Show my real curveHow compounding works
Ending balance = starting balance × (1 + return per period)^number of periods. Gains enlarge the base for the next period, so a repeatable edge produces a curve rather than a straight line.
The rate matters more than the fantasy
Ten percent a month compounds to about 214% a year. A repeatable 1% to 3% monthly pace already compounds to roughly 13% to 43% annually. Compare assumptions instead of treating the smoothest curve as a promise.
Losing streaks change the path
A positive average trade can still compound below its naive arithmetic return because losses shrink the base before the next gain. The statistics mode estimates both the naive and geometric paths so the gap stays visible.
