文华源码帮忙翻译一下　[文华财经]

改写如下：

todayVolatility: = STDP(CLOSE,30);
yesterDayVolatility: = STDP(REF(CLOSE,1),30);
deltaVolatility: = (todayVolatility - yesterDayVolatility)/todayVolatility;
LD : 20 * (1 + deltaVolatility);
LDZ: =IFELSE(LD-INTPART(LD)>0.5,CEILING(LD),FLOOR(LD));
LDX:=IFELSE(LDZ>60,60,IFELSE(LDZ<20,20,LDZ));
MidLine := MA(CLOSE,LDX);
Band: = STD(CLOSE,LDX);
upBand: = MidLine + 2 * Band;
dnBand: = MidLine - 2* Band;
buyPoint: =HHV(REF(HIGH,1),LDX);
sellPoint: =LLV(REF(LOW,1),LDX);
longLiqPoint: = MA(REF(CLOSE,1),LDX);
shortLiqPoint: =MA(REF(CLOSE,1),LDX);
CLOSE>upBand&&CROSS(HIGH,buyPoint),BK;
CLOSE<dnBand&&CROSS(sellPoint,L),SK;
CROSS(longLiqPoint,L),SP;
CROSS(H,shortLiqPoint),BP;
AUTOFILTER;
