I have downloaded the TWS, and I am trying to program hot keys. I notice that the dropdown menu for the order options has changed. before, they would allow you to designate (BUY MARKET) where as now I only see (BUY), How do you program a key for a market order. It also says that you can have your market data line (default as BUY MARKET). However my asking price type says (LIMIT). How do you set your market data line default to (MARKET)? I have asked IB, however they send me a link that explains nothing. I know there has to be instructions somewhere that I don't see. Which order is safer (faster)? should I leave default to (limit) and just adjust price up and down? or use market orders? anybody here experienced enough to comment?
