【無料】RCI3本 買われすぎ売られすぎ抜け出しでサインとアラートインジ

RCI3本を使ったインジケーターです。

買われすぎラインを80　売られすぎラインを-80とし、このラインに短期線、中期線、長期戦いずれかが抜けだした時にサインが出現します。

サインに合わせてアラートを鳴らすこともできます。

RCI80OUTインジケーター

コチラがインジケーターを表示させたときの画像。

トレーディングビューの下の段にRCIを3本表示します。

短期線：S
中期線：M
長期戦：L

でサインを表示。サインはそれぞれ表示、非表示切り替えられます。

例えばこの画面のように、短期のサインだけ、中期長期だけなど細かく調整できます。

コチラはパラメータ画面。短期中期長期、買われすぎ売られすぎの数値はそれぞれ設定できます。

ただし、買われすぎ売られすぎのラインを変更したとしても、サインやアラートは±80で固定です。

コチラがスタイル画面。短期中期長期線のラインの色や太さはコチラで変更可能です。

コチラがアラート画面。

短期、中期、長期の買いサイン売りサインに合わせて設定できます。
