Even if I understand the concept, I am not familiar with ETF and I have some question about them:
1) It seem the price of fund as RYDEX are available 1 time by day for the transaction, it is the opening or the closing price is used for that?
2) On the website of RYDEX I have seen 2 prices (AM & PM), does these prices are available live in platform as IB? Terra Nova?
3) Since only one price is available, do you have to route on specific market (AMEX, SSOES, etc)?
4) Can we sell in extended hours?
5) when are you confirm for a trade, at the end of day?
