La tua entrata media è il tuo vero pareggio
Knowing the weighted average tells you exactly where price must return for you to be even. Plan adds with the calcolatore della riduzione della media ed esce con il DCA exit calculator.
Il tuo ingresso reale dopo più acquisti
Acquista 1 ETH a $ 3.000 e 2 ETH a $ 2.400 e l'ingresso della tua posizione non sarà $ 2.700: è la media ponderata: (1×3000 + 2×2400) ÷ 3 = $2.600. La ponderazione in base alle dimensioni è il trucco, e osservare la cosa va storto non appena gli acquisti sono disuguali.
Why precision matters: your break-even, your PnL, and your stop distances all key off this number. A trader who thinks his average is $2,700 when it's $2,600 sets his break-even stop $100 too high and exits winners as if they were break-evens. Every DCA ladder, every scale-in, every "adding to the dip" needs the recomputed average after each fill.
The psychological trap it exposes: averaging down always looks better on the average-entry number — each buy pulls it closer to the current price. The average improving is not the trade improving. The position is bigger, the total at risk is larger, and the coin still has to actually turn around.
