So Im building a DOM ladder style interface for JForex and I have everything working perfectly data wise.
The ladder updates fast, and displays how I want.



Now Im just trying to get the orders to fire off and am finding it extremely challenging.

I can fire an order from inside the onStart, onTick, onBar methods just fine.

But I have buttons, and JTables, that when I click, I want to fire certain methods.
I have all the methods wired up, and they are firing just fine.
However...when I put an IOrder submit order inside any of the methods, I just get unhandled exceptions. No explanations.

I made the IOrder and IContext public, thinking that it was because I didn't have access to them inside other methods.
But still no luck.

Any idea how to put the IOrder inside my own buyMarket(), or closeAll() methods?

You have an issue with multiple threads of execution.

Java Swing callbacks for your widgets (e.g. Buttons) are happening in a thread of execution completely separate to the thread responsible for issuing orders to the Server.

This second thread is the one you see making calls to onStart, onTick and onBar, etc.

If you insist on placing orders from your own widget callback methods you have the option to use mechanisms provided to publish order requests into this second thread via the the IContext instance.

Take a look at <this> for some guidance on the approach.

Thanks, that helps quite a bit.
Im still very new to Java and am still learning
Coming from a javascript background, the strictness of Java is quite confusing at first.

Anyway...you said..



Were you implying that theres other/better ways to do it??

Also..should I be developing this as a standalone in Netbeans as a plugin, instead of building it inside of JForex as an IStrategy
Since it really isnt a strategy and more of a manual order entry widget.

Are there any plugin tutorials apart from the ones in the wiki??
I can't find much on how to implement a standalone widget

So I tried implementing a new thread and I get this error...

2015-07-21 03:59:05 Syntax error on token "start", Identifier expected after this token
2015-07-21 03:59:05 ^^^^^
2015-07-21 03:59:05 thread.start();

My code is straight from your example link.

final IContext finalContext = context;
Thread thread = new Thread(new Runnable() {
@Override
public void run() {
try {
finalContext.executeTask(buyOrder);
} catch (Exception e) {
console.getErr().println(Thread.currentThread().getName() + " " + e);
}
}
});
thread.start();

We could not reproduce the error. Please provide full code example.
