There are many similarities between poker and trading and the best financial day traders look at trading like a business and not just buying and selling shares. They are also aware of the practices of other trading firms and traders and can manipulate them to a large extent. In fact this is a constant battle that is also apparent in poker as well. As your opponents increase in complexity and sophistication then the margins decrease. By that I mean the edge that you have in certain games.
Playing many tables at once is sort of like automated trading on the exchanges. The firms that take this route usually go for volume with a very low return on turnover. In fact a 0.5% return on turnover would be huge if your turnover was say 100 million. That would mean an income of $500,000 per year. Many financial trading firms go down this route but to do that then you need very fast execution along with an automated trading system.
This philosophy applies equally to online poker because when you play higher levels then you are coming into direct contact with players who are not only far better but who will be watching you far more closely and adjusting to what you do. So you need value to come from somewhere and if you can play in a way that prevents you from making big mistakes then you could be playing poker in a style that can make you money as long as you have a solid style if play to begin with.
