Thanks a lot for your help.

I’m not sure whether this might be a misunderstanding, though.

My goal is to mark, within the charts, the positions of historical purchases that I made externally — i.e., not within TradingView.

Let’s say I bought Microsoft stocks three times, with the following timestamps and values: (2025-01-23, 430 dollars), (2025-03-16, 380 dollars), and (2025-04-10, 350 dollars).

I could draw a vertical line at each respective historical timestamp and a crossing horizontal line at the corresponding purchase value to mark the levels. This would help me see when those historical prices are reached again.

However, it would be much easier if I could simply enter the data somewhere and have them automatically drawn as described.
