In my experience, people tend to ask for advice to a wide audience on a position when it has been making money. Typically, the position will then rapidly reverse after said announcement. Well, that's been my experience anyway, so I don't do it any more.
Irritatingly, I find that when people ask how my trading is going, it's usually when it has been going well. However, my telling them my trading is going well also precipitates a sudden reversal......
In summary, I'm relatively happy to let people know when I'm losing money (although only if asked by someone I know, I hardly want to broadcast it) but I keep schtum when making money.
