Some traders argue that brokers hunt stops and that trading without a stop loss is more profitable. Keep in mind, if your broker is a no dealing desk (read more about broker types here), your broker just passes your orders through to a liquidity provider and they do not even actively trade most of the time. Furthermore, if you are trading with a well regulated broker, they have to adhere to certain rules and cannot artificially manipulate prices. And finally, brokers earn their lion’s share through their clients’ commissions and, therefore, have an interest to keep you around or some time.
Do not make the common beginners mistake to not use stop loss orders because of one of those myths. A stop loss should be your most important tool that saves you in bad times
