hello, I am currently searching for a good broker ,who will allow me to place pre-market trade set-ups such as ,eg., if stock reaches (intra-day) a 10% profit level, then trigger a 4% trailing stop incase of sudden move down or, another example, if stock by 3:15 pm does not trigger any set orders , then sell at current price , (I currently use optionsxpress which only allows basic stops and not much else). Any ideas?
