We recently introduced 30-hour Extended Trading access for mobile users (see the Android or iOS release notes).
For your protection, this feature requires that fingerprint or PIN/Pattern security be enabled on your mobile device. If not enabled, a 20-minute inactivity grace period applies, after which you are disconnected from your trading session and logged into Read-Only mode (which can be disabled), and must perform a full login for trading access.
While we remain diligent in our efforts to keep your account protected, we understand that good security is also about striking a balance between safety and convenience. If you feel strongly that this change adds undue burden to your trading setup - we'd like to hear from you. Please vote on the
Enhancement Request available through our Features Poll.
