The fnDrawText is used to draw a label containing text on a price chart. It is positioned by price and candle.
After the fnDrawText function has been added to a Drawing, it is configured by clicking the (+) button along the bottom of the Element.
The Function Configuration window allows you to select values for each parameter.
Each Chart Object function offers a number of parameters on the Configuration Tab, and also a number of parameters on the Advanced Tab.
- Parameters on the Configuration Tab should be inspected and set each time the function is added to a drawing.
- Parameters on the Advanced Tab usually do not need to be changed from their default values.
