If you view it through the eyes of big money, they always have to move the market. They have to pay huge carrying costs, millions a day, to keep the lights on and pay for those huge marble buildings. To stay in business, they use the models that have shown how to manage the markets in all conditions, studying what worked in the past 100 years, again and again, for maximum gain based on up and down markets.
They make money in all markets, they have to. Study their game, what they are really doing, and how they work through bear and bull. It gives you a model to mimic them, flip when they flip, and an attentive trader can make money every day, regardless of what the market does.
Technique matters the most, knowing how to flip with them. Probability is they always have to trade, they have no choice but to keep the market working for themselves, which means they have to keep traders coming in with fresh cash.
So, what are they doing today to accumulate (scare traders out), OR release profits (pump up the market so they can sell). That's all they do, every single day, in any market. Huge fortunes are created from every crash. That's the game. As Lenin said, "the worse, the better."
Happy trades!
