highPrice = high
DRAWTEXT("High Price", barindex, highPrice) COLOURED(255, 0, 0, 255)This code snippet will display the text “High Price” at the highest price point of the current bar on the chart, colored in solid red.
Additional Information:
- Variables can be included within the text by enclosing them in pound symbols (#). For example,
DRAWTEXT("High: #highPrice#", barindex, highPrice)will display the actual high price value in the text. - The DRAWTEXT function is often used in conjunction with other graphical functions like DRAWLINE to provide a more comprehensive visual analysis tool on the chart.
This function is essential for traders who use visual aids to enhance their chart analysis, making it easier to identify and annotate key data points directly on the chart.
