Hello

I am looking at the numberOfCandlesBefore output on the MA indicator using renko bars. The javadoc defines it as "numberOfCandlesBefore - how much candles to load before and including the candle with time specified in the time parameter.

I have run a simple strategy to print ema values when a new candle is printed and it seems like the output does not include this candle. See attached chart print and print output below.

Am I doing something wrong. Is there a workaround?

Please go through the following checklist:

Consider the following approach for indicator value comparison:

Many thanks for your help so far.

I looked through the wiki's and checked charts params, gmt issue and used OHLC. I still think the same... I have recreated the problem I am having... I think the onBar print is out by one candle.
When the 21:38 bar was printed, the onBar print was for 21:00 as per results below, which are from OutByx file attached.

Results summary are


index//time//ema//onBar print statement match (see log - OutByx)

85//21:38 // 1.02774 // none
84// 21:00 // 1.02776 // [0] 1.02776
83// 21:54 // 1.02782 // [1] 1.02782
82// 21:53.363 // 1.02785 // [2] 1.02785
81// 21:53.361 // 1.02786 // [3] 1.02786

This is the same problem experienced by dyscan in post of 18 Jun, 2012, 23:14 - viewtopic.php?f=7&t=47370&p=65115&hilit=simple+renko#p65115.

Is there any way to get the extra data - can I use candleAfter?


Also in the log file you will see some 'LoadDataAction' error. Not sure how to deal with this.


Hope to have this resolved soon.

Yes change candlesAfter to 1, because in IRenkoBarFeedListener.onBar you receive the bar that just has finished - the new bar has already started to form.

Thanks

If I change candlesAfter to 1, is the output still in the same array and at [0]?

Just test it

Hello

I still have the same issue. I have set candlesBefore = 2 candlesAfter = 1, LAST =2, PREV =1 and SCND_LAST =0.

A the formation of the current 'open' candle, the print statement is for the previous candle with the values commencing from this previous candle. It must be possible to access the current EMA as the value is shown on the hart.

Can you pls assist.

Pardon, where is the problem and what is the question?

The question is, how do I get the ema of the current open bar and not the previous bar. I am using the attached code.

either by calling indicator with shift=0 or with your current approach, take the following element: maOutput[maOutput.length -1].

Sorry and thanks for persevering ... but I have have printed maOutput[maOutput.length -1] and it's the same as the EMA of the last bar and not current - see below

2012-07-06 08:50:09.343 ma output line for last 3 range bars: [1.0272535151446864, 1.0271930464587282, 1.0271406402642311]
2012-07-06 08:50:09.343 1.0271406

And bizzarely, sometimes they are elements from 2 bars back. Like just now I get

2012-07-06 08:56:48.425 ma output line for last 3 range bars: [1.0272925174909227, 1.0272535151587996, 1.0271930464709595]
2012-07-06 08:56:48.425 1.027193.

I am not sure if this has anything to do with it, but if you look at the table data for the renko feed, the bar at 2012-07-06 08:56:48.425 has an open and close price of 1.0268, which is incorrect.

But my main problem is still, I cannot access the current ema.

Hello

Is there any feedback on this?

This should get fixed with JForex-API 2.6.73

Great - Moosic to my ears. Dare I ask when 2.6 .73 is scheduled for release.
