I think you have to take ESR at his word unless proven otherwise.
currently he is offering price levels that he finds are important and that work for him.
trading and posting trades is difficult.
I am only here on the pages of ET when I either have a longer term swing trade in place or have no trades on.
I tried to post some of the short-term trades I do. to post and manage the trades, it is not worth it. It is not worth the aggravation of someone calling you a sham, especially if you're in a trade, it does not unfold the way you expected it to, you close out the trade at a price level that is neither your target nor your stop and because you posted the exit "after the fact" you lose credibility.
I'd rather lose ET credibility than real money.
