Your target, checked against the maths

Put in the number in your head. See what it asks of your account, how it compares with the long-run records, and what your own plan does over hundreds of trades. Then turn it into rules you can actually keep.

1. The number in your head

Account size ($)

Your target ($)

Every

2. Next to the long-run records

Yearly rates, on a log scale so they fit on one screen.

Long-run records. Not forecasts. Not targets. Sources: Berkshire Hathaway and S&P 500 with dividends, 1965–2024 (Berkshire 2024 shareholder letter); global equities after inflation, 2000–2024 (UBS Global Investment Returns Yearbook 2025).

3. What your plan does over many trades

Risk per trade (% of the account)

Trades per day

Winners out of every 10 trades

Average winner, in R (1R = what you risk)

Look ahead

I don't know my win rate or R yet (try a range instead) Stop for the day at −2R After a loss, double the size to win it back

These paths assume the win rate and R you typed in. Your real edge may not exist. Illustrative maths, not a forecast and not advice.

4. Your target, turned into rules

A money target can't be controlled. These can. Each one is an IF/THEN plan, written while you're calm.

My plan, not my number

MY RULES, WRITTEN CALM · METASYNCER.COM/TOOLS/TARGET-CHECK

Rules on paper still depend on you after two losses. Metasyncer checks every order you place in it against rules like these, before it reaches your broker. Closing is never blocked.
