Order types which provide privacy by either hiding the entire order quantity (i.e. hidden orders) or allowing the display of only a specified portion of the submitted order quantity (i.e. iceberg/reserves) are not supported for all product types and venues.
Examples of venues for which hidden and iceberg/reserve stock orders are not supported in the Pink Sheet and OTCBB. Hidden or iceberg/reserve orders submitted to these venues will be rejected and will generate the following message "Order quantity must be fully displayed for the instrument". Orders receiving this rejection message will require the removal of any hidden or display size attribute prior re-submission.
Additional information regarding product types and venues for which these order types are supported is available through the links below:
