3. Market order protection

Market order protection is a protection applied to market orders to ensure that these are not executed at undesired prices. The market order protection will ensure that the trade price for market orders shall be within a certain price band (depending on the market order protection value). The market order protection value (which will be supplied by the member, when the market order is entered) will be an absolute money value, as appropriate. For a market buy order it will be relative to the BBO offer price and for a market sell order it would be relative to the BBO bid price.

4. Drip Feed Order

A Drip Feed Order is an order in which the member has the option to specify a replenish quantity along with the total order quantity.

In case of Buy order the limit price will be equal to Order Rate plus Protection Value and in case of Sell order the limit price will be equal to Order Rate less Protection Value.

A stop loss order can be modified or deleted until it is not converted to a limit order.
