Macd bergamot takes the stock formula of Tongda letter and makes two stock selection formulas. Come on, turning red is stock selection.

{Turn red and choose stocks}

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

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

DEA:=EMA(DIF，9)；

MACD:= 2 *(DIF-DEA)；

FH 1:=REF(MACD， 1)& lt； REF(MACD, 2) and REF(MACD, 2) < REF(MACD, 3) and REF(MACD, 3) < References (MACD, 4);

FH2:=MACD >=0 and count (MACD >; REF(MACD， 1)， 1)= 1；

FH3:=FH 1 and FH2 and EMA(C, 13)>REF(EMA(C, 13),1);

FH4:=FH 1 and FH2 and ABS ((dif-DEA)/c) < 0.0 18;

FH5:=FH 1 and FH2 and MACD <; 0. 10;

Turn red: (FH3 or FH4 or FH5);

{Come on, stock selection}

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

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

DEA:=EMA(DIF，9)；

Come on: Cross (DIF, DEA) and DIF>；; 0;
