Published / Preprint: A Market Model for VIX Futures. (arXiv:1504.00428v1 [q-fin.MF])

A new modelling approach that directly prescribes dynamics to the term structure of VIX futures is proposed in this paper. The approach is motivated by the tractability enjoyed by models that directly prescribe dynamics to the VIX, practices observed in interest-rate modelling, and the desire to develop a platform to better understand VIX option implied volatilities. The main contribution of the...

Published / Preprint: A Markov model of a limit order book: thresholds, recurrence, and trading strategies. (arXiv:1504.00579v1 [q-fin.TR])

We formulate an analytically tractable model of a limit order book on short time scales, where the dynamics are driven by stochastic fluctuations between supply and demand, and order cancellation is not a prominent feature. We establish the existence of a limiting distribution for the highest bid, and for the lowest ask, where the limiting distributions are confined between two thresholds. We...

Posted: 02 Apr 2015 02:56 AM PDT

Banks are being hacked all the time.  According to various statistics, banks get over a million cyberattacks a year, and protecting the bank from breach is getting harder and harder.  This was well illustrated by the Kapersky report of a cybercrime group in February gaining access to over $1 billion in two years by targeting over 100 banks in 30 countries. read more...
