>I used to always put in stop loss orders.
>It was just part of the trade.
>I would enter a trade and then immediately put in a stop loss order.
>It was as second nature to me as slipping my little pinkies into soft slippers before touching the hard, cold, tile on the bathroom floor in the morning.
>But I was getting stopped a lot so started to pay more attention.
>I would watch my stop loss order being filled then, in pure and utter amazement, watch the price reverse course and take on the characteristics of the Dukes of Hazzard running from Sheriff Rosco P. Coltrane.
>I was immobilized with a feeling of a bride left at the altar. I was just as angry as the aforementioned bride would have been so I set out to answer the question:
What the heck was happening?
>Here is Bruce Robinson’s response when I posed the question to him (Bruce is also a personal friend of Howard Bandy’s ).
>“Early on, I did quite a bit of testing with stop-loss orders (and trailing stops as well). My conclusion was that they hurt the results of the vast majority (almost all) trading systems, or resulted in over-fitting of stop parameters. So, I decided not to use them, and not to incorporate the option into systems. I later confirmed this with others. Howard (Bandy), for example, also says that they almost always hurt performance.
>Please note the above statement is talking about perfectly executed stops where:
>-other participants such as brokerages or ECN’s did not have knowledge of stop points
>-stops were triggered by executed order prices
>In practice, stops perform even worse because the above two conditions do not hold true.”
>I’m sure I’m getting some head nods in agreement, however, I’m just as sure there are more out there ready to tar and feather me who still believe stop losses are as necessary as the air you breathe. If you are in the latter category, please read on.
