If the advisory service has good and practical educational content, it could be worth the subscription, but following someone else blindly usually fails. This section only applies only to the trading of liquid instruments. There are many stops at different prices in the market at any time, if your stop is located inappropriately, your stop will likely get hit. This is not the fault of the locals, it is your responsibility to place your stops appropriately. Yes, locals will try to trade in an area of clustered stops, but only if the equilibrium of buyers and sellers permits it to happen.
Locals have a privileged position, being able to profit from the spread between the bid and ask.
Too many traders think this is an unfair condition. It can be unfair if the spread is manipulated. But bear in mind that the locals assist in creating an orderly market. They provide liquidity, they take the other side of your trade. Locals take risks every day that you would not be comfortable with.
