若程式中有使用到週KD，常發生當天有測到某些股票，到當週週六回測試該股票確不會被測到

我的程式碼如下：

input: Length_D(9, "日KD期間"); input: Length_W(1, "周KD期間"); variable:rsv_d(0),kk_d(0),dd_d(0); variable:rsv_w(0),kk_w(0),dd_w(0); stochastic(Length_D, 3, 3, rsv_d, kk_d, dd_d); xf_stochastic("W", Length_W, 3, 3, rsv_w, kk_w, dd_w); condition1 = kk_d[2] crosses above dd_d[2]; // 日KD crosses over condition2 = kk_d[1] > dd_d[1]; condition3 = kk_d > dd_d; condition4 = close>20; condition5 = close<100; condition6 = average(volume[1], 2) >= 2000; condition7 = kk_d[1] > 30; condition8 = xf_getvalue("W", kk_w, 1) > 40; condition9 = kk_w[1]>dd_w[1]*1.05 ; condition10 = kk_w>dd_w*1.2 ; ret = condition1 and condition2 and condition3 and condition4 and condition5 and condition6 and condition7 and condition8 and condition9 and condition10;
