如何固定

請問各位大大:
例如:
X:=MA(C,5);
那如果跟前一日比較,該怎麼寫才不會出現連續從第一跟K線開始比?
謝謝

類似

X:MA(C,5);
RX:ref(X,1);
RX2:ref(X,2);
//和昨日相比
drawtext(islastbar AND X>RX,X,'今日五日均線大於昨日'),align2;//顯示位置可自行調整
drawtext(islastbar AND X=RX,X-50,'今日五日均線等於昨日'),align2;
drawtext(islastbar AND X<RX,X-100,'今日五日均線小於昨日'),align2;
//和前天相比
drawtext(islastbar AND X>RX2,X-150,'今日五日均線大於前日'),align2;
drawtext(islastbar AND X=RX2,X-200,'今日五日均線等於前日'),align2;
drawtext(islastbar AND X<RX2,X-250,'今日五日均線小於前日'),align2;
