Thanks, Tomasz
Duh, sorry about that. I should been thinking more.

http://www.amibroker.com/ib.html (SCROLL DOWN to "symbology"):
ibc.PlaceOrder("ER2-GLOBEX-FUT", "BUY", 100, "MKT", 0, 0, "DAY", False );

Subject: [amibroker] IBController - Where do I specify exchange?
Using the demo code for IBController I can place orders with this
code
ibc.PlaceOrder("MSFT", "BUY", 100, "MKT", 0, 0, "DAY", False ); //
place order but do not transmit yet
works fine.
But if I want to trade futures where do I specify exchange? Just
changing ticker ("MSFT") with "ER2" it still defaults to "Smart"
as the exchange, when it should be "GLOBEX".
Thanks,
Bruce

Subject: [amibroker] Re: Backtester: same bar scaleout and sell
signals traced (2)
For the traces tried all SetBacktestMode parameters, including the
new
ones 2.
Also traced the signals delivered by the system, which are ok.
Those signals get transformed by bo.PreProcess() if on the same bar,
altering
backtest postprocess while leaving positions open.
Since scaleout is removed, to software trap the signals on a custom
backtester a workaround is required.
By chance, is there an undocumented 'transparent' backtester mode so
that PreProcess leaves signals
untouched for the custom backtester?
Thanks again.
