I am currently searching the trading calendar of stock exchanges in the US. But different countries have different practiceS in trading. For example, in Australia, ASX is for listing and trading; while CXA is only for trading (not allowed to list companies). I searched from internet; there are three main stock exchange at US which are NYSE, AMEX and Nasdaq.
I have few question about US stock exchanges:
- Do three stock exchanges have same trading calendar and same settlement schedule?
- Can stock list at one exchange, for example AMEX, but trade at both AMEX and NYSE?
- Is there other listing exchange at US?
- Is there other exchange only for trade but not listing at US (like CXA at Au)?
