Eugene, it is hard to prove the benefit of combining spread trading with book trading without actually doing it. I think spread strategy can benefit from some of the indicators available in JBT and vice versa. It does not make sense to keep the two types of approaches separate, because they are complimentary. All JBT indicators zoom in on market sentiment. Spread trading indicators zooms in on relative valuation. When both types of indicators say "buy", the security is both, undervalued and market sentiment is turning in its favor - should be a far more consistent performer than separately.
Ability to maintain a market neutral exposure is also very important. In any event, I will stick around. ________________________________ From: nonlinear5 <[email protected]> To: JBookTrader <[email protected]> Sent: Mon, November 15, 2010 9:06:49 AM Subject: [JBookTrader] Re: Live Trading Journal > Eugene, now that the JBT performance is so good, can you update Jarbitrager or > add spread trading capability to JBT? Astor, I know that you've been advocating merging the capabilities of JA and JBT into a single framework, but I believe they are conceptually different enough to evolve independently. Over the life cycle of JBT, I've quite religiously resisted the functionality which I believe to be "bells and whistles". That includes support for other brokers, database storage, command line and batch processing, portfolio management, and various third-party packages for web console. You can browse these features here: http://code.google.com/p/jbooktrader/source/browse/#svn/tags/jbooktrader-fg-0.3 I am a big proponent of simplicity. Reducing the JBT code base makes me happier than adding to it. I'd much prefer to have JBT defined and developed in a narrow scope, with the small, compact, and well- understood set of features. In the end, my purpose is not to maximize the user base, but to maximize the code efficiency in the sense that would allow me to use JBT to accommodate my trading strategies with the smallest effort required to maintain and evolve the code base. Now, I fully understand that everyone's approach to trading is different. It may be well be the fact that combining spread trading with the limit book trading is beneficial. However, until proven so, I am not willing to put my efforts into it. I hope you stick around, Astor, as you contributions to both JBT and JA have been valuable. -- You received this message because you are subscribed to the Google Groups "JBookTrader" group.
