Hi,

when applying Filter.ALL_FLATS in IHistory.getbars(...) I'm assuming that by definition there should always be bars in the return list.
The only case I can think of where no bars would be returned is if bars before the start date of the historical datafeed would get retrieved.

However we are experiencing the error message
"Number of bars to load = 0 or time is not correct time for the period specified"
when working with Filter.ALL_FLATS.

Example:

history.getBars(EUR/USD, TEN_SECS, BID, ALL_FLATS, 92, Wed 2010.01.06 00:00:00.000, 0)

There's also a question that arises when looking closer into filtering flats. If e.g. during the night on a lower timeframe (TEN_SECS, etc.) there are no trade ticks, but on the HOURLY there are, would getBars consider the TEN_SECS as being a flat that will get filtered?
I.e. with Filter.ALL_FLATS do you really filter all flats depending on the timeframe, or do you filter "MARKET_CLOSED"-flats?

Looking forward to you response!
Best, RR.

We have the following code inside getBars:

        if (!(period != Period.TICK && DataCacheUtils.isCandleBasicFast(period) && DataCacheUtils.getCandleStartFast(period, time) == time && (before > 0 || after > 0))) {
            throw new JFException("Number of bars to load = 0 or time is not correct time for the period specified");
        }

From this code you can see that the reasons for the error can be:
1. period is TICK
2. period is not one of the currently supported periods
3. time is not the start time of the candle
4. both parameters specifying the number of candles are zero

Code that you posted cannot raise this exception. Most likely the time that you passed in real code was not correct candle start time for the period

Dear support team,

thanks a lot for your reply and the info.
I thought I had taken the data used in the posting directly from our error log, but it's quite some time and versions ago, so I'm not 100% sure.
When now running the following code I'm getting the correct return list with 92 bars.

List<IBar> aBars = history.getBars(Instrument.EURUSD, Period.TEN_SECS, OfferSide.BID, Filter.ALL_FLATS, 92, fDateTime.parse("2010.01.06 00:00:00.000").getTime(), 0);                

So from my side we can close this topic.

Thanks and best, RR.
