Schadenfreude and sheer boredom
Schweiz...your response doesn't make sense. There can be advantages like attracting capital, emotional rewards (like an ego boost) from showing a P&L.
If someone is 'for real' they should have no issue with showing you the objective numbers. I am not talking about their trading strategy (that can be a trade secret) but their risk adjusted P&L.
Because I like to take the piss and find it amusing. Schadenfreude is always fun if a little cruel. Also I like being cynical rude and sarcastic.Why are you still here?

Why are you still here?
Ha ha. Sure. The fun thing is you'll never know whether I am a sad loser like most people on trading forums or someone who has had the sheer luck to make a few Bob and keep it. That's the magic of the internet - full of sound and fury signifying nothing.Maybe because like most traders (as they tell) he ran out of luck and lost everything?
The truth has a funny way of setting you free. Also, it helps you make decisions better.Maybe they didn’t know how to short? ROFL
You can do it again.I left investment banking aged 34 and made a fortune flipping IPOs. There was no skill involved and very little work. That was in 1992. I spent many years living in Switzerland skiing every day in the winter and hiking in the summer. I would flip IPOs as soon as they started trading and often put the sell orders on by mobile phone from my snowboard.
From about 2003 I wasted a great deal of time backtesting trading strategies and looking on on forums. It was for a few years that I realised forums were puss and wind and populated mostly by fools.
I am aware that I will win few friends with my comments. Most people just don't want to face reality
I made a great deal of money when the dice were heavily loaded in my favour. That's how you make money. I was a legal version of Bobby Axelrod in a small way. We had 30 traders and in good years turned over 1bn USD. Sadly those days are long gone.
