how to use stops ?

[nanu]

hi
here follows what i think about and use stops. all are welcome to share their ideas.
first i tried fixed amount stop ie risking a fixed amount per trade. then i tried 2% to 5% of my risk capital. but i was not satisfied. then i decided to put the stops at the point , by crossing which my idea about the trade is negated. eg. i may enter a stock on longside at 250 , and my trend reversal point is say 205. so i will wait till 205 is broken. and i put one position long. then i trade more contracts between my stop and first target. ie i trade around my core position.
now is this ok or are there any improved methods about using stops??

pls let me know
