But, there is no chance in trading. There may be factors unknown to you, but that does not make it chance. Everyone is placing conscious bid/sell orders and the bots are running according to algorithms dependent upon set parameters.
What's the weather going to be like in six days?
(Traders still don't outperform chance. If you want to claim they do, please point to relevant data)
The weather example is irrelevant. You don't need to know what the exact market value will be to make a profit. You just have to know which direction it's going.
I'm in Chicago. We just got out of a very warm front and a cold front is moving in today. It has been over 90 degrees the last few days. I predict the weather will be cooler than 90 degrees in 6 days.
And, I predict it will be even colder in 2 months from now.
About 90% of my trades have been profitable ones. I've made approx. 30-40 trades on tradehill. Try flipping a coin 30-40 times and see how often you get 90% heads.
