Another funny one.. select avg(Price) from StockTickEvent.Win:time(30sec) I don't see the hard part here? :mad: Somehow the Nesper is opening my eyes a bit, well... thank you for that link. I will report back as I progress my journey into CEP. Feel free to post your thoughts about CEP.

Thank you for collaborating, I have looked at Streambase and to be honest... It looks like a long sales speech, not much value in their papers nor in their diagrams. I'm looking for something more technical; why is CEP interesting and what can it do that normal programming can't. Take for...

Ohh... that didn't occur to me :p Sometimes the gems can be hard to find in the search-jungle that's why I'm asking fellow traders :)

Hi there... Can anyone direct me actual case studies where CEP has been succesfully implemented And/ or Articles where CEP is described with trading in mind. Kind regards Janus

:D Rigth in my basement yeaahhh http://www.cisco.com/en/US/docs/solutions/Verticals/Trading_Floor_Architecture-E.html

Previously I have revealed that I was in the process of developing my own trading engine, but what a thread that became. A lot of smart-asses polluted my good intentions of sharing experience and knowledge :mad: Unfortunately this is becoming more and more normal here at ET to chase the man...

Yes.. I somehow over estimated the skills of people here in Automated Trading forum... I somehow thought this forum was for asking technically questions related to developing trading platforms, discussing good and bad things in the already existing packages, but I was wrong. I'm sorry I did not...

Well your posting is clearly expressing what you see in the mirror. No wonder that so 95% of all traders lose.

Just forget the initial question... I can see clearly now that the majority of people here are losing money, have no success in automated trading and just are being ignorant and happily calling all other for idiots. Find a mirror and look into your own eyes, think carefully about what you see.

Now we are talking... positive helping, I love it :) Please correct me if I'm wrong on this, but isn't a state machine performing some actions in response to some events. - I would think that the override methods would be appropriate for such behavior? i.e each time a tick/ trade / quote is...

Hello asiaprop, thank you for answering, well.. only one so far has misunderstood the question, but yes.. it could easily be me who wrote the original post in a wrong manner. Everybody is however still free to ask more thorough. I had hoped my question could open up for a nice discussion on...

The purpose is to override OnBarUpdated with some custom code.. It could be reading some indicator value defined in the StartUp, that of course is automatically updated.. So for instance: protected override void OnBarUpdated(Common.Entities.IBarData barData) {...

What? 2 things here... The first: Exactly that should be the purpose of a forum, help other and they will help you back. I just asked for input, the true power is hidden in helping and you will receive it ten times. But somehow you have forgotten why you are here, do you know it your self...

ohhh.. nothing like it outthere :D and never under estimate the power of doing the things by yourself. Many of the open sources have a nasty code smell that would be impossible for me to ignore.

Hi there... I'm in the middle of designing a piece of event-driven trading software and to keep a nice intuitive feel and usability, I have decided to listen to the voice of people. Feel free to help and NO it's not a new comedy of TickZoom and NO it's not open source at the moment and NO...

Maybe I will work for beer money, but I will not promise you anything before the first five :D

TradeBulk? TickFactory? TradeDesigner? DesignTrader? QuotePattern?

hello dear fellows... Does anyone have good suggestion for a piece of software that receives tick/trades in real time, event based aggregating, analyzing and submitting trades to various brokers? What do you think about QuoteTick? I've also thought about something like Aspergillus, but...

We are not talking about software packages, but about developing a system from scratch... and exactly at that point, you are being a bit ignorant for all the other things apart than some API that can give you realtime ticks.

And what about aggregations and volume distribution, stability and high performance? Thinking you are being a bit too much positive :)
