Description

Is there a way to extend the drawn on lines so that they go further than the two points you give them?

For example, I want to draw a trend line across two points.

Now, I want to see into the future, and the past, to see how these levels can(future) / have(past) affected the price.

Is this possible?

Research direction

The issue does not name any files, tests, or entry points. Start by locating mplfinance's existing line-drawing or annotation options and determine how chart coordinates map to past and future periods. Done means documented or implemented support for extending a line beyond its two supplied points, with coverage for both directions.
