What is equity curve?
Your cumulative realized P&L plotted as one continuous line over time.
Definition
Your cumulative realized P&L plotted as one continuous line over time.
Equity curve, explained
Each closed trade adds (or subtracts) from the line. A smooth, rising curve says your edge is consistent. A jagged curve with deep dips says your sizing or stops need work — even if the end result is positive.
Where equity curve shows up in a journal
A trading journal is where this stops being a definition and becomes your own number. sizeforzero computes it from the trades you import or log, alongside the rest of your analytics vocabulary, and every figure in the app carries an (i) that explains it in the same plain English you just read.
