NAS100 Position Size Calculator

What makes NAS100 position sizing different

NAS100 is quoted as an index level, not as a currency pair, so the price you see is the value of the underlying cash index itself. That means the distance from entry to stop is measured in index points, and the cash value of one point depends on your contract size and on the currency the index is quoted in. If your account is held in a different currency, the calculator applies the conversion, because the P&L of the trade is generated in the index's quote currency and then translated into your account currency.

Because NAS100 is a CFD on a cash index, there is no fixed lot standard the way there is in FX. Brokers define their own contract sizes, often expressed as a cash amount per index point, and that number is what turns a point move into money. The calculator above is the source of the live contract specification and point value for your account, so treat the output as the authoritative figure for the trade you are about to place rather than relying on a remembered value.

What actually moves NAS100

NAS100 is dominated by large US technology companies, so its direction is driven primarily by US technology earnings and by Federal Reserve policy. Earnings reports from the index's largest constituents change the market's view of future cash flows for the sector that carries the most weight, and those moves often happen outside regular cash hours, which is why NAS100 can gap and why a stop placed on the chart may not be filled at the level you chose.

Federal Reserve policy works through the discount rate applied to those future cash flows and through the general appetite for risk. Shifts in rate expectations tend to hit long-duration growth equities hardest, and NAS100 is the most concentrated large-cap growth index in the US. The two drivers can pull in the same direction or oppose each other, and when they conflict, intraday volatility usually rises, which directly affects how much room your stop needs and therefore how large your position can be.

Liquidity and execution notes

Liquidity is deepest during the US cash session, when the underlying constituents are trading and the index's official level is being calculated. Around that session the spread is typically at its tightest and slippage is smaller. Outside it, in the Asian session and the late European session, the CFD still trades but the underlying cash market is closed, so spreads widen, depth thins and price can jump between prints. The US cash open and the release of US data are the points where volatility and spread both expand sharply.

Before entering, check the scheduled US technology earnings and any Federal Reserve communication, because both can invalidate a tight stop within seconds. Size the position from the stop distance you are actually willing to place, not from the smallest lot your platform allows, and remember that a stop is not guaranteed at your level during gaps or thin liquidity. If your account currency differs from the index's quote currency, confirm the conversion the calculator is applying before you commit, so the risk you take matches the risk you intended.
