FTSE 100 Index (UK100) Trading Guide 2024

The UK100's pip value of 1 means that for every full point the index moves, a trader holding a single contract gains or loses exactly £1 (or the account currency equivalent). That clean, whole-number structure makes position sizing arithmetic straightforward compared to forex pairs where pip values shift with exchange rates.

The typical spread is 1.5 points. On a standard contract, that means entering a trade costs 1.5 units of account currency in spread before any price movement occurs. At the FTSE 100's historical average daily range of roughly 60–80 points, the 1.5-point spread represents approximately 2% of expected daily movement — a relatively low friction cost for a day trader.

Contract size is 1, meaning each lot equals one full unit of the index. Unlike some equity indices where contract multipliers inflate exposure dramatically, the UK100 keeps the relationship between lot size and monetary exposure linear. A trader holding 5 lots on a 50-point move realises a £250 gain or loss — no hidden multipliers to account for.

The index tracks 100 constituents but is heavily concentrated. As of 2024, the top 10 holdings account for roughly 40% of the index weight, with energy, mining, and financial stocks dominating. That concentration means commodity price swings — particularly oil — can move the FTSE 100 disproportionately relative to broader economic data.

The FTSE 100 trades from 01:00 UTC Monday through 22:00 UTC Friday in the CFD market, but not all hours carry equal opportunity. The session structure divides into three distinct windows, each with a different volatility and liquidity profile.

The Pre-Market session (01:00–08:00 UTC) is dominated by Asian market participants reacting to overnight news from Wall Street and Asia-Pacific. Volume is thin, spreads can widen beyond the typical 1.5 points, and price gaps are more common. Moves during this window often lack follow-through.

The Regular session (08:00–16:30 UTC) is where the FTSE 100 generates the majority of its daily volume. The London Stock Exchange opens at 08:00 UTC, and the first 90 minutes typically see the highest intraday volatility as institutional desks react to overnight developments, European economic data, and opening auction results. A second volatility spike occurs at 13:30 UTC when US economic data releases coincide with the New York session open — this overlap between London and New York is historically the single most active 2-hour window for UK100 trading.

The Extended session (16:30–22:00 UTC) continues after the LSE closes, driven primarily by US market sentiment and futures pricing. Liquidity drops noticeably after 17:30 UTC, and price action often tracks the S&P 500 more closely than UK-specific fundamentals during this period.

For traders focused on trend continuation, the 08:00–10:00 UTC and 13:30–15:30 UTC windows have historically offered the clearest directional moves with adequate liquidity to support entries and exits without significant slippage.

A counterintuitive feature of the FTSE 100: a weaker British pound often pushes the index higher. Because roughly 75% of FTSE 100 constituent revenues are generated outside the UK, sterling depreciation inflates the sterling value of overseas earnings when repatriated. The September 2022 mini-budget crisis illustrated this dynamic — the pound fell sharply while the FTSE 100 briefly outperformed European peers on currency translation effects.

Bank of England (BoE) monetary policy decisions move the index directly. Rate decisions are published at 12:00 UTC on scheduled Monetary Policy Committee meeting days, and the accompanying statement often generates 40–80 point swings within minutes. The BoE calendar for 2024 schedules eight MPC meetings, each a potential volatility event.

Commodity prices carry outsized influence due to the index's composition. The energy sector (BP, Shell) and mining sector (Rio Tinto, Glencore, Anglo American) collectively represent over 20% of index weight. A sustained 10% move in Brent crude or copper prices typically registers as a measurable directional bias in UK100 price action.

US macroeconomic data — particularly Non-Farm Payrolls (first Friday of each month, 13:30 UTC) and Federal Reserve rate decisions — routinely generate FTSE 100 moves of 30–60 points. The index's correlation with the S&P 500 on high-impact US data days exceeds 0.8 according to historical analysis, meaning American economic surprises transmit rapidly to London.

Geopolitical risk events, Brexit-related regulatory developments, and UK GDP releases (published by the ONS quarterly) round out the primary fundamental drivers.

Effective risk management on the UK100 starts with understanding daily range context. The FTSE 100's average true range (ATR) on a 14-day basis has historically sat between 50 and 120 points depending on macro conditions. During the 2020 COVID volatility peak, daily ranges exceeded 300 points on multiple occasions. Stop placement below the ATR threshold risks being triggered by normal intraday noise.

A practical framework used by professional index traders places initial stops at 1.0–1.5× the 14-day ATR from the entry point. On a day with a 70-point ATR reading, that translates to a stop 70–105 points from entry. With a pip value of 1, a 100-point stop on a single contract represents a £100 maximum loss — making position sizing arithmetic clean and scalable.

Position sizing should be derived from account risk percentage rather than fixed lot sizes. A trader with a £10,000 account risking 1% per trade (£100) and using a 100-point stop would trade 1 contract. Scaling to 2% risk allows 2 contracts on the same setup. This percentage-based approach keeps risk consistent as account equity fluctuates.

Correlation risk deserves attention when holding multiple index positions simultaneously. The FTSE 100 carries a historical correlation above 0.7 with the DAX 40 and CAC 40 during normal market conditions. Holding concurrent long positions across European indices does not provide the diversification that holding four separate positions might imply — effective exposure is considerably higher than it appears on paper.

Trailing stops become particularly relevant during trending sessions. After the London open establishes a directional bias, a trailing stop set 30–40 points behind price can capture the bulk of a trend move while protecting accumulated gains if price reverses sharply on unexpected news.
