Forgive my tech ignorance, but as far as the amount of usage involved for a full-time trader, would it matter how many streaming charts (or other data) you had coming in all day?
If you buy when the market is going up, you are indeed "guessing about 'wot next'" - you're guessing it will continue to go up.
The market is always going up AND down... this is what makes a market. Whether you get good at "guessing" continuations or reversals, as long as you have signals...
If it's money above and beyond what your original stake was then it was money you won from "the house" at some point, meaning it was ONCE the house's money. But "Once the house's money" is kinda of long to say, so .... " house money". :cool:
