Hi,
Backfill means "filling your chart" with historical data for a specific period. All you can do with DDE is to get CURRENT realtime quotes, store them and good. If you switch off your computer on Monday, turn it on on Tuesday, you won't have data for Monday, no way to get it from your DDE source/interface. However, you can import historical quotes MANUALLY if your server has historical data available in ASCII format, e.g., and you can download them. With your provider, this seems to be the case, but it's quite a hassle updating the database manually if trading say, 1min charts. An elegant solution is the COM interface, that several providers, e.g. Esignal offer. AB has a dedicated Plug-In for each provider in the list. Backfilling data with the COM/RT-plugin is not a problem, however, it'll require you to spend a little money on a monthly base.
