Question about one trategy applied to multiple instruments

[appleseed]

When we apply a developed strategy to an Instrument, I configure from Control Center where select individual instrument. Can we select multiple instrument here?

From the section describing multiple frame or instrument, there is an example to add a multiple instrument by using add() function. Is the hard-coded instrument the only way to apply one strategy to multiple instruments?

protected override void Initialize()
{
Add(PeriodType.Minute, 3);
Add("AAPL", PeriodType.Minute, 1);
}

appleseed, the strategy would always have one primary series, for a multi series script you would then need to add in another series like shown with the Add() method and allow for example the selection of the instrument as string type user input.

Another option is to start a strategy on a instrument list from the strategies tab, however this will create an individual strategy instance for each symbol (so no MultiSeries script).

Thanks for clarification.
If I use your suggested method to "start a strategy on a instrument list from the strategies tab", each individual running strategy won't communicate between them. For instance, order filled info from strategy A won't pass to strategy B, correct? But at least all strategies will share account size (available fund) info, right?

Correct, there would be no strategy communication between the instances then.

If you scripts run on the same account, then they would share the GetAccountsValues from it, yes.
