Email interface versus DLL interface

[ThePatientOne]

I currently have several TradeStation strategies created that I would like to have execute via NinjaTrader. Two questions:

1) Is there any advantage to re-writing the strategies to use the native NinjaTrader DLL ATI interface versus using the email interface?

2) How does one go about having the strategy execute orders against multiple accounts? (both, via email interface and the DLL interface)

Ultimately, I will be moving these over to native NT strategies but current limitations in NT strategy execution are preventing this. So for now, I want know what I should be doing with my code for the best execution.

Thank you.

1) You do more better control over your orders with the DLL interface and more features as well (e.g. start ATMStrategies) at the expense of editing your TS strategies.
2) You can address multiple accounts with both interfaceses. DLL interface = by parameter, Mail interface + by worksapce. Pleaser consult the docs for details.
