important, and you can learn a lot from such mistakes. The other good result is that, because I was wiped out, I couldn't marry my at the time girlfriend, and I'm really glad of that.
