explain(1,'均線金叉關鍵低點=',numtostr(金叉關鍵低點,2)),colorffff;

下面兩句應該如何寫才對？

explain(1,'均線金叉關鍵高點=',numtostr(金叉關鍵高點,2)),COLORMAGENTA;
explain(1,'均線金叉關鍵低點=',numtostr(金叉關鍵低點,2)),colorffff;

explain(1,'均線金叉關鍵高點='&numtostr(金叉關鍵高點,2)),COLORMAGENTA;
explain(1,'均線金叉關鍵低點='&numtostr(金叉關鍵低點,2)),color00ff;

請仔細看看explain函數的使用說明
