If not doing algo trading on spreads, pyramiding is the most aggressive and fastest way to make such profits. But it is highly dangerous and I know traders which do trade like this and as already told: Bang, with one trade all is gone as all is finally set on one card. A traders mindset do this people have, and what kind of it. But all the rest which is needed to survive trading is not there.
A friend of mine, which was a share fund manager in the past, did in the high tech bubble with his fund 160% in a few months. But when the bubble blasted, the fund lost in a few days half of it and later was even closed, as he not was enough educated how to hedge his fund and about MM. So nobody comes here to me to say: MM and strategies are just the little part of trading instead THEY are some most important parts of trading when it comes to the point to keep any money we made with trading. Having a mindset to be a trader is prerequisite as it is for any job and this is just the basic and not the main point.
