# KD compare strategy (交易策略對照組)

This is a base and easy trading strategy for comparing my other strategy.
The strategy consider K >= 80 is strong target in the last high period,
and consider K <=20 is the weak target in the last low period.

In the strong target, the strategy may increase long at the first day when K < 50, until 2/3 max order limitation or strong target become to weak.
In the weak target, the strategy may increase short at the first day when K > 50, until 2/3 max order limitation or strong target become to strong.

there are three orders for this strategy.
when the strong become to weak, it may use the remain 1/3 to save itself, and change the direction at the next k > 50
when the weak become to weak, it may use the remain 1/3 to save itself, and change the direction at the next k < 50

read line is close transform to k = 80
white line is close transform to k = 50
green line is close transform to k = 20

rule 3, 4, clear share

2. change rule 1 and rule 2

2. add rate to enhance the effectiveness
