<t>Hi, guys, an easy problem for you:We have 10 people. Each one of them has to make a present to somebody else (not to himself), so that everyone will end up with one present from another guy from the group. After a valid draw in which everybody will get a present, which is the probability that at ...

I wear glasses, but my vision is getting worse every time I visit the oculist. I have read about this Bates method, which consists in simple exercises for the eyes. Anybody has tried the Bates method to improve his/her vision?

I know of a yoga teacher which is really serious. He gets up every morning at 4 a.m. and practices asanas for 2 hours, 1 hour pranayama, 1 hour meditation (daily!). Besides, he is vegetarian. He leads a normal life, is married, with one child. He has two jobs, and sleep only around 4-5 hours.

<t>QuoteYeah this is really important, I find a lot of people in the west (some Indians too, sadly) are modifying/extending yoga to suit themselves or cater to fitness fads. The other day I was reading about somebody conducting Yoga in a heated environment where you get to 'sweat it out' while pract...

<t>Any Wilmotters which practice yoga? Just taken a course and seems very interesting. After a session you feel much better. It seems that yoga is winning its place in the world as an ancient method of relaxation. Anyway, the classical and ultimate goal was the realization of the self (whatever that...

<t>QuoteSo, do we have a wannabe rogue trader in the making here or what? No, FDAXHunter. You have an exotic product and have no idea of certain parameter. No idea of its historical value, no idea about its market implied value. Then you try to be very conservative. The problem is that you may lose ...

<t>I agree mostly with you, but wanted to know the opinion of this forum. One simplistic argument: I think of the problem as if a have, for example, a call option in my book. I mark-to-market only 75% of it, giving value 75 for example. Therefore 25 is kept hidden. This corresponds to one quarter of...

3 points:- Sorry, I wrote too quick. I wanted to say marked-to-market instead of market making. - What is dV/dRho, variation of Vega wrt Rho? - I could not understand your opinion? Would we lose money or not? (at least theoretically)

<t>You are a trader and user of a model. One of the parameters of the model, say a correlation, is set very high: 95%, instead of a more realistic 30%. Imagine a deal is done. Market making gives you a value of 100, but instead should be 150 (you have hidden value due to the higher correlation). You...

Quoteit would depend a lot on the pay-off and the market state. Please, elaborate. We speak, for example, of a payer swaption NC 1 year, strike 3, with probabilities to be cancelled in year 1 or 40%, and in year 2 of 30%.

<t>Imagine you have a bermuda option with right to exercise at year 1, 2 and 3. You have a system with exercise probabilities 20%, 15% and 25%, being the probability of not exercising is 40%. Would you exercise this option, and when? Which is the "general" rule for exercise probabilities p_i with i=...

This may be a stupid question, but I do not know the rules of Liars poker. Could you please tell me. Also I would like to know any winning strategy for the game.Thanks in advance

Do you think this is a radical change: I have just changed from stocks analysis to fixed income volatility trading. Any recommendations?
