What it means
Buying a fixed amount at regular intervals regardless of price, instead of choosing a single entry.
Why it matters when you trade
DCA converts a timing decision into a process, which matters mainly because it removes the psychological trigger for the worst behaviour — buying everything at the top and nothing at the bottom. Mathematically, lump-sum investing wins more often than not when the asset trends up, so DCA is best understood as buying behavioural reliability rather than better entries.
Worked example
Four $250 buys at 100, 80, 60 and 90 average 77.5 — below the 82.5 mean price, because the fixed amount buys more units when price is low.
See it on live markets
