Ray / Extend Lines left and right on chart

[helloworldnoob]

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?

There is no built in extrapolation feature in mplfinance. Although this is the second request for it, so we can think about it.

In the meantime please try the workaround posted here and let me know if it works for you.

At any rate, if I were to implement this as a feature, I would first try the workaround, and then, if that works, I would generalize the workaround code and integrate it into the library. So please let me know if the workaround works for you.

Thanks. All the best. --Daniel

Thank you. Once I try it I will either let you know it works, or if I need help! Could be tonight or another day that I try it.
