标题：交易系统编写求助

对于下面的交易指标公式，请帮忙改写成自动交易系统公式：

{1.“卖线（白线）”上穿“比卖线（粉线）”，买入2万元；
2.反之，“卖线（白线）”下穿“比卖线（粉线）”，全部卖出；
3.用于股票自动交易
}
ss:=max(floor(20000/close/100)*100,100);
N:=13;

M:=9;

m1:=3;

VAR1:=(CLOSE-LLV(LOW,N))/(HHV(HIGH,N)-LLV(LOW,N))*100;

VAR2:=SMA(VAR1,M1,1);

卖线: SMA(VAR2,M1,1);

VAR3:=(HHV(HIGH,M)-CLOSE)/(HHV(HIGH,M)-LLV(LOW,M))*100;

VAR4:=SMA(VAR3,M1,1);

VAR5:=SMA(VAR4,M1,1);

买入线: SMA(VAR5,M1,1);

必卖线: SMA(卖线,M1,1);

高压线: 85;

触底线: 9;

DRAWTEXT(买入线>76.5 AND CROSS(卖线,必卖线),必卖线*1.15,'进');

DRAWTEXT(买入线>56 AND 买入线<=76 AND CROSS(卖线,必卖线),卖线,'留意');

DRAWTEXT(买入线<45 AND 卖线>78 AND 必卖线>78 AND CROSS(必卖线,卖线),必卖线,'跑'),COLORGREEN ;

DRAWTEXT(CROSS(买入线,78.5),买入线,'关注'),COLORRED ;

DRAWTEXT(CROSS(买入线,85),买入线,'重点关注'),COLORWHITE ;
if cross(卖线,必卖线) then buy(holding=0,ss,market);
if cross(必卖线,卖线) then sell(1,ss,market);

买入、卖出都在第二天操作，怎么改？
