Right click on DB plugin - works for RT symbols, not local ones (see docs!)

IBKR data plugin, 1-minute database.
The plugin is connected, but right-clicking options on the connection status stopped working.
Deleted the whole database and recreated it. Uninstalled Ami, removed the install directory, and reinstalled it. It still doesn't work.

Such questions are best answered if you send them to support (email support at amibroker dot com).

Please post a SCREENSHOT from
File->Database Settings.

and
Tools->Plugins

Go to File->Database Settings and make sure that "Interactive Brokers" plugin is listed and selected in the "Data source" combo box.

The thing is that something on your computer (like antivirus) might have actually DELETED the DLLs (plugins).

It happened in the past with certain antiviruses that have literally destroyed files on computers Bad Image (0xC000020) error - McAfee gone mad

More information—

A fresh install and database with 1-minute data with IBKR works; I can right-click on the connection and backfill.
The right-click breaks and stops working after any type of data import, either from AmiQuote EOD from the Tiingo API or from ImportWizard Tiingo API EOD CSVs. Either it breaks because 1-min and EoD data are mixed or data format. The "Allow Intraday and EoD" checkbox is checked.

Because you are NOT supposed to import ASCII data into real-time data source (driven by the plugin)

It is pretty obvious - if you feed data from RT data source (plugin) that is your source of data, not import.

It is explained in the guide in great deal of detail:

Quote:

Things you should NOT do, or you should do very carefully

You should note the fact that when you are using a data plugin, then the plugin controls the quotation database (see the Understanding Database Concepts article); therefore, you should NOT import quotes from ASCII files (this includes AmiQuote) for symbols that are already present in the real-time database.

If you do, the plugin will eventually overwrite your imports with the real-time data, or your database will become corrupted (if you import end-of-day data over an intraday database).

So please do not import ASCII (especially EOD data) into a real-time intraday database fed by the plugin.

You may ask why this is not disabled at all. The answer is that sometimes it is useful, and sometimes it will work (but these are rare cases). For example, it will work if you import INTRADAY data into the intraday database fed by the QuoteTracker plugin, and both the database and imported data have exactly the same bar interval.

It also works if you import the data for symbols that are not present in the database. In this case, newly imported symbols are marked by the ASCII importer as "use only local database for this symbol" (See the Information Window for details), so they are excluded from the real-time update. This is useful if you want to import some other data (even non-quote data) and access it via the Foreign function while using your real-time database.

So ASCII import is not disabled in a real-time database, but you have to use it with extreme care and know what you are doing.
