Two instances Amibroker - same database, only one updates?

AmiBroker

Setup details
Amibroker version: 6.22
Windows: Win 7 64bit
Data: Interactive Brokers real time
Data Exchange: ASX (Australia)

I just discovered my daily charts are significantly wrong due to the exchange sending through a final closing price for a key index about 15 minutes after the market closes at 16:00.

If I set the End time to 16:15 to include and display the correct closing price, my intraday charts have extra bars in them and indicators don't display correctly.

Question
Is it possible to run two instances of Amibroker simultaneously where:

  1. both read from the same IB intraday database
  2. only one updates the IB intraday database
  3. each instance of Amibroker has different settings in File > Database Settings > Data source

Instance where database updated by Amibroker (used for intraday charts)

2018-02-22%20-%20Snip%20-%20005

Instance where database not updated by Amibroker (used for daily charts)
2018-02-22%20-%20Snip%20-%20006

  1. each instance has different End times set in File > Database Settings > Intraday Settings > Trading Hours

Instance where database updated by Amibroker (used for intraday charts)
2018-02-22%20-%20Snip%20-%20003

Instance where database not updated by Amibroker (used for daily charts)
2018-02-22%20-%20Snip%20-%20004

Any thoughts much appreciated.

TWS only allows one connection per client ID. Since client ID is configurable per database, you can not feed two instances sharing one DB.

Tomasz,

I planned to only have one instance of Amibroker connected to TWS (point 3 above) and was thinking that setting 'Data source' to (local database) might do that.

If I also do not configure the Interactive Brokers plugin on the read-only instance, will that solve the problem?
