How to Trade the Nasdaq 100 (US100) as a CFD: Point Value, Margin and Position Size on MT5

Educational content. This article explains what the Nasdaq-100 is, what a US100 CFD position is worth and locks on the MT5 platform, and how stop distance sets position size. It does not constitute investment advice or a recommendation. CFD trading carries significant risk of loss and may not be suitable for all investors.

To trade the Nasdaq 100 as a CFD, you open a position on US100, the cash-settled contract on the index of the 100 largest non-financial companies listed on Nasdaq. One lot equals one index point, so a 1.00 move is worth USD 1 per lot. At 30,919.75 points and the 1:100 index cap, one lot has a notional value of about USD 30,920 and locks about USD 309 of margin.

This guide covers what the index is made of, what a US100 position is worth, how it compares with US500 per lot, how stop distance sets lot size, how the US session shows up in MT5 server time, and where the risks sit. The figures are arithmetic, not forecasts.

What Is the Nasdaq-100 and How Is It Built?

The Nasdaq-100 is an index of 100 of the largest non-financial companies listed on the Nasdaq Stock Market, weighted by a modified market capitalisation. In plain terms, larger companies carry larger weights, with caps that stop one or a few names from taking over the whole index. Financial companies, including banks and insurers, are not eligible, which is one reason the index is often described as technology-heavy.

The published methodology, from Nasdaq Indexes (consulted 10 October 2026), has three features that matter to a CFD trader:

• Weights are capped at the quarterly rebalance. If a company's weight would exceed 24%, the weights are reduced so that no company is above 20%. A second test applies to the group of companies above 4.5%: if that group adds up to 48% or more, it is cut to 40%.
• Low free-float shares are limited. A security's shares outstanding are capped at three times its free-floating shares when weights are set.
• The list is reviewed once a year. The annual reconstitution, held in December, decides which 100 companies are in the index. Check the current methodology document for the exact thresholds, because index providers can change them.

The consequence is that US100 is a concentrated index. A small number of very large companies hold weights well above the 1% an equal split would give, so their results and share-price moves matter more than those of the other members. The current weights are published by the index provider and change daily with prices. For how weighting methods differ across indices, read how to trade indices.

What Is One Lot of US100 Worth?

One lot of US100 is worth USD 1 per index point, because the contract size is 1 and the profit currency is USD. A position of 0.01 lot is worth USD 0.01 per point, and a position of 10 lots is worth USD 10 per point. The rule is the one in what is contract size in trading: value per point equals contract size times lots.

The table shows the US100 specification next to US500 and US30. All figures are from the Vanto feed snapshot, 10 October 2026.

Two readings follow. The point value is identical, so lot size alone does not tell you how large the exposure is: the index level does. US100 sits between the two: a lot of US30 controls about 1.7 times the notional of a lot of US100, and a lot of US100 controls about 3.95 times that of US500. The direct comparison with US500 is in the next section.

Across all 18 index symbols in the feed, US100 has the second-largest notional per lot in USD, after US30. JP225 is quoted at a higher index level (about 68,940), but in yen, so one lot is only about USD 436. The ranking was computed from the full feed with each profit currency converted to USD at the snapshot mid rate, and it will change as index levels and exchange rates move.

US100 vs US500: Same Lot, Different Exposure

For the same number of lots, US100 carries about 3.95 times the dollar exposure of US500, because 30,919.75 divided by 7,821.28 is 3.953. The point value is the same, USD 1 per lot, but a point on US100 is a much smaller fraction of the price, so the same percentage move is worth far more points. This is the main practical difference between the two contracts, and the one that catches traders who switch between them at a fixed lot size.

Vanto feed snapshot, 10 October 2026. Moves are measured from the ask of 30,919.75 for US100 and 7,821.28 for US500. The percentages are scenarios for arithmetic, not forecasts.

There are two ways to read the table. Holding the lot constant, a 1% move is worth about USD 309 on US100 and about USD 78 on US500. Holding the dollar exposure constant, 1 lot of US100 matches about 3.95 lots of US500, so a trader who wants the same exposure on both uses roughly a quarter of the lot size on US100.

The table does not say which index moves more in percentage terms on a given day. Whether the Nasdaq-100 moves by larger or smaller percentages than the S&P 500 depends on the period, and there are stretches where the two move almost together. Sizing should not rely on it in either direction. The wider S&P 500 picture, including weights and dividends, is in how to trade the S&P 500; this article does not repeat it.

How Much Margin Does US100 Need?

One lot of US100 needs margin equal to 1% of its notional value, which is about USD 309.20 at the snapshot. The 1:100 cap on indices means margin = price x contract size x lots / 100, and it rises and falls with the index level.

Vanto feed snapshot, 10 October 2026, ask 30,919.75. Margin changes with the index level.

The last two columns are always equal. That is the structural fact of a 1:100 cap: margin is 1% of notional, so a 1% adverse move uses up the whole margin. Leverage amplifies losses as well as gains, and for an index that can move 1% in a normal session the cap says little about the risk being taken. The size of the position against the account is what sets the risk. The full mechanics are in what is leverage in trading and what is margin in trading, and margins for all asset classes side by side are in the margin table.

What Happens to a USD 1,000 Account With 1 Lot of US100?

A USD 1,000 account holding 1 lot of US100 is stopped out after a fall of about 845 points, or about 2.7% of the index. The working is below.

1. Margin used: 30,919.75 / 100 = USD 309.20.
2. Stop-out happens when equity falls to 50% of the used margin: 0.5 x 309.20 = USD 154.60.
3. Loss that takes equity from 1,000 to 154.60: 1,000 - 154.60 = USD 845.40.
4. At USD 1 per point per lot, that is 845.4 points, or 845.4 / 30,919.75 = 2.7% of the index.

The margin call level is 100% and the stop-out level is 50% on both Vanto account types; the sequence is explained in what is stop-out level in trading. The account could be wiped out by a move that the margin figure suggested was far away, because the position is about 31 times the account in notional terms (30,919.75 / 1,000). A fast move can also close the position at a worse price than the stop-out level, a risk covered in what is slippage in trading.

How to Size a US100 Position From the Stop Distance

To size a US100 position, divide the amount you are willing to lose by the stop distance in points: lots = risk in USD / stop in points. This works because one lot is exactly USD 1 per point, so the stop distance in points is also the loss in USD per lot. Margin is a check made after sizing, not the starting point.

Illustrative sizing at the ask of 30,919.75. The stop distances are examples, not suggestions of where to place a stop.

The pattern in the table is the useful part. A wider stop does not raise the risk, it lowers the lot size, and the margin drops with it. A tighter stop does the opposite: it allows a larger position, which is then more exposed to the spread and to normal back-and-forth movement, because a 100-point stop is only 0.32% of the index. The spread is paid on entry and counts against the stop distance, a point developed in what is the spread in trading.

The same logic, with the target added, gives the risk-reward ratio; the break-even win rate for each ratio is in what is the risk-reward ratio. The smallest position of 0.01 lot is worth USD 0.01 per point, so even a modest account can size in small steps; see what is minimum lot size in trading.

What Moves the Nasdaq-100?

US100 moves with the expected earnings of its largest members, with US interest-rate expectations and with overall risk appetite. These drivers overlap, so on many days they arrive together.

• Earnings of the largest members. Because of the weight caps described above, a handful of companies still account for a large share of the index. Many large companies report after the US close, which means the reaction appears in the next session's opening range rather than during the report itself.
• Interest rates and Treasury yields. Growth-oriented companies earn a larger part of their value from profits expected far in the future, and higher yields reduce the present value of those profits. The channel is explained in why stocks fall when bond yields rise.
• The Federal Reserve and US data. Rate decisions, inflation and jobs reports change the expected path of rates. The release mechanics are the same as on the dollar: see how FOMC meetings affect the US dollar, how CPI affects the US dollar and how NFP affects the US dollar.
• Risk sentiment. The VIX measures expected S&P 500 volatility and tends to rise when US equities fall, which makes it a context gauge for US100 as well; see how to trade the VIX.

Because the weights are concentrated, a news item about one very large member can move US100 more than it moves US500 or the Dow. That is a property of the index design, and it works in both directions.

When Does the US Session Start in MT5 Server Time?

The US cash session opens at 09:30 New York time and closes at 16:00 New York time, which is 16:30 and 23:00 on a Vanto MT5 chart, because the server runs 7 hours ahead of New York. The offset holds all year, because the server time follows US daylight saving: it is UTC+3 in summer and UTC+2 in winter. For a trader in Southeast Asia or Japan, that means the main US session falls late in the evening or overnight, which is a practical reason to plan stops before going offline.

The line to remember is the gap between the second and fourth rows. A report released after the close is priced in the next session's opening, and a stop-loss that sits inside the gap fills at the first available price, not at the stop level. How the quote is formed outside the cash session depends on the symbol's trading sessions and its price source, so read the specification in the MT5 Market Watch instead of assuming continuous trading. For the mechanics of the Friday-to-Monday and overnight gaps, see the examples in CFD index trading.

What Does Holding US100 Cost?

Holding a US100 position costs the spread on entry and the overnight swap, and a CFD holder also receives a dividend adjustment instead of the dividend itself. The three costs behave differently.

• The spread is paid on entry and is wider around news and at the market open. On the snapshot the spread in points is wider on US100 than on US500 because the price is almost four times higher, but as a share of the price the two are close. For that reason the spread alone is not a reason to choose one over the other.
• Overnight swap. On US100 the long position is debited and the short position is credited. Friday is the triple swap day, so a position held through Friday's rollover is charged three nights, not Wednesday as on forex. The reason and the calendar are in what is triple swap day and what is swap in trading. The current rates are in the trading calculator, because they change.
• Dividend adjustments. A CFD holder does not receive dividends. On the ex-dividend dates of constituents, longs are credited and shorts debited the equivalent amount. CFD index trading explains the mechanism.

Can You Hold a Buy and a Sell on US100 at the Same Time?

Yes, MT5 accounts at Vanto run in hedging mode, so a buy and a sell on US100 can be open at the same time as separate positions. Each position has its own stop, target and swap, and the net exposure is the difference between the two. The consequences for margin and for stop-outs depend on the platform's rules, which are explained in hedging vs netting in MT5. This article does not state a margin figure for opposite positions, because that setting can change.

Common Mistakes and When the Rules of Thumb Break

Most errors on US100 come from carrying a habit built on another instrument across to it. The list below covers the ones that follow directly from the arithmetic above.

• Using the same lot size as on US500. The same lot carries about 3.95 times the dollar exposure, so a 1% move costs about USD 309 per lot, not about USD 78.
• Sizing by the margin. A trader who asks "can I afford USD 309 of margin?" has not asked how much the position can lose. A 1% move equals the whole margin, as the table shows.
• Treating the stop as a guarantee. A stop-loss becomes a market order when the price is reached. A gap at the open or a fast move around a data release fills at the next available price.
• Using a stop that is smaller than normal movement. A stop of 100 points is 0.32% of the index. A move of that size can happen within minutes around the US open, so a tight stop is hit by ordinary noise, and the spread paid on entry makes it worse.
• Assuming the correlation with US500 is fixed. The two indices overlap in their largest members, so they usually move in the same direction, but the size of the move differs and the gap between them can widen. Holding both is not diversification in the usual sense.
• Forgetting the evening hours. For a trader in Asia the US session is late in the local evening or overnight. A position opened before the close of the local day is still exposed during the US session, when the largest moves often happen.

The rule of thumb that leverage "only matters if you use all of it" breaks on indices for the reason above: at 1:100 the margin is crossed by a 1% move, so even a position far smaller than the account's maximum can be stopped out by a move of ordinary size. Leverage amplifies losses as well as gains.

Frequently Asked Questions

What is US100?

US100 is the MT5 symbol for the Nasdaq-100 CFD on Vanto, a cash-settled contract on the index of 100 large non-financial Nasdaq-listed companies. The description in the feed is "US Tech 100 CFD".

What is the value of one point on US100?

One point is worth USD 1 per lot. A position of 0.01 lot is worth USD 0.01 per point, and a position of 10 lots is worth USD 10 per point. The value does not change with the index level.

How much margin does 1 lot of US100 need?

About USD 309.20 at the Vanto feed snapshot of 10 October 2026 and the 1:100 index cap. The margin is 1% of the notional value, so at 35,000 points it would be USD 350 per lot.

What is the difference between US100 and US500?

US100 tracks the Nasdaq-100 (100 companies, concentrated in technology and growth) and US500 tracks the S&P 500 (about 500 companies). Both are worth USD 1 per point per lot, but US100 is priced about 3.95 times higher in the snapshot, so the same lot carries about 3.95 times the exposure.

Does US100 have a triple swap day?

Yes, Friday, as on the other index symbols in the feed, not Wednesday as on forex pairs. Longs are debited and shorts credited on US100, and the rates change, so check them in the calculator.

Why can a US100 stop-loss fill at a worse price than set?

A stop-loss becomes a market order when the stop level is reached, so it fills at the next available price. When the market gaps, for example at the US open after an after-hours earnings release, that price can be beyond the stop level.
