Did you actually read that: http://www.amibroker.com/ib.html from the start to the end ?
 
It says:

As for "automatic backfill on first data access" - when it is checked AmiBroker attempts to backfill symbol when you display a chart for given symbol (or perform backtest or scan). Please note that TWS API currently allows only one backfill at a time so when there is a backfill already running in the background, automatic backfill request for next symbol will be ignored, until previous backfill is complete.

It is convenient to have this option turned on, however it can cause additional load on your internet connection because of data needed to be downloaded during backfill process.

If you switch "automatic backfill on first data access" option off, you will still be able to backfill data for current symbol or all symbols in real-time quote window list usign appropriate menu options from plugin status menu.

Backfill Current option allows to force backfill of currently selected symbol, while Backfill All RTQ symbols allow to force backfill of all symbols listed in Real-Time Quote window. Backfill of multiple symbols is performed sequentially (one at a time) due to limitations of TWS.

During backfilling a tooltip pops up informing the user about symbol being currently backfilled and plugin status color changes to light blue (turquoise) as shown below:

The only solution I?ve found is to put all your RT symbols into a watchlist and set the automatic analysis window to scan that watchlist every 1 minute. With every scan 1 more symbol will be backfilled . Once a symbol is backfilled it will be kept current with RT quotes.

I have too many symbols to put them in the real time quote window.

I tried the Buy = o; and that only back filled one symbol. But I
tried this during trading hours. Should it be done after hours?

Thanks,
Barry
