...still crickets? Anyway, I've been researching NADEX too. Mostly it's still crap. The daily binaries for SPX and DOW seem to be the only ones with spreads consistently 5 points or less, so I've been focusing on those. Papertrading a mean reversion strategy using the binaries that seems to be working. For example, yesterday SPX/DOW touched off support early on then rocketed higher, so of course buying the binary near the range worked well. A futures contract would have worked better to take full advantage of the trend. Today, no trend. SPX faked a sell off then reversed higher, but this time price just went back into the range and chopped around for the rest of the day. I "bought" the 2352 daily binary near the range @ 61. Interesting watching the binary over the next couple hours as time decay increased price into the 80's even though SPX didn't move much. By 1500, the binary was trading in the 90's. I decided not to wait for expiration but "sold" @ 94 for a $33 profit. Pretty cool considering SPX went nowhere today. Cheers!
