Net return
Separate spot movement, spread, commission, swap, and gap slippage. This makes the strategy portable across brokers with different financing.
Editorially reviewed 24 August 2026
Carry and price are one return path
DESK 24USDJPY swing trades can be affected by interest-rate differentials, rollover conventions, policy repricing, and discontinuous moves. A pip-only journal is incomplete when positions remain open for days. Record gross price return, financing, costs, and net realized R separately.
Use policy and intervention tags only from information available at the time. Test the same price rule through ordinary and tagged windows, stress gap and slippage assumptions, and report how the worst sequence interacts with any account-level loss limit.
Separate spot movement, spread, commission, swap, and gap slippage. This makes the strategy portable across brokers with different financing.
Save the contemporaneous calendar or policy source used for each tag. Later explanations can leak information into historical decisions.
Simulate trade order chronologically and inspect losing streaks, drawdown duration, and clustered exposure around policy windows.
For multi-day yen trades, financing and discontinuities belong in the result—not in a footnote.
Interest-rate differentials and policy expectations can be used only through a predeclared variable whose historical release and revision timing is known. A later macro explanation cannot validate an earlier entry.
Swing holds expose the account to financing, weekends, and central-bank surprises. Model the intended quote and swap conventions, and express outcomes in account risk as well as pips.
| Measurement | How to define it | Why it matters |
|---|---|---|
| Macro timestamp | Source value, release time, revision and decision lag | Prevents future or revised information leakage |
| Yen risk | Pip value, quote precision, stop distance, account conversion | Keeps size consistent across prices |
| Carry and gap cost | Financing, weekends, event slippage and spread | Captures multi-day execution economics |
| Regime stability | Results by rate, trend, volatility, and calendar segment | Shows whether one carry phase drives performance |
Historical rate and intervention episodes are few and dependent. Report them as case studies inside a broader sample, not as a guarantee that the next episode will behave similarly.
