Inside this article

When trading a CFD labelled NAS100, a price change and a later cash entry may be connected to a dividend adjustment. That does not make every decline mechanical, nor does receiving a credit create free profit. The practical challenge is to read the contract, quote and account statement together. This guide provides a reconciliation method using entirely hypothetical examples. None of its prices or cash amounts is a market quote for 15 October 2026, and none is a forecast of an upcoming dividend.

Identify the instrument before interpreting its chart

NAS100 is a platform label, not a complete description of every economic term. Record the full symbol, broker, currency, contract size and whether the product is a cash CFD or references a futures contract. Do not transfer one contract's adjustment rules to another merely because both refer to the Nasdaq-100. Comparing charts also requires this identification. An indicative index level, a futures price and the executable CFD are not the same operational data series, even when their broad direction often looks similar.

What an adjustment can represent

IG's documentation describes CFD adjustments that account for dividend effects on the underlying, with credits to long positions and debits to short positions under the applicable treatment. This is a documented contract mechanism, not a universal numerical rule for every broker. Holding a CFD is not the same as directly owning the underlying shares. The decisive source for the amount, eligible exposure and booking method is the specification applicable to the actual product and contracting entity. Use the provider's explanation as evidence, not as a substitute for identifying your instrument.

Separate the price result, cash adjustment and costs

Our review worksheet separates three components: the economic effect of price movement, the documented cash adjustment and the costs. They may arrive at different times or appear in different statement fields. Their sum explains the result; it does not rewrite the historical chart. Keep any price loss in the position record and add the adjustment as a separate item with a source reference. This makes it possible to assess the net result without incorrectly treating every cash credit as additional trading skill.

A hypothetical offset calculation

Imagine a cash CFD at 10,000 points and a theoretical dividend effect of 10 points. Assume a long position of 0.5 lots and, solely for this example, a contract value of EUR 2 per index point per lot. Exposure is therefore EUR 1 per point. An isolated decline from 10,000 to 9,990 produces a EUR 10 price loss. If the contract provides and books a EUR 10 credit, the total before costs is zero. Under these assumptions the credit offsets the other component; it is not an additional benefit independent of the price change.

Add a separate market move

Keep the same example but add a 30-point market decline on top of the 10-point dividend effect. The hypothetical ending price is 9,960 and the position's price result is minus EUR 40. A EUR 10 credit leaves a EUR 30 loss before costs. It would be wrong to attribute the whole candle to the dividend or claim the adjustment eliminated the loss. This arithmetic illustrates overlapping effects. It does not provide an automatic causal decomposition for a real market event when the underlying evidence is incomplete.

The short side does not manufacture free arbitrage

Under a symmetrical adjustment assumption, a short position would benefit from the isolated mechanical price decrease but receive a corresponding debit. Spreads, commissions and other conditions would still matter. This example is not an instruction to open a position before an adjustment. Its purpose is to remove the idea that selecting the right side guarantees a cash benefit. A dividend schedule is neither an independent trade thesis nor a substitute for understanding execution risk and the specific contract terms.

Point value comes before lot count

A hypothetical cash amount can be checked as recognized points multiplied by point value per lot multiplied by volume, but only when those are the contract's actual units. Some statements provide a cash figure directly. Do not borrow another broker's multiplier or confuse a tick, an index point and the number of decimals displayed on screen. Keep the original units alongside the conversion. A tenfold discrepancy may result from a wrong multiplier rather than an extraordinary market event, so diagnose the arithmetic before drawing a market conclusion.

Expected credits and booked credits are different records

A broker schedule can help preparation, but it is not yet a transaction in the account. Record the consulted estimate, its date and the actual booked amount separately. If they differ, retain both versions and seek a documented explanation. Do not revise the old estimate silently to make it look accurate in hindsight. IG also notes special treatment can apply to special dividends. The practical principle is to avoid turning a general table into certainty about every event and every eligible position.

Do not invent the eligibility time

A dividend date, the time used to determine eligible positions and the time a cash adjustment appears may be different. Find the product-specific rule and broker confirmation, especially for trades opened or closed near a boundary. Record timestamps and time zones rather than only a handwritten date. A phone clock is not automatically the server clock. A reproducible comparison must distinguish a timing discrepancy from a wrong volume, an incorrect sign or an adjustment that has not yet been booked.

Stops and pending orders need a separate check

Knowing that an adjustment exists does not establish how stops, limits or pending orders are treated. Do not move a protective level based on a generic rule taken from a different provider. Consult the applicable terms and use documentation or an appropriate demo environment for technical checks. A monetary adjustment does not guarantee execution of a stop at the intended price. Separate the order outcome from the accounting explanation in the review because these are different questions and may need different evidence.

Costs and currencies can prevent an exact offset

The zero-result example intentionally excluded costs, rounding and currency conversions. In a real account, reconcile the treatment of each item rather than promising perfect neutrality. If the product and account use different currencies, document the conversion used for both the price result and cash entry. Do not select a retrospective exchange rate merely because it makes the totals match. A small residual can be explainable, but it should be tied to a verifiable item rather than dismissed automatically as immaterial.

Classify the adjustment properly in the journal

A contract-related adjustment is not ordinarily a fresh contribution from the account owner. Our proposed journal classification gives it a separate economic category linked to the instrument and, where evidence permits, to the affected exposure. Preserve both the gross price result and the overall result. If the statement assigns an entry to the account rather than an identifiable position, do not invent a ticket. Keep the entry at account level and explain any allocation rule used for analytical purposes.

A cash credit must not become an extra winning trade

Suppose a journal imports ten positions and one cash adjustment. Treating the latter as an eleventh positive trade could change win rate and decision count even though no new entry occurred. Check record identity and economic category to prevent this. The monetary result may change, but the number of trading decisions must not be increased arbitrarily. This is a proposed measurement test, not an allegation that Disciply or any named competitor has the described defect. Test the data rather than assuming an implementation's behavior.

Compare charts without inventing signals

When the CFD chart contains a discontinuity that differs from a reference chart, first compare symbol, contract type, session, timestamps and treatment of historical prices. Save both series' metadata and a screenshot. Do not automatically call the discrepancy a liquidity sweep or market manipulation. Without compatible data you cannot isolate the cause. Disciply's educational method starts with the context of the observation before interpreting structure or patterns. A visually striking candle is not enough to establish the trader's preferred explanation.

A repeatable reconciliation procedure

Choose a past event visible in the statement. Record the contract, eligible exposure and broker communication, then check the adjustment's sign, units, amount and time. Reconstruct price result plus adjustments minus costs, taking care not to subtract a commission already included in a net figure. Finally reconcile starting and ending balance with all other movements in the period. Keep unexplained differences in a separate list. A process becomes verifiable when another person can reproduce the result from the same source records.

Make a support request that can be investigated

When an amount does not match, provide the exact symbol, account identifier through a secure channel, time window, relevant volume, transaction reference and expected calculation. Do not publish credentials or complete statements in a public chat. Ask which rule produces this adjustment for this exposure. That is more actionable than simply declaring the chart incorrect. Retain the official answer and document any correction without silently replacing the initial observation, so the investigation itself remains traceable.

Risk remains operational as well as accounting-related

Understanding an adjustment does not remove variable spreads, gaps, slippage or position-management mistakes. Evaluate risk using the execution conditions of the actual contract, not the belief that a future credit will recover any loss. A trade still needs an independent entry rationale and an invalidation condition. Its review still needs to distinguish process, outcome and data quality. A well-explained cash entry makes an account easier to understand; it cannot turn an unconfirmed or impulsive decision into a disciplined one.

Handle missing evidence explicitly

The price series may be available while a broker notice or accounting entry is still missing. In that situation the conclusion remains provisional: record what is known and what has not been confirmed. Do not put a theoretical adjustment into realized journal results as though it had arrived. A separate expected-adjustments view can support preparation if clearly distinguished from confirmed transactions. Moving an item from expected to confirmed should leave an evidence trail showing the source and time of verification.

Bring the right questions to the weekly review

Summarize the affected positions, reconciled entries and outstanding investigations. Check whether discrepancies came from units, timing, product identity or import processing; each cause requires a different correction. Do not compare weeks under changed definitions without disclosure. The useful information is not just the final profit but whether you can explain how it was produced. This habit helps avoid both unnecessary alarms and excessive confidence in a result that has not yet been fully checked.
