Hi

I am new .. just stated with JForex. I want to calculate a moving average and bollinger bands on Renko bars but I cannot see in the documentation a method to do it? Is it possible ?

Many Thanks

Paul

Hi

Great thanks ... so I would set up the feed descriptor in my start up method ... and use the listener as my on tick method essentially? And would I get an onBar event for this?

Thanks again

Paul

In a sense that onFeedData executes whenever a new ITimedData element gets formed - then yes.
No, you only need the IFeedListener.onFeedData unless you want to use both time aggregation feeds (i.e. one minute candles) and renkos.

Hi

Sorry I an not quite clear so the onFeeddata get called on every Tick or only on when a new renko is formed ? I am thinking I would use the Renko feed listener to identify a new Renko bar (in effect it is called when a new renko is formed [a renko feed!]) and I would use the tick event to handle individual ticks ... so in effect the renko listener mimicks an onBar ???

Thanks again

The latter, see:
https://www.dukascopy.com/client/javadoc/com/dukascopy/api/feed/IFeedListener.html
See the following examples, launch them both with live and historical data to see how they work:

Partially - renko listener is more precise, in the sense that IStrategy.onBar fires on a new bar for all subscribed instruments on all periods that have just been completed (e.g. at 12:00 completes not only 1H, but also 4H, 1M, 5M, 10M, 15M, 30M bars), but IFeedListener.onFeedData only fires on the completion of the particular ITimedData element of the designated IFeedDescriptor.

Hi

Great that is really helpful ... much appreciated ....

Best
