Sure, my view works well in theory, but if we make it more reasonable, say gain of 5 pips, it doesn't change the fact that BO can produce more than spot.
Regarding the small difference in price and argument - argue what? Whether it's in the money or out of the money? I don't argue on the latter.
Thank you for your link, it was well known to me before, too, when I researched the topic! All in all everyone will make their own decisions, whether they learn from other people's mistakes or not.
For me, everything depended on how I chose to utilize my trading day, and I suffered way more requotes or even an inability to get into a trade with binary brokers versus spot. The starter of this thread must have an entirely different experience with offshore broker(s) than I.
