Hi all, I've been charting silver futures for a few months and playing with SLV options. I'm looking into trading options on futures, with the advantage of being able to set a stop and liquidate if the position goes against me overnight and not get slaughtered by the gap since the futures markets are 24 hours during the week. Are options on futures also tradeable on a 24-hour basis, or are they limited to the NYMEX hours? Or in other words, are there any brokers who give you access to options on futures trading on exchanges that are open when the NYMEX is closed? Thanks!
