In answer to the poster's original question, yes, that's how it works.
Last week, trying a new system, I started with $600 (it was insane, I know from my own experience, but it worked out...this time).
By the end of the week, I was up to $1,500, which is almost 200% profit.
On the other hand, I TRIED 1 point wins and losses for two years, and lost HUNDREDS of points trying to make it work. As other people have pointed out, it all looked so easy on paper, but at least once a week, sometimes more, I hit multiple losses in a row. Scalping does not fit my personality - it requires too much discipline, especially after a string of losses - no, particularly after a string of losses - and I could never stomach jumping back in after getting my ass handed to me 3-4 (and sometimes 5) times in a row.
My new system is more of a trending system, has a set stop loss (2.25 points, moved up if the trade is working), a larger goal (2.75 at first), and, at least in theory, an open-ended gain (never held it for more than 6 points, but I've seen it, real time, go as far as 22 points on a single, beautiful trend).
In theory, my new system is scalable up to maybe 700 contracts per, but in practice, who knows? I've never gone beyond 10 contracts.
