FIFO stock management

[Anonymous]

Hello, everyone! Hope you all are doing ok. 🙂
So I'm new to Power BI and DAX and I was hoping someone can help me with this issue.
Imagine that I have a market that sells oranges. I would like to manage the stock according to a FIFO process.
So, first I sell all the oranges I have in stock until I run out of it, then I make a purchase and make all the sells until I reach 0 again.
I made an example table with data that can make you better understand my problem.


On the example, I associated an index to each buy and sell so you can understand better the goal. I need to accomplish this on a Power BI report.
Note that, even though we have dates of when the sells and the buys occur, we still need to organize the data according to FIFO.


Thanks in advance for anyone who tries to help me.

I saw that blog already and that is not the flow I need my stock to take. The goal in this specific case is to have an initial stock and make all the sells you can until you run out of stock, then you put in the first "Buy" so that you have stock for the next sales. In other words, the goal is at one point reaching an empty stock, as you can see in my table "Expected Results".
