You can set up and activate contingent orders at any time (including outside of standard market hours), however, because contingent orders require updated Level I quote information to function, they will not initialize until the next trading session.
Contingent Orders become inactive at the end of the standard session (4:00 p.m. ET), but they remain in the Order Status tab pending further action such as editing, activation, cancellation (deactivation) or removal.
Contingent orders based on indices should only be set up using the variables Trade Price, Change from Open, and Change from Close variables. Although you can create conditional orders that use indices using other variables such as Bid or Ask, these alerts will never fire because that data does not exist for indices.
Conditional orders on symbols with wide spreads may not fire if the spread is too wide.
Contingent orders automatically cancel if triggered within 10 seconds of being set.
Brackets, Conditional Orders, and Alerts created in the StreetSmart platforms can only be viewed and managed from the StreetSmart family of applications and are not currently available from Schwab.com or other Schwab applications.
When placing a contingent order where you are trading a securities in your account, if the tradable quantity of your position is less than the order quantity, the order will be sent for the lesser amount (as opposed to rejecting the order due to insufficient shares available to trade).
Contingent orders which have been inactive for 4 months will be automatically removed from the system.
