I'm a rookie trader, been active for a year now, mostly as a hobby. Sticking mostly to long term trend trading and such, but considering breaking into day trading. I've been reading about scalping. From what I've read, it works as follows; 1) Select a fairly liquid, inactive market 2) Enter a limit order at or slightly above the bid price 3) Sell position at ask price. Is that the general idea and how much more is there to it? If I were to start trading tomorrow, how badly would I be blown out of the water or ripped apart by market markers?
