would be nice to have an example of lazy loading data for the Candle Series (CandleSeries<Candle, DateTime>) Because the newly loaded records are inserted into the front of the list at index 0, effectively shifting all indexes so when we call "updateDataSource" it seems quite confusing on how to populate the addedDataIndexes and updatedDataIndexes to trigger a reload.
