MQL では PNG 画像が使えないので、透過画像であれば簡単にできる十字カーソルのような表現が難しいですよね。
かなりの力技ですが、BMP 画像を使って、透過画像を使ったかのように標準の十字カーソルとまったく同じ表現ができたので共有します。体感的な負荷も特に上がりません。
必要な BMP 画像は十字線の実体上下左右４枚と１ピクセル線用画像縦横１枚ずつの６枚ですが、１ピクセル線用画像を縦横１枚ずつコピーして上下左右の名前を付けて計８枚にしてしまった方が直感的です。十字線の実体は色とか塗ったらカワイくなりそうですね。
構造は以下の通り１ピクセル線用画像４枚の上にレイヤー的に十字線実体画像４枚を重ねて置いているだけです。この構造を守ったままマウスカーソルに追従させます。
使うオブジェクトは OBJ_BITMAP_LABEL です。OBJPROP_ANCHOR を表示位置と逆側に設定して、それぞれをピクセル単位で微調整したら完成です。

RECTANGLE_LABEL での実装
RECTANGLE_LABEL でも実装できます。画像を作らなくて済むのでその分楽ですが、部品が増えてサイズ指定、色指定、ボーダー指定が必要になるのでコードが長くなります。でも簡単に色を変えられますね。RECTANGLE_LABEL は ANCHOR が効いているのかいないのかよく分からないので未設定です。MQL4 では感じないですが MQL5 では BITMAP_LABEL の方が軽快です。
