The Sold-the-Top Calculator: What Perfect Timing Would Have Paid
Published 10 September 2026 · Numbers update daily · 3 minute read
The short answer: the top is only obvious in screenshots. These cards show the gap between perfect timing and what holding actually paid, and the mirror image, what buying the worst day cost.
How the calculator defines the top
The window starts on your purchase date and ends today. The top is the highest daily close inside that window. Selling there gives the peak value. Buying there, with the same dollars, gives the worst-case entry. Both use the same daily series, so the two numbers are directly comparable.
What the gap tells you
Missed-versus-top is a regret number, not a strategy. It is large for every volatile asset because volatility is what makes tops tall. The more useful reading is the drawdown after the top, which the tool shows as max drawdown, because that is what a holder actually lived through.
