I strongly advise not to go down this path or any other inter-process communication. Make it simple and it will be very fast. Do not over complicate. I read gziped csv files with daily tick data. One file per day per underlying. Such a file usually has about a million ticks (quotes and trades)...

Trade around some mean-reverting process. This is actually the way most of big players trade apart from pure arbitrage. You need to do your homework to find one. I guess a good example is atticus's pitchfork - http://www.elitetrader.com/vb/showthread.php?s=&threadid=244704&perpage=6&pagenumber=1

Almost never happens with indexes. Vols rise with underlying falling. It behaves more like sticky strike. Almost never happens - vols fall with underlying rising. Same as stocks. Not that different. Index is just a few stocks traded in one basket.

It's somewhere in between sticky strike and sticky delta for indexes. Most of the time it's behaves as sticky strike. Anyway, you buy back month where skew is less negative than front month. Vols rise with the market falling - how would you lose on vega? No it's hard to lose on vega being long...

It definitely does apply. Why do you think it doesn't?

No it's genuine. I knew that most replies will be sarcastic and that's all-right. I have some spin off ideas from nazzdack's post. Thanks, mate ;) Keep it going guys! I need more ideas!

Thanks, Traveler. However someone who I know already founded a prop trading company with the name ending in -dyne so I'm reluctant to follow the case ;)

Please suggest a brand name for a trading software house - we are going to release our cool options trading software and the brand name is the major thing holding us back. We can not decide on the name! The software is for professional options/volatility traders, along the lines of Orc, Actant...

You can be net long options but still short gamma. E.g. ratio/back spread. So it's not just for precision, it's to remove confusion.

I've done that. My multi-leg execution strategy does not pay the spread, it trades on theoretical (fair) values on average. It quotes the legs and trades a spread maintaining vega-neutral exposure while executing. My backtester simulates execution of quotes/limit orders very accurately...

I would like to display options chain for indexes on my site (I will add some columns etc. so there will be some added value). I can start with one index whatever cheaper to display be it RUT, S&P, ESTOXX, whatever popular. The data could be EOD or some snapshot from today or yesterday. Can...

I guess this is true for any language if you have proper infrastructure. At least it takes similar time with Java for me.

I've done it with Jetty + jQuery for now, polling once a second. Works good enough. Will upgrade to websockets later. I reverse-engineered OptionsXpress page with live options chains to get some insight into how to do things. Their code is easy to read. I'd recommend looking there as a...

Thanks mate, interesting stuff. Reading up on websockets now. Where did you use python and rabbitmq in web interface? What's audubon technologies (the last link)? Is it your site?

I'm going to build a web interface to my trading server written in Java. The idea is to have a web page with live options chain where prices/greeks/other stuff is shown for monitoring purposes. I think of embedding Jetty into my java server app and use jQuery to fetch data and show it on a html...

Means he sells naked puts and delta-hedge them. Correct me if I'm wrong. His writings are sometimes cryptic for the experienced as well :D

I don't think kapw7 actually meant it. I think he is trading long vol + gamma scalping. He does not want to be long options at a lot of strikes, instead he wants to hedge delta and restore gamma/vega when underlying moves (and it will if vol rises).

It's called hedging. You basically called everyone who trades stock to delta-hedge an option a moron :D It's called replication. The OP wants to replicate a delta-neutral straddle using vanilla options. There's nothing wrong with this. It's just a a different type of trade from what you are...

Yes, it's hard to beat Kospi options on liquidity. All atm/otm options are quoted with 1 tick spread in front month. You don't need to convert to trade if you are with IB. But you would want to convert proceeds back to your home currency after you close a trade.

I trade Kospi.
