Dukascopy pricefeed in custom client - Java / jQuery UI Designers needed

Hi,

I'm working on the following project and maybe someone is interested in joining in. I could use a coder or two which are fluent with Java or even better jQuery/CSS UI Design.

What? Custom Java or if it can be done jQuery/CSS/Ajax UI to a MongoDB database holding a realtime Dukascopy pricefeed.

Why? MT4/5 is much too slow + the pricefeeds are way off & the indicator engine is very crippled. Other comparable solutions are not flexible enough from the programming side of things. JForex got a nice pricefeed, is responsive but the indicator engine is like even 100x worse than MT.

What am i working on?

What i have done so far is creating a server component which connects to Dukas over the JForex API and pulls the universal timeframes (tick/secs/minutes/h1/... - not H4/H8/Daily...) pricefeed into a MongoDB database in realtime on tick changes. This information is UTC timestamped. The non universal timeframes like H4/H8 and so on which are different for every trading session (e.g. London Pivots vs. NY Pivots) can be generated on the fly.

Plan is also to offload indicator calculations to the server like MAs, Pivots and so on to keep the client offloaded from that as much as possible. This is still dynamic from the client side. If the client requests a MA that is not yet in realtime calculation mode on the server it gets added to the list which the server calculates in realtime. Includes garbage collection of things that are not used anymore. Concurrency will either be done over java threads or outsourced to gearman jobs. Not decided on that one yet. Processing power is cheap. Realtime + Failover counts.

So what needs to be done is a visual metatrader like interface to that data.

If any UI people are interested, drop me a note.

Have a good one

Lazy bastards

Mission accomplished.

For anyone interested:

JForex API onTick() data generates realtime UTC bars into MongoDB database -> output of non standard bars (H4, etc) can be adjusted to any trading session.
Don't use IHistory! Unreliable, slow, broken. Generate the bars yourself out of the ticks. Calculate start of bar with help of Calendar class, check if it exists -> update ohlc or insert new one. Catch onBar() events in case no ticks are received to insert flat bars. onBar() always fires even if a bar does not contain ticks. Can also be done on non standard periods via IBarFeedListener.

Backend calculates dynamic list of Indices, MAs, and certain indicators serverside for each bar realtime to offload client. Can easily done in Javascript on clientside - i like to offload as much as possible to the server. Indices should definitly be calculated on the server side like USDX etc.

nginx+php-fpm+apc+vpn+https/tls serve it out to jquery/flot again. Modify to only submit latest bar. Gzipd even a shitload of charts fits nicely over a mobile line. Nice realtime charts with indicators, no flash, no java nothing and most important JForex pricefeed.

Performance in chrome multithreaded: excellent. Faster than any charting out there. Galaxy S2 is also more than able to handle it.

Todo: sync drawings server-side.

Hello

I would like to design the similar solution. Could you recommend the developer who built this for you?
sorry I still can't pm you.
