请帮我在下面交易系统公式里，写上K线图上面的欢迎词语（投资需谨慎，信号只是交易辅助），谢谢
 
INPUT:P(26,20,100,8);
INPUT:B2(2,0.1,10,1);
INPUT:S(12,5,40,4);
INPUT:B1(26,5,300,30);
INPUT:N2(10,1,120,12);
INPUT:N3(20,1,200,20);
INPUT:N4(60,1,200,20);
INPUT:ss(1,1,10000,1);
MA2:MA(C,N2);
MA3:MA(C,N3);
MA4:MA(C,N4);
MID := MA(CLOSE,B1);
UPPER:= MID + B2*STD(CLOSE,B1);
LOWER:= MID - B2*STD(CLOSE,B1),COLORRED;
DIFF := EMA(CLOSE,S) - EMA(CLOSE,P);
手数:=SS;
VARIABLE:VMIN = 090000;//用于隔夜高开或低开时间差
IF (ABS(O-REF(C,1))>=20*MINDIFF AND TIME>090000 AND TIME<090400) THEN VMIN := 091500;
//开多仓条件：
BOPEON1:=C>UPPER AND DIFF>0 AND C>O AND C>MA4 AND HOLDING=0 AND TIME>VMIN AND TIME<150000;
//平多仓条件：
BLIQCON:=HOLDING>0 AND CROSS(MA3,MA2);
//开空仓条件：
SOPCON1:=C<LOWER AND DIFF<0 AND C<O AND C<MA4 AND HOLDING=0 AND TIME>VMIN AND TIME<150000;
//平空仓条件：
SLIQCON:=HOLDING<0 AND CROSS(MA2,MA3);
 
BUY(BOPEON1,手数,MARKET);
SELL(BLIQCON,HOLDING,MARKET);
BUYSHORT(SOPCON1,手数,MARKET);
SELLSHORT(SLIQCON,HOLDING,MARKET);
//收盘前平仓
SELL(TIME>151000 AND HOLDING>0,HOLDING,MARKET);
SELLSHORT(TIME>151000 AND HOLDING<0,HOLDING,MARKET);

用DRAWTEXT函数即可。

我谢的语法错误，     请举个例子，颜色是红色，字体是25号，谢谢
