Are you using the OHLCSeriesCollection class as your dataset? OHLCSeries allows you to add new items.

I use custom DefaultOHLCDataset with added List field.
I will test OHLCSeriesCollection, thank you for help.

I tested OHLCSeriesCollection, it is functional, but loading performace is bad.
You can implement List<DefaultOHLCDataItem> to ie. DefaultListOHLCDataset?
I can send you source code. It is little change and somebody can use it...
