TWS Messages - Your account has been restricted to closing orders only

Account holders receiving the following message 'Your account has been restricted to placing closing orders only' are limited to placing orders which serve to close or reduce existing positions (i.e., sell orders which close out or reduce existing long positions or buy orders which which close out or reduce existing short positions).  The basis for this restriction varies and often involves pending documentation, compliance and/or risk issues. Regardless of its basis, the restriction affords account holders the ability to manage and reduce the market exposure of their positions while in effect.  Questions regarding this restriction should be addressed to Customer Service (see contact information link below).

TWS Messages - Order quantity must be fully displayed for this instrument

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 are 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 this instrument". Orders receiving this rejection message will require the removal of any hidden or display size attribute prior to resubmission.

Additional information regarding product types and venues for which these order types are supported is available through the links below:
