IB - bundled vs unbundled

3)
Do you have a list of exchange which will charge for order modification and/or cancellation?

From the table, I see it list 3 types of orders which incur such charges.

- US Direct API stock orders
- US Direct/Smart TWS + API option orders
- Eurex option and futures TWS and API orders

Any others?


4)
I'm not really sure what Direct / Smart / API / TWS are.

Is Direct / Smart?
Is TWS your Tradestation Platform?
Is API something to do with autotrading?

And it appears to me if I trade US stocks & options, or Eurex option and futures, I will be charged for any modification or cancellation fees, right?

Or not since I'm not an exchange member?



Thanks a lot!

Is it possible to partly join "unbundled" for some products/markets, partly join "bundled"?

Too bad!

Thanks for the excellent advice!
You are so helpful.
