High Frequency Algorithms, they are called and they are the ones used by the whales or institutions that move the market to make their operations. These programs are expensive but they gather a great deal of information, they know where every penny is, they track every order, meticulously. And they indicate who is more leveraged and who is less, and where they are located. In other words, whoever does not know this reality is really lost.
Information: well, I have a theory about this. No news moves the market, unless it is something unpredictable. Like the Twin Towers, to give you an example. And here there is a lot to cut through. The market is moved by the whales and they agree to give the news that they already know a long time in advance. Information is power. Never better said.
The less you are in the market, the better; the less you are leveraged, the better; as long as you have a plan and always, always stick to it even if the world is coming to an end, the better. That's the only way to win there.
