 Recently I started trading and to calculate position size I used spreadsheet to manage. But for my ease, thought of build as desktop app so that I can pin the window on top while calulcating the position size. Actually I want to build a trading journal with the tools required, but being the scope is huge, I'm diving the scope into smaller achieveable chunks.
