I'd like to draw text objects either attached to a bar's high or low, or anchored an arbitrary distance in pixels from a (time, price) coordinate. Is there any way to do that?

Thanks.

You can do it by using ITextChartObject interface. https://www.dukascopy.com/wiki/en/development/strategy-api/chart-objects/chart-object-catalog#text

Thanks for your reply. I see on that page and in the javadocs where it discusses drawing in the time/price coordinate system, but it's unclear to me how I could either use those APIs to attach text to a bar (so that it would always show right above or right below the bar, move with the bar as it grows upwards and downwards, and be a fixed pixel distance from the bar regardless of zoom settings) or how I could draw a label at a fixed pixel offset from a time/price coordinate (for example, draw 5 pixels above and 2 pixels left of price = 1.1, time = Wednesday at midnight).

If either those things can be done, could you point me closer toward the documentation for doing things like that?

Thanks again.
