I really appreciate your help in getting this sorted out—it’s great!

So I’ve moved the logic to the IRangeBarListener.onBar method, as you suggested, and when I run the resulting strategy (attached) on a 5-pip Demo chart (starting at 14:31:58 chart time today), it does indeed print out values for each bar, which is splendid! But alas there are still two problems:

1) [Moved to another topic]

2) Every 10 or 20 bars, the printout shows an error message like this:

Many many thanks,

I could isolated this bug.
If you run the following strategy you will get the following error lines after some minutes to hours (depends on the market) in forward test. Backtest looks good.

Please correct asap, I need this proper functioning.

Bug seen in JForex DEMO version
Dukascopy ver. 2.15
JForex API ver. 2.6.63

Hi Support,

I’d really appreciate knowing when you’re likely to get round to fixing this bug. It doesn’t happen all that often, but when it does, a strategy will miss a whole bar, sometimes with disastrous consequences. Quite a few of your clients evidently use range bars, and until this is sorted out, they’ll always be working with a time bomb that can go off at any moment.

Looking forward to hearing from you,

Bunyip

It is fixed in API 2.6.67

I’m really sorry to say it, but this bug STILL does not seem to have been fixed, so please take this thread out of ‘Fixed Bugs’.

If I run the strategy ‘MacdEmaOnFeed5’ (see the posts on bug 3778: ‘Further feed problems’) on a 5-pip chart in the Historical Tester, any attempt to calculate an indicator from the datafeed now gives this error: ‘Passed Time [1970-01-01 00:00:00.001] has to be in interval’. For what it’s worth, I haven’t come across this problem on a Demo chart, and the passed time seems to go up by one millisecond for every successive bar in the Historical Tester.

I’d be awfully grateful if you could get this issue sorted out in the very near future. It’s over a month since I first brought it up, and the response to bug 3819 shows I’m not the only person who needs a solution.

Best regards,

Bunyip

What version have you checked?

Whatever was current yesterday. But the problem's still there this morning with version 2.6.69.

We cannot reproduce the following issue. Please provide us with detailed steps and a sample code.

As far as I can see the issue is now fixed in version 2.6.70, both using the Historical Tester and using a Demo chart.

Bravo and many many thanks!

Bunyip
