The use of ROC namely a problem

intraday stop loss price points are not longer broken up three minutes ,GHD Leopard Grain, and immediately stops playing .
Step one: brain of the maximum closing price by 10 yuan of three stop-loss price are:
stop-loss price as a 10 * 0.95 = 9.5
stop-loss price of 2 10 * 0.925 = 9.25
stop-loss price of 3 10 * 0.9 = 9.0
Step two : The position has been shoved down the cost of the interest rate formula :
head position cost the highest closing price / ( 1 + profit standard)
income were two standard were 25%,GHD Hair Straightener, 15%
position thought the cost of a : 10 / (1 +25 %) = 8 yuan
cost of two positions : 10 / (1 +15 %) = 8.7 yuan
Step three : position by interval:
8 yuan profit margin greater than 25 % of the interval a
8元至8 . 7元profit margins greater than 15 %,GHD MK4 Gold Straighteners, but less than 25% for the interval b
8.7 yuan to be less than 15 % of the amuse rate range of three
Step Four: Stop by the implementation of correspondence :
a corresponding stop-loss price range of a
stop-loss price range II corresponds apt the second
range of stop-loss price for three corresponding three .
