Round numbers (key levels) used as one of the reasons for profit-taking or entry points in FX trading. MT5 does not have a default feature to draw these lines. This time, I have created a convenient indicator that automatically draws round numbers on the chart, and I am releasing it. It can be set to draw lines for half numbers and other levels, so if you want to try using it, please do so. ラウンドナンバー（キリ番）にラインを自動表示

Inputs

Since it can be slightly customized, please modify it to suit your ease of use. インプット

[Gold notation]Depending on your securities company, the notation for GOLD may differ, so please enter the symbol name displayed at the top left of the chart. If you are using something other than ⅛ Gold, the default setting is fine. ゴールド表記

How to check the symbol nameWhen you open the chart, the symbol name is displayed at the top left. シンボル名の確認はチャートの左上を見よう

[Display Settings][Specified Time Frame](Implemented on September 19, 2025)

If you set the display setting to "true", then only the lower time frames than the selected time frame will display the lines & buttons on lower time frames, and hidden on higher time frames. For example, if 1-hour is selected, lines will display on time frames below 1 hour (excluding 1-hour), and both lines and buttons will be hidden on time frames of 1 hour or more (including 1-hour). ラウンドナンバーラインの表示時間を選択することができます。 [Number of lines]The number of round number lines displayed on the chart. You can display one line for the nearest level, with additional lines above and below by the specified number of levels. 表示させるラウンドナンバーのラインの数を設定できます。 [Interval (Pips)]Automatically draws lines every 100 Pips. If you want to draw lines for half numbers, set to 50, and lines will be drawn every 50 Pips. ラインを引くPips数を指定 [Line Thickness]You can choose the line thickness from five levels. ラインの太さを設定可能 [Color]You can select your preferred color from the color palette for the lines. ラインの色はカラーパレットより選択可能 [Hide Price Labels]Labels are displayed on the right side of the chart where lines are drawn. If you do not need these labels, set to true to hide them. By default, it is false. falseの場合はラベルが表示されます Setting to true will remove the labels. trueにするとラベルが消える

Button Settings

When you set the indicator, a button will appear on the chart. ボタンが表示されます

If you do not need the button, set to false to hide it. ボタンが必要ない場合はfalseにするとボタンが消えます

The button can be placed anywhere in the four corners of the chart, and its position can be fine-tuned. ボタンの詳細設定をすることができます

Sometimes, you might want to temporarily hide the lines... In such cases, you can simply click the button on the chart to toggle the display of the lines. ボタンをポチっと押すと

Pressing the button will hide the lines; pressing again will show them. ラインが消えます

Since it is designed to keep the basic display active, if you switch time frames or currency pairs while it is off, the button will turn on and the lines will be displayed. If it becomes inconvenient, I will modify it again.

Color

Colors are changed via input, so this section is not used. カラー

Display Selection

Please set here if there are time frames you do not want to display. 表示選択

That concludes the explanation regarding this indicator.
