IB plugin blackbox

Swing has full drag/drop not sure why you need that ? I've used it in a previous projects for JTrees e.t.c

So I have the back testing coded but have run into problems thread wise. Mainly with the persistent layer and Entity Manager. Should have that working this week. Note there are at least 2 threads per symbol you are trading + the UI thread and broker interface thread. Then there are listener threads that run for error handling.

It failed running 20 symbols at once with a second delay on each candle. Runs fine in real time with 20 symbols but the test facade cuts out the broker delay.

Currently my approach is to persist at the thread level so each thread has a session context.

You might find that network latency is a much bigger problem.

1 thread may do just as well.
 
Sounds really good!
Would it be possible to interface to the AmericanBulls.com site to auto trade their signals?

p.s. I meant drag-and-drop GUI design, within the IDE, to layout the screen controls..

Eclipse does have a GUI layout plugin and Google also provide tool kits to do this. But for me I have enough experience that I can stack the layout managers in my head!! Eclipse will come with a layout manager in the next release.

One thread would not be much use when back testing. All the latency is not network as I run the App on on a local network. Now if your talking Latency from TWS to their servers well there's not much I can do about that.

I had it running this afternoon with around 45 threads with 20 symbols drawing the charts(candles every 1/2second), running strategies and managing open positions. Didnt get any DB locks so I think I have that nailed for back testing (yes realtime threads not the issue). Remember my strategies are for candle stick charts on a 5min basis. So the chart updates are 5sec.

Now need to run more testing. I also found updating an order in TWS works fine for single orders but with OCA orders it always tries to update the last order of the two even though I send the order id of the first. So I had to cancel and resubmit as a new order. This is a pain as I end up creating alot of orders in my DB.

Anyone found this and is there a solution ?

The way I have it designed you could interface to any data provider who can provide mkt data and has an API to send orders to. You just need to implement the functionality the app needs via the provided interface.
