I found this for crude oil:
NYM CRUDE OIL CRUDE OIL FUTURE NYMEX CL 12/2016 02/2017 3,200 USD 0.1
NYM CRUDE OIL CRUDE OIL FUTURE NYMEX CL 03/2017 03/2017 3,200 USD 0.06
What does that last column mean? I can select maintenance, volume or scan.
Also, the start and end period is by month. Is there a more specific date and time that the contract period ends and the next one starts?
I believe that it stands for Maintenance Volatility Scan and that it's how much they move volatility in SPAN margining when shock testing portfolios. If your not trading options, you can ignore this.
Those are contracts. So the first line applies to Dec16, Jan17 & Feb17 futures. The second line applies to Mar17 futures. The further out you go the less volatile prices are and hence the lower the margin requirement is. As those contracts approach expiry though, the margin requirements go up.
