Why Your Futures Stop Order May Not Guarantee an Exit
Many futures traders assume that once a stop order is triggered, it automatically becomes a market order and guarantees they’ll exit their position.
Did you know that’s not always the case?
On the CME Group’s futures exchange, electronic stop orders are implemented using Stop with Protection. If your stop order cannot be completely filled within the exchange’s predefined protection range, the remaining quantity becomes a working limit order at the protection range price – not a market order. If the market continues moving away from that price, your position may remain open, leaving you exposed to additional losses.
What Does Stop with Protection Order Mean?
CME Group’s Definition: Electronic stop orders are implemented using a “Stop with Protection” approach. Unlike a conventional Stop order, where customers are at risk of having their orders filled at extreme prices, Stop with Protection orders are filled within a predefined range of prices (the protected range). A Stop with Protection order is triggered when the designated price is traded on the market. The order then enters the order book as a Limit order with the limit price equal to the trigger price, plus or minus the pre-defined protected range. The protected range is typically the trigger price, plus or minus 50 percent of the No Bust range for that product. The order is executed at all price levels between the trigger and limit price. If the order is not completely filled, the remaining quantity rests in the market at the limit price. A buy Stop order must have a trigger price greater than the last traded price for the instrument. A sell Stop order must have a trigger price lower than the last traded price.
Let’s look at an example using the popular E-mini S&P 500 (ES) Futures contract
Suppose you are long one ES futures contract with a sell stop at 6000.00. The current CME Protection Point for ES is 5.00 points. This means the CME futures exchange will attempt to execute the order between 6000.00 and 5995.00. If it cannot be completely filled, the remaining quantity becomes a working sell limit order at 5995.00.
The following infographic illustrates exactly how a CME Stop with Protection order works. It also includes current Protection Point values for several popular CME futures contracts.
