Sample Bid Ask at Nadex

For example, let’s look at a comparison of the bid and ask pricing at Nadex with an advanced option calculator. Do we get similar premiums? If not, why are there differences? By entering the key pricing information in the calculator supplied by Superderivatives, a world-class professional derivative option calculator, the result was different than the real-time Nadex premium pricing of the AUD/USD weekly 1.065 binary contract (Table 1.3), which shows a bid of 16 and an ask of 21.5.

TABLE 1.3 Bid/Ask Comparative Pricing

Contract	Expiration	Bid
AUD/USD >1.065(3 p.m.)	15-APR-11	16

In contrast to the Nadex real-time pricing, the Superderivatives engine using the same expiration date, (April 15, 2011) and binary strike price for the AUD/USD (1.6025) showed a bid/ask range of 7.75/19.75. At that same moment the same binary strike price on the Nadex platform showed a bid/ask of 16/21.5.
