To seasoned Remek! traders, there's nothing new in this post. But everyone else should pay close attention:
If you understand why we have marked those circles and why one of them (today's session) is in thick, and why today's session happened the way it did, you've understood 80% of what it takes to play this game successfully.
And then you also understand that success is not in some magic "indicator" (indicating what?), but in understanding how the winners play this game, in other words, how they take advantage of crowd behaviour. Your success lies in understanding the winners' strategies and working around them. Let me say this again: you must work around large players’ strategies. That is your edge. (And our edge, as embodied in our algorithm.)
To make it short, if you understand the significance of those thick circles and those long bottom tails (remember: those long tails at one point today were totally red, totally scary sell-off candles until you-know-who did you-know-what from you-know-whom), and why they happened today, then you're ahead of most traders, and you also know what we can expect at 6pm EDT on the Sunday open and on, next week.
Those traders interested in the theoretical foundations of the above thinking and those interested in studying the markets for what they are, a constantly evolving ecosystem, are encouraged to check out Andrew Lo’s work.
