It is a fact that stop losses can be useful. It is also a fact that their use neccesitates an understanding of the market you are trading, and the time period you are trading, that a surpringly high number of people here seemingly dont understand. I am not suggesting I am a more successful trader, and in fact I am not a trader, but I do understand the way professionals trade.
If you are a fund for example, you may be a long term investor in oil, with a price target of 200USD; in that case, you may well have a stop a long way off the market. But your stop inconsequently not likely to be hit unless your view was totally wrong, and then it becomes a damage limitation exercise. However, if you are a market maker, you may want to try and find stops very close to the market. If you are wrong, it will be very short term, and you want a guaranteed out of your position. Most people here are not using their stops for either purpose. If you are day trading, then why have a stop 1000 points out of the money? You know you got it wrong when you are 500 points out! If you are not sure you are wrong at that point, are you buying on scale down? If not, you clearly are not that convinced off you position, and should be well and truely out of it!
Stops are a tool that can be used, but it seems people are using them for the wrong reasons quite frequently. If you are going to put on a longish term position, which you will not be monitoring, stops are indispensible in my view. If you are monitoring your positions constantly - then what purpose are you using you stop for? Do people consider for example, joining the bid when entering a new long, and hitting the bid when exiting a losing short? Or are people using stops for this?
There are a lot of people here that are ignoring what is inherently sound advice, from far more experienced people. Markets are not an easy place to make money. The fact that there is even a debate as to whether or not it is gambling says it all!!! If it was gambling, why do people with Phd's generally make more money than spreadbetters here? Why do people do degrees and years of in house training? Markets are a function of supply and demand at the end of the day. Whether a roullette wheel stops on red or black is not!!! Basics.
Anyway, that is my rant over and done with, feel free to crucify it if you want.
