Why can't Tongda's MACD deviation indicator be used in Wenhua Finance? Please change it.

DIFELSEF := EMA (closing, 12)-EMA (closing, 26);

DEA:= EMA(DIFELSEF，9)；

a 1:= bars last(REF(CROSS(DIFELSEF，DEA)， 1))；

B 1:=REF(CLOSE, A 1+ 1) > Close & amp& ampREF(DIFELSEF, a1+1) <; Diffelsef & amp& ampCROSS(DIFELSEF, DEA);

c 1:= bars last(REF(CROSS(DEA，DIFELSEF)， 1))；

D 1:=REF(CLOSE，c 1+ 1)& lt； Close & amp& ampREF(DIFELSEF, C 1+ 1) > difelsef & amp& ampCROSS(DEA, difelsef);

DRAWTEXT(B 1, LOW-5,' M- bottom deviation');

PLAYSOUND(B 1，' F ')；

DRAWTEXT(D 1, height +6,' m top deviation');

PLAYSOUND(D 1，' E ')；

The above indicators' e' and' f' with voice prompts can be modified according to your own preferences.
