Workspace persistence API for KLineCharts Pro

[sjsalimi]

Hello KLineCharts team,

We are evaluating KLineCharts Pro for a trading analytics platform where workspace persistence is a core requirement.

Based on the official KLineCharts Pro API documentation and runtime inspection of the Pro instance, we can reliably access and persist:

• symbol
• period
• timezone
• theme
• styles
• locale

However, we could not find public Pro APIs for:

• reading the current runtime indicators after users add/remove indicators from the Pro UI
• reading or exporting drawings/overlays created from the drawing toolbar
• importing/restoring drawings/overlays
• accessing the underlying KLineCharts core chart instance in a stable/public way
• exporting/importing a complete chart workspace

At runtime, the Pro instance exposes methods such as:

• getSymbol / setSymbol
• getPeriod / setPeriod
• getTimezone / setTimezone
• getTheme / setTheme
• getStyles / setStyles
• getLocale / setLocale

But we do not see public methods such as:

• getIndicators
• createIndicator
• removeIndicator
• getOverlays
• createOverlay
• removeOverlay
• exportWorkspace
• importWorkspace

Our questions are:

1. Does KLineCharts Pro currently provide an official way to access the underlying core chart instance?
2. Is there an official API for reading/restoring runtime indicators and drawings created through the Pro UI?
3. Is workspace export/import supported or planned?
4. For advanced use cases requiring persistent drawings, strategy zones, annotations, and AI-readable chart state, do you recommend using KLineCharts Core directly instead of Pro?

We want to avoid relying on private/internal properties such as _chartApi, unless that is an officially supported approach.

Thank you for your work on KLineCharts.

As a user, I built a tool for my own use, and I think everything is there for me to stop using TradingView, a lot of it is custom overlays which is how for example I want to create an arrow (not standard in API) for a user to click a button and draw one (which is essentially a shape of a line with a triangle at the tip). And that arrow can absolutely be saved such that it can be recalled. And trend lines are pretty standard, it's all in the API doc. Moving averages are easy while I could do MCDX indicators and thats hard. I am not paying anything Pro, all custom JS.
