Natural Gas Rollover Adjustment Calculator
Model a direction-aware cash adjustment when a futures-linked natural-gas CFD changes reference contract, using entered old and new prices, contract size, lots, conversion and broker cost.
How a natural gas rollover adjustment is modeled
Contract-series gap = new reference price − expiring reference price
Gap neutralizer = −1 × direction sign × contract-series gap
Signed price adjustment = gap neutralizer − entered broker rollover cost
Signed cash adjustment = signed price adjustment × contract size × lots × quote-to-account rate
Every value is entered manually. Verify the exact broker-server symbol, account, direction, unit and schedule before relying on the arithmetic.
Enter one natural-gas contract-series change
Use broker-published reference prices and adjustment terms for the exact event. Some products expire or cash-settle rather than roll, so the calculator never decides whether this model applies.

How a natural gas rollover adjustment is modeled
Gap neutralizer = −1 × direction sign × contract-series gap
Signed price adjustment = gap neutralizer − entered broker rollover cost
Signed cash adjustment = signed price adjustment × contract size × lots × quote-to-account rate
A futures-linked natural-gas CFD can reference a particular futures month. This model calculates a direction-aware neutralizer for an entered old-to-new reference-price gap, then subtracts a separately entered broker cost.
That cash-neutralizer convention is not universal. FXCM states that its expiring NGAS position is closed and associated orders are cancelled. IG describes natural-gas futures CFDs as expiring and cash settled, while its undated commodity funding is a separate daily adjustment.
Use this calculator only when the broker documents a matching cash-adjustment method. It does not reconstruct forced closure, a new entry, spread, slippage, daily funding or the economics of carrying exposure across futures months.
A careful natural-gas rollover workflow
- Confirm that the exact natural-gas CFD is futures-linked and scheduled to change reference series.
- Determine whether the broker cash-adjusts, cash-settles, closes and reopens, closes at expiry or does not roll the product.
- Record old and new reference prices on the same documented basis and timestamp.
- Verify direction, lots, contract size, profit currency and account conversion.
- Enter a broker rollover cost only when its unit and sign treatment are documented.
- After the event, reconcile old-position P/L, any new position and every cash entry with the statement.
Audited worked example
The audited example uses a long 1-lot position, contract size 100, an expiring reference of USD 3.00, a new reference of USD 3.12, an entered USD 0.01 broker cost and USD-to-USD conversion 1. The +USD 0.12 series gap has a −USD 12.00 long neutralizer; after the USD 1.00 entered cost, the modeled adjustment is −USD 13.00. The same inputs for a short produce +USD 11.00.
How to interpret it
The −USD 13.00 long result is conditional arithmetic, not a forecast or statement entry. If the product expires, cash-settles, closes and reopens or uses forward-curve funding instead, this model is not a complete reconciliation.
Margin, overnight swap and contract rollover answer different questions
Margin is broker-reserved account collateral under an entered calculation convention. Overnight swap or financing is a broker-defined debit or credit for carrying an energy CFD across daily boundaries. A contract rollover adjustment can address a price gap when a futures-linked CFD changes its reference series. None of these amounts is the same as price profit, maximum loss or ownership of physical energy.
| Amount | Primary driver | Timing | Not equivalent to |
|---|---|---|---|
| Required margin | Broker product and account rules | Opening and while exposure remains | Maximum loss or trade cost |
| Overnight swap | Signed rate, unit and daily schedule | Broker rollover boundaries | Contract-series price gap |
| Rollover adjustment | Old/new reference prices and broker policy | Reference-series change | Daily financing or guaranteed neutrality |
Keep the three records separate until each uses the same broker symbol, account currency and observation basis. An undated product can have daily funding without a futures-series cash adjustment, while an expiring natural-gas CFD can close rather than roll.
Assumptions and limits
- No contract calendar, futures curve, settlement price, broker event or live natural-gas price is retrieved.
- The model assumes a cash neutralizer plus a direction-independent entered debit; broker methods can differ.
- Expiration, cash settlement, close-and-reopen execution, realized P/L, slippage and new spread are not reconstructed.
- Negative reference prices are accepted for arithmetic, but broker platform and margin rules can change in extreme conditions.
- The calculator does not determine whether contango, backwardation or rolling exposure is desirable.
- The output is reconciliation arithmetic, not a rollover instruction, forecast or financial advice.
Where to verify natural-gas CFD account-economics inputs
Open the specification for the exact symbol on the same broker server and account type. Record calculation mode, trade contract size, tick size and value, quote or profit currency, initial margin, margin rate, swap mode, signed long and short swap values, daily rollover multipliers and any product expiration. MetaQuotes documents the available properties; the broker supplies their current values.
Then determine whether NGAS, NATGAS, XNGUSD or the exact server symbol is undated, spot-style, expiring or tied to a named natural-gas futures month. Check daily funding, expiry or series-change dates, reference prices, spread or markup treatment and whether positions are cash-adjusted, closed and reopened, closed at expiry or not rolled. The display label alone does not answer those questions.
For a completed trade, the broker statement is authoritative for account activity. Reconcile each debit or credit using confirmed position size, rate unit, event time and conversion. The calculator is designed to expose assumptions and support that reconciliation; it cannot replace the contractual product terms or determine tax and legal treatment.
Frequently asked questions
- Calculate new reference minus expiring reference, apply the opposite direction sign as a gap neutralizer, subtract entered broker cost, then multiply by contract size, lots and conversion.
- No. A product can expire, cash-settle, close at expiry, close and reopen, or use another adjustment method. Verify the broker event terms first.
- They describe only the sign of the entered new-minus-old reference-price gap. The calculator does not forecast the futures curve or recommend a trade.
- A reference jump affects modeled long and short exposure oppositely, so the arithmetic applies +1 for long and -1 for short before reversing the gap.
- It is a nonnegative debit in gas price units, separate from the direction-aware gap neutralizer. Enter it only when its unit and treatment are documented.
- No. Closure P/L, a new opening fill, spread, slippage, daily funding and new-position terms require separate records and calculations.
- No. Old and new references, event date, contract calendar, broker method, contract size and conversion all remain entered and unverified.
- No. It is conditional arithmetic for one disclosed convention, not a forecast, order instruction or promise of an account entry.
