What is Candle_OHLC_click?
Candle_OHLC_click lets you select a candle and draw lines from its open, high, low, close, high-low midpoint, and candle-body midpoint. The C key triggers it by default, and the levels of the candle you pick are drawn as horizontal objects on the chart.
The Inputs dialog separates the level-visibility controls from the style controls. Each price level can therefore be shown or hidden and assigned its own color, while text, width, and rightward extension remain configurable.
How to use Candle_OHLC_click
Press the configured hotkey, click the candle whose levels you want to mark, then read the enabled OHLC and midpoint lines. An existing line can also be selected to move or delete it.
Hotkey (1 second) changes the key, Text show and the font inputs change labels, and the Levels show group changes which candle prices are drawn. The Styles group changes each level’s color, line style, width, and extension to the right.
Where it helps
Open, high, low, close, and two midpoint levels can be displayed.
A line that has already been drawn can be selected to move or remove it.
Visibility and color controls are provided for each level.
