Ends Between/Ends Outside
A broker-specific range contract decided by whether the final price ends inside or outside two barriers.
Practical use
How to verify Ends Between/Ends Outside
Read Ends Between/Ends Outside together with Stays Between/Goes Outside, Range option, Double barrier. The comparison must preserve the exact rule, value, state, and evidence described below.
A neutral example
With spot 100, Ends between ends outside uses lower 95 and upper 105. A path touching exactly 105 tests equality, quote side, monitoring frequency, and Stays between goes outside. Ends between ends outside is distinguished here by one decisive fact: the final price alone determines inside or outside, unlike a full-path stay or breach condition.
