多週期選股

請問小幫手 我要選 跨頻 D / W / M  " rsi "  今天 > 昨天 > 前天 > 大前天,可是一直錯誤找不出原因,請協助指導更正,謝謝

input:length1(6,"rsi天期"),length2(12,"rsi天期");

variable: rsi_(0);

value1 = xf_RSI("D",Close,6);       

value2 = xf_RSI("W",Close,6);      

value3 = xf_RSI("M",Close,6); 

if  value1 > value1[1] and value1 > value1[2] and value1 > value1[3] 

and value2 > value2[1] and value2 > value2[2] and value2 > value2[3] 

and value3 > value3[1] and value3 > value3[2] and value3 > value3[3] 

then ret = 1;

outputfield1(value1,"RSI");

outputfield2(value2,"RSI2");

outputfield3(value3,"RSI3");
