There was a thread that was posted that asked why traders don't share details of their strategies. I was going to respond to that thread, but I don't know where it is. The basic premise of my reasoning/theory is, The Red Queen: http://en.wikipedia.org/wiki/Red_Queen If you can understand that, you don't ever need to ask that question again. This is not grounded in speculation. It is grounded in strong scientific theory of complex systems. nitro
My question would be: why DO traders ever share strategies at all? Don't kid yourself, we are all each others' competition. Do armies share their strategies with their enemies? ... not successful ones.
My strategy: I look for stocks that are cheap and I buy them with the intention of selling it at a higher price. Sometimes I find stocks that I think will go down and look to short them and buy them back cheaper. That's my strategy. Hope it helps.
I remember in the movie "Patton" , Patton yelling: "Rommel, you magnificent bastard - I read your book!" and then going on to defeat him... http://www.imdb.com/title/tt0066206/quotes
If you had a formula to turn lead into gold would you share it? If you did then every tom dick and harry would turn lead into gold and then gold will be worthless. Same with trading, if you find a good arb opportunity or a strategy and it had a strong positive success rate, guess what happens if you share it?
