One of my best days in shorter duration bets at the bucketshop. (I hold an account at one in addition to NADEX). 19w / 5l / 2 scratches. ~2.4x with very moderate position increases.
I'm wrong. I have a habit of only quoting those at the open of each hour's bar, when in fact they're 2 hour options. So theoretically it could have been ATM or better.
