No, in fact it works on a different way.
I risk max 0.3% of my equity at each trade ( 3 usd out from each 1000 usd ).
I use no stop or limit, and not because of the nfa rules, because my account is in england i can use both of them, but i dont do it because i dont care if i have some pips against me while my trend is still lined into my direction.
If the trend change then i can 1) close that position with whatever a profit of loss it can have, 2) start my plan b or c - in such case -.
Basically i am trend chaser, i have had positions loosing 300 or more pips but since my trend hasnt changed i stick to it and eventually profit from that position.
Anyway at a previous post i said i closed a couple of positions loosing about 600 pips three weeks ago, with my rule (0.3%) i lost only 18% of my account but that same week i had a lot of winning positions so i closed the week winning 620 pips, if my invstment were higher than what i do i could be margin called.
Anyway, its not often that i have such situations, for example last week at some time i had won about 600 pips but i had some loosing positions with a total of -780 pips my net effect was -180 pips ( 5.4% of my equity - a small drawdown -), that was wednesday, i reviewed all graphs and decided there was no need to implment plan b so i sticked, thursday evening i had won 1,060 pips without open positions, it was friday when i decided to enter into a couple of positions, the first one was closed with 12 pips (very small but the trendline was starting to show signs that it would change) and the other one is actually loosing 98 pips but my trend is basically the same so i stick to it.
