What is the difference between P/L Open and Unrealised P&L?

Hi Seedly community, new investor here. Just bought my first stock yesterday! Wondering if there's a difference between the two terms? Thank you very much!

Profit/Loss (P/L) Open: P/L Open is the amount of money made or lost on your position since the inception of the trade.

Unrealised Profit & Loss (P&L) is the current profit or loss on an open position. The unrealised P&L is a reflection of what profit or loss could be realised if the position were closed at that time.
