源碼解析理論

輸出INPUT:INB(20,1,500,1),OUTB(10,1,500,1),RISK(2,0,10,0.1)
輸出//和風版海龜源碼VARIABLE:TIMES=0,I=0,N=0
RN賦值:1日前的真實波幅的20日指數移動平均
N賦值:如果HOLDING=0,返回RN,否則返回上個輸出值
RH賦值:1日前的最高價
RL賦值:1日前的最低價
輸出H1:INB日內RH的最高值
輸出H2:OUTB日內RH的最高值,LINEDOT
輸出L1:INB日內RL的最低值
輸出L2:OUTB日內RL的最低值,LINEDOT
輸出LOTST:ASSET*RISK*0.01/(N*2*期貨每手乘數),線寬為0
LOTS賦值:如果RISK=0,返回1,否則返回LOTST
