Quote from makloda:
You just do it. What is the problem?
Scalability is not a problem. You just don't only use fundamentals but you use technical factors in your decision making.

You have lots of instruments under your management and you do charting for all of them? Or you rely on a computer to do programed technical analysis unsupervised? And inevitably, you order will move the price because you are a big player then. The noise will easily affect the tech-oriented program's decision making...
