The parameters of such pre-execution checks and filters may include but are not limited to:
(a) dollar limit to control the gross buy and sell value and/or net buy/sell value. This limit may be applied to an individual customer, a Trading Representative, a group of related accounts or a proprietary account carried on the books of the Trading Member;
(b) security limit to control the dollar/quantity exposure to each security. This limit may be used to control concentration risk for each customer and for the Trading Member's accounts as a whole on a per-security basis;
(c) dollar/quantity limit and price limit for each order. This allows for the detection of errors in inputting orders. For example, if a customer or Trading Representative were to enter an unusually large sized order or an order at a price that is far from the prevailing price, they could be alerted for confirmation of the order before it is accepted by the system; and
(d) controls to restrict customers to selected markets, order types and securities.
