The main rule is never post an "after-the-fact" call even if it was the best trade of your life. If you did not mention it before it moves, then you can't mention it at all. Otherwise, if you do mention something that qualifies as an "after the fact" call then you look silly and lose credibility as the people on these boards are smarter then you think. For example, on a certain board I saw one poster who said they stopped out of an ES position at 1152 some days ago. Then they posted today they are 20 points up on the ES and had loaded up on the FAS yesterday. Oops, too late. Since he did not post that he entered before the move, he cannot post later on that he owns the security or future. One tactic of shills and hacks on the web is to post after the fact. You dont want to be mistaken for one of them... To sum up...make a post BEFORE you make the trade. Posting after the stock has moved makes you look foolish and opens you up for questions and criticism from other posters.
