Barrier option

Any number of different option structures (such as knock-in, knock-out, no touch, double-no-touch-DNT) that attaches great importance to a specific price trading. In a no-touch barrier, a large defined pay-out is awarded to the buyer of the option by the seller if the strike price is not 'touched' before expiry. This creates an incentive for the option seller to drive prices through the strike level and creates an incentive for the option buyer to defend the strike level.
