Title: Black Swan Events and Multiple Algos Post by: bb113 on June 24, 2012, 03:33:09 AM So there are at least a few people here running multiple models that they pick and choose to trade based on, whether using computers or elliot wave theory. Do the events of earlier today put you at a disadvantage?
It seems to me every time one of these technical difficulties occurs the market becomes "wary" and kind of resets, negating recent info that has been included in the models. I'm just interested to know how people deal with that situation.

You are referring to the unintentional halt in trading at Gox?

Title: Re: Black Swan Events and Multiple Algos Post by: bb113 on June 24, 2012, 06:19:54 AM The data from the trading glitch has actually produced some extra divergence in my models—half a percent or so. But I don't like to throw out data, it will take me a little bit to find a way to work it out. Thank you for your acknowledgement. I am 12 and appreciate it.

Explain it like I am 5... :P Title: Re: Black Swan Events and Multiple Algos Post by: bb113 on June 26, 2012, 02:27:57 AM I want to learn about Kurtosis risk!

Title: Re: Black Swan Events and Multiple Algos Post by: Raize on June 26, 2012, 02:41:21 AM Sorry, not picking on you, just pointing out the futility in trying to address some of the stuff. The problem is that the more accurate you want the information, the more technical it's gotta get, which is unfortunately the problem. I only consider myself slightly aware of some of these things, but doing research into why so many financial institutions like the Black-Scholes equation is a good start.
Fair warning though, it gets technical very quickly. There may be some Khan Academy tutorial that kind of gives a general overview, though. http://en.wikipedia.org/wiki/Kurtosis_risk http://en.wikipedia.org/wiki/Black%E2%80%93Scholes http://en.wikipedia.org/wiki/Delta_hedging http://www.youtube.com/watch?v=zFiGL7lxsxc Title: Re: Black Swan Events and Multiple Algos Post by: bb113 on June 26, 2012, 02:54:40 AM Sorry, not picking on you, just pointing out the futility in trying to address some of the stuff.

Title: Re: Black Swan Events and Multiple Algos Post by: TraderTimm on July 03, 2012, 07:46:43 AM Black-Scholes and the assumption of a (normal) gaussian distribution in determining option pricing is one of the major flaws that blew up LTCM. The 'mean' should be thicker than the 'tails', and most price action disagrees. The number of two to three sigma events fall outside of the 'predicted' distribution, which means of course any assumptions based on that model are doomed to tail-risk of large magnitudes.
BTC is probably a more 'sane' market that anything out in the traded exchanges, if only by virtue of not having a crapload of sub-pennying front-running High-Frequency Trading algorithms dominating volume like the ES futures or the major Index stocks. |
