Common comparison error
Stays-between/goes-outside is a full-path condition, not an ends-between/ends-outside test of only the final price.
GlossaryProducts & contracts
Stays Between/Goes Outside
A broker-specific contract based on whether price remains between two barriers or crosses outside them during the observation period.
Practical use
How to verify Stays Between/Goes Outside
Read Stays Between/Goes Outside together with Ends Between/Ends Outside, Asian Up/Asian Down, Higher/Lower. The comparison must preserve the exact rule, value, state, and evidence described below.
A neutral example
Lower 95 and upper 105 are monitored for five minutes. One qualifying 105.01 observation makes goes-outside succeed and stays-between fail even though price returns to 100 at expiry.

Where to verify Stays Between/Goes Outside
Use the source that governs the exact contract, account, entity, or platform state. A general definition cannot replace current broker terms.
