Hi zaysev36,
I'm slightly surprised by your comment, as that's not my perception at all. If you read the
Is Trading the Same as Gambling? FAQ, you'll see there are lots of members who think they are the same, or at the very least highly correlated. Personally, my view is that it depends upon how you define gambling, and that doesn't necessarily have anything to do with subjectivity. It might do, but it doesn't have to.
As dbp regularly points out, if you have a well researched and tested trading plan, than randomness - in terms of your response to what the market throws at you - is pretty much eliminated. I daren't say completely eliminated, as there's always some eventuality that crops up once in a blue moon that even the most meticulous plan won't have factored in. As for the uncertainty, that too shouldn't be a problem for the same reason, as it is negated by the certainty of your trading plan. Needless to say, the theory is the (relatively) easy part. Having created your plan to overcome the randomness and uncertainty, you then have to execute it flawlessly. That's the tricky part and, for many, the stumbling block that leads to their undoing.
Tim.
