Largest jump between one hourly close and the next open across a break in the series (last 40 bars, 2 breaks): 80 JPY, 0.5× ATR. A stop inside a jump like that fills at the open, not at its own price.
The modeled levels are an estimate from OHLCV of where other traders' stops may be concentrated — not broker orders. In Ampeld's own no-look-ahead test, price reached them no more often than a random level at the same distance, so they are not targets or predictions. Use them to check whether your own stop sits with the crowd. How we tested this
The calculation
How Nikkei 225 position sizing works
Position size = (balance × risk %) ÷ stop distance per index unit, with JPY converted into the account currency.
Estimated margin = notional ÷ leverage. Leverage changes the margin reserved, not the loss between entry and stop.
Risk/reward = target distance ÷ stop distance. It says nothing about how likely either price is.
Worked example — the calculator's opening plan. A USD 10,000 account risking 1% (USD 100) with the stop 164.29 from a 66,615.00 entry (1× ATR) gives 96.07 index units: about USD 40,548 notional, 4.1× the account, and USD 2,027 margin at 1:20. That is arithmetic, not a suggested stop.
The planned loss is a price-distance estimate, not a maximum: spread, slippage, commissions, financing, gaps and close-out rules can make it larger. Everything you enter stays in your browser and is not sent to Ampeld or to analytics.
Sizing Nikkei 225
What to check before you trust the number
- Nikkei 225 is quoted in JPY points. The reference price and levels here come from front-month CME futures, which sit slightly away from the cash index and from CFD quotes. You trade it through futures, CFDs or ETFs, and each assigns its own cash value to a one-point move. The default is one index unit per contract; replace it with your product's multiplier.
- JP225, JPN225 and NI225 are broker names for the Nikkei 225. It is quoted in JPY, so P/L is converted into your account currency at a delayed reference rate you can overwrite.
- The hourly futures series runs nearly 24 hours on weekdays, with a short daily pause and a weekend break. Price can open away from Friday's close.

Questions
Nikkei 225 sizing questions
What is one point of Nikkei 225 worth?
The index itself has no fixed value per point — the product you trade sets it. Futures, CFDs and spread bets on Nikkei 225 each use their own multiplier, so enter yours under Broker settings; the default is one index unit.
Why does the JP225 result depend on my account currency?
The Nikkei 225 is quoted in JPY, so P/L is in yen. The calculator converts it into the account currency at a delayed reference rate you can overwrite.
