Higher/Lower

Choose a target price (Barrier) and predict if the market price will be higher or lower than the target at the end of the contract.

If you select "Higher", you win the Payout if the Exit spot is strictly higher than the Barrier.

If you select "Lower", you win the Payout if the Exit spotis strictly lower than the Barrier.

If the Exit spot is equal to the Barrier, you don't win the Payout.
