following up, realizing I didn't really answer any of your questions...
"Are you getting timestamps to the second for your executions?"
Answer: yes-to the second, just like Ameritrade.
"What do you do if you're travelling and need to make a trade by phone?"
Answer: For some reason, I have Fidelity, Tradingdirect, Ameritrade, and Freetrade accounts. I'd use one of my other 3 accounts, but this may be a problem for someone who doesn't have
anything else.
Not sure about your other questions.
