老师，能否将以下文华指标帮我转化成TB的呢？感谢！

MA1:MA(C,15);

TR:= MAX(MAX((HIGH-LOW),ABS(REF(CLOSE,1)-HIGH)),ABS(REF(CLOSE,1)-LOW));

ATR:=MA(TR,20);

LL1:=VALUEWHEN(CROSS(C,MA1)&&BARSLAST(CROSS(MA1,C))>=3,LLV(L,BARSLAST(CROSS(MA1,C))+1));

HH1:=VALUEWHEN(CROSS(MA1,C)&&BARSLAST(CROSS(C,MA1))>=3,HHV(H,BARSLAST(CROSS(C,MA1))+1));

LL2:=VALUEWHEN(CROSS(C,MA1)&&BARSLAST(CROSS(MA1,C))>=3,REF(LL1,1));

HH2:=VALUEWHEN(CROSS(MA1,C)&&BARSLAST(CROSS(C,MA1))>=3,REF(HH1,1));

IF(LL1>LL2+ATR OR LL1<LL2-ATR,LL1,LL2);

IF(HH1>HH2+ATR OR HH1<HH2-ATR,HH1,HH2);
