原理解析：
输出OBV:SUM(IF(收盘价>1日前的收盘价,成交量,IF(收盘价<1日前的收盘价,-成交量,0)),0)/1000000
A1赋值:2日前的OBV=2*2+1日内OBV最高值
B1赋值:A1的2过滤

C1赋值:BACKSET(B1,2+1)

D1赋值:C1的2过滤
{高}
A2赋值:2日前的OBV=2*2+1日内OBV最低值

B2赋值:A2的2过滤
C2赋值:BACKSET(B2,2+1)
D2赋值:C2的2过滤
{低}
H1赋值:(D1 AND NOT(D2)) OR BARSTATUS=2 OR C的有效数据周期数=1
L1赋值:(D2 AND NOT(D1))

H2赋值:D1 AND NOT(D2)

X1赋值:REF(上次H1距今天数,1)+1
如果L1返回L否则返回10000
G1赋值:F1>1日前的F1

I1赋值:BACKSET(G1,2)
LD赋值:I1>1日前的I1
{过滤后低点}
L2赋值:LD OR BARSTATUS=2 OR C的有效数据周期数=1
X2赋值:REF(上次L2距今天数,1)+1
如果H2返回H否则返回0
G2赋值:F2>1日前的F2

I2赋值:BACKSET(G2,2)
HD赋值:I2>1日前的I2
{过滤后高点}
R1赋值:BACKSET(BARSTATUS=2,上次HD距今天数+1)

S1赋值:R1>1日前的R1
{前一高}
R2赋值:BACKSET(S1,REF(上次HD距今天数,1)+2)

S2赋值:R2>1日前的R2
{前二高}
R3赋值:BACKSET(S2,REF(上次HD距今天数,1)+2)

S3赋值:R3>1日前的R3
{前三高}
T1赋值:BACKSET(BARSTATUS=2,上次LD距今天数+1)

U1赋值:T1>1日前的T1
{前一低}
T2赋值:BACKSET(U1,REF(上次LD距今天数,1)+2)

U2赋值:T2>1日前的T2
{前二低}
T3赋值:BACKSET(U2,REF(上次LD距今天数,1)+2)

U3赋值:T3>1日前的T3
输出{前三低}
