You're missing the point. You said the poster was stupid for not seeing the trends that happened in the ES yesterday. When most people look at that chart, they would call it a wide trading range. Of course there is a trend when going from the low to high and back to the low again. But this you only know in hindsight. If you're going to just use hindsight charts without any mention of what's happening in real time, might as well get in line with all the other fabulous hindsight chartists that ET has.
The thing about you is that what you say is all very good, but none of it shows any real trading ability. I can mark up trends on every single chart after the fact as well, but what does this prove? You don't have to make real time calls if you don't want to, but I think its important for readers to understand that you aren't really saying anything if all you ever do is talk about what happened. Imagine how smart I sound saying how the ES today trended very strongly from the open, hit its overnight high, and then trended some more on the way down. I'm a fucking genius!
The comment of mine you dug up stands on its own. I've never seen what a trader floor at the exchange looks like, nor do I have any idea what GS does or any other big firm. This is what I call professional trading. Even if you are the hottest trader out there, I still wouldn't call you a professional trader because you're retail trading your own account. To me a professional works for someone else, not for himself, but I'm sure everyone has their own definition.
If you want to know what impresses me, its this:
