IG Markets is the corporate sister of Nadex. They offer spot forex trading along with forex binaries and options to US and international traders. Along with the "ladder" binaries that Nadex offers, IG Markets offers daily and monthly OneTouch binaries, as well as Up & Down binaries.
OneTouch binaries settle immediately as soon as the underlying security hit it's strike price. Up & Down binaries are simply a wager as to whether the market will finish above or below the prior day's close at the end of the day. Please see the Nadex page for a detailed description of how ladder binary options work.
IG Markets also offers traditional "vanilla" options for forex, silver and gold. The trading interface is nearly identical to Nadex, and you can even switch between IG Markets and Nadex's offerings on the trading screen. Please see the Nadex page for more information on the trading interface.
The margin requirements to trade options on IG Markets is higher than for Nadex. An IG Markets option contract is $10 a point. The smallest contract size you can trade is 0.2, which is $2 a point. Instead of charging trading and settlement fees like Nadex, IG Markets takes their commission directly from the Bid/Offer spread.
If you like the flexibility of having additional types of binary options, as well as spot forex trading in the same account, then IG Markets may be a suitable option. An IG Markets account allows you to trade Nadex as well. IG Markets accepts US and international customers.
