Tick by Tick Correlation
Unlike binary options, which have an all-or-nothing payout at expiration, Nadex spreads move with the underlying. When the market moves up or down, the spread price moves in close correlation.
Nadex spreads are an innovation with unique benefits. They offer the same price action as conventional markets. But their built-in floor and ceiling mean that, while you can’t expect “unlimited profit potential,” you have risk protection that, unlike stop-loss orders, gives you staying power.
