That part is clear, thank you for clarification. Amibroker calls GetQuotes(Ex) to get data for ticker A, that's OK. How do I backfill ticker B if Amibroker does not call GetQuotes(Ex) for ticker B? The reason for doing this is I want to let the user specify a list of tickers which should be updated realtime. Eg. a daytrader trades a few stocks only, but he usually scans hundreds of stocks. How can I backfill these hundreds of stocks? Upon performing a scan or backtest or walk-forward-test or I-dont-know-what, does Amibroker calls GetQuotes each time or how to provide data? Thanks lukit
