Index CFD Trading With USDT: Point Values and Dividends

In index CFD trading, equal lots can produce different cash losses from the same 1% market move. On MEXC, NAS100, SPI500 and DJ30 have matching contract multipliers, but their different index levels change the exposure each order creates.

MEXC specifications were reviewed on November 6, 2026. The calculations below distinguish price P&L from financing and any applicable dividend entries.

All trade prices, swap rates and outcomes in the examples below are hypothetical. They are not live quotes or recommended trades.

Choose the Index Before Comparing Point Moves

MEXC uses separate CFD symbols for three major U.S. equity benchmarks:

• NAS100 provides Nasdaq-100 exposure. Nasdaq describes its benchmark as tracking 100 of the largest Nasdaq-listed non-financial companies, with modified market-capitalization weighting.
• SPI500 is MEXC’s S&P index cash CFD. S&P Dow Jones Indices describes the S&P 500 as a benchmark of leading large-cap U.S. companies.
• DJ30 is MEXC’s Dow Jones index cash CFD. Its underlying benchmark is price-weighted and covers 30 U.S. blue-chip companies.

An index CFD gives exposure to benchmark price changes without ownership of its constituent shares. A Nasdaq-100 position also does not represent every company listed on Nasdaq.

Calculate Point Value in Index CFD Trading

A full index point means a move such as 24,000 to 24,001. It should not be confused with the smallest quoted decimal increment.

The reviewed MEXC specifications showed a contract size of 1, a minimum order of 0.1 lot and a quantity step of 0.1 lot for all three USD-priced CFDs. Their price sensitivity is:

• 1 lot: $1 per full index point.
• 0.2 lot: $0.20 per full index point.
• 0.1 lot: $0.10 per full index point.

For a long position:

Price-based P&L = (closing sell price − opening buy price) × contract size × lots.

Suppose a NAS100 buy fills at 24,000.50 and the closing sell fills at 24,200.50. At 0.2 lot:

200 points × 1 × 0.2 = $40 profit before separately charged fees and adjustments.

For a short position, reverse the price subtraction: opening sell price minus closing buy price. A 200-point rise would produce a $40 price loss on a 0.2-lot short.

Use executable buy and sell prices in the calculation. Their difference already reflects the spread; subtracting that same spread again would count it twice. Commissions, swaps and any separate account adjustments still need to be included.

Equal Lots Do Not Mean Equal Percentage Exposure

Assume NAS100 is at 24,000, SPI500 at 6,000 and DJ30 at 48,000. With a contract multiplier of 1, opening notional exposure is:

Index level × lots.

At 0.2 lot, those positions represent $4,800, $1,200 and $9,600 respectively. If each index falls exactly 1%, the price losses on long positions would be:

• NAS100: 240 points × $0.20 = $48.
• SPI500: 60 points × $0.20 = $12.
• DJ30: 480 points × $0.20 = $96.

The same quantity creates the same dollar sensitivity per full point, but the indices have different starting levels.

To match the $4,800 opening exposure in this example, the quantities would be 0.2 lot NAS100, 0.8 lot SPI500 or 0.1 lot DJ30. Each would lose $48 from an exact 1% decline before costs.

Matching notional exposure standardizes the percentage-move comparison. It does not establish equal volatility or equal stop-loss risk. For example, a NAS100 entry-to-stop distance of 80 points at 0.2 lot represents a $16 price loss before costs, assuming execution at the stop. Opening notional alone does not tell you that loss.

The margin required to open the position is a separate calculation. See CFD Margin and Leverage Explained: Formulas & Examples.

Treat Dividend Adjustments as Part of the Position's Result

When constituent shares trade ex-dividend, the dividend effect can reduce a price-return index level, all else equal. Cash index CFDs may apply an account adjustment to offset that mechanical effect: typically a credit for a qualifying long position and a debit for a short position.

Assume a hypothetical cash index CFD has a $0.20 point value, a six-point dividend-related reduction and an adjustment matching that reduction:

• Long: price P&L falls by $1.20, while the account receives a $1.20 credit.
• Short: price P&L rises by $1.20, while the account receives a $1.20 debit.

The combined effect is zero before other market moves and charges. Counting only the credit or only the price drop would misstate the result.

This is a general illustration, not an announced MEXC payment. For a MEXC position, confirm whether an adjustment applies and check its eligibility cutoff, amount, units and posting time through current instrument notices or support.

Account for Currency-Mode Swaps and Friday Rollover

MEXC’s CFD FAQ specifies currency-mode swaps for stock indices:

Swap amount = lots × the applicable long or short swap value × chargeable days.

At an assumed long swap of −$5 per lot per day, 0.2 lot incurs $1 for one chargeable day or $3 for a three-day rollover.

The reviewed NAS100, SPI500 and DJ30 pages displayed Friday as their three-day swap day. Rates and settings can change; check the current values under Info before holding overnight.

MEXC states a daily settlement cutoff of 23:59 platform time, using UTC+3 during daylight saving time and UTC+2 during standard time. Check the trading session as well as that cutoff when planning an exit. See CFD Trading Hours: Forex, Gold, Oil and Indices.

Put the Calculations Into a MEXC Order

Eligible users can activate a CFD account through MEXC CFD and transfer USDT from their Spot account. MEXC converts it at 1:1 into USDx, its internal CFD accounting and settlement unit.

Record the symbol, lots, dollar value per point, intended entry and stop, and holding period before submitting the order. Check the permitted quantity and current margin, commission and swap requirements.

When closing, use the existing position’s close action. MEXC supports independent long and short positions, so a fresh opposite-direction order does not automatically close the original position.

After closing, reconcile the entry and exit fills with commissions, swaps and any applicable dividend entries. For the cost breakdown, see CFD Trading Costs Explained: Spreads, Fees and Swaps.

Risk Warning

Index diversification does not remove leveraged trading risk. Gaps, wider spreads and slippage can make a loss exceed a stop-based estimate, and insufficient account equity can trigger liquidation. Product availability depends on jurisdiction and account eligibility.
