United Kingdom Market Details

Lse Applicability All liquid FTSE 100 and FTSE 350 index exposure and large-cap UK shares. Retail access is predominantly via FCA-regulated CFDs and spread bets, or the exchange-traded FTSE 100 future on ICE Futures Europe
Fca Compliance Fully FCA-regulated. Exchange-traded FTSE 100 futures clear through ICE Clear Europe; CFDs and spread bets are offered by FCA-authorised firms subject to retail leverage caps and negative balance protection
Lot Sizes 1 ICE future = £10 per index point (notional ≈ £10 × index level, e.g. ~£104,000 at 10,400). Spread bets/CFDs are sized at a trader-chosen £/point (commonly £1-£5) • No liquid standalone retail future; exposure via FCA-regulated CFD/spread bet on the sector or via constituent banks (Barclays, HSBC, Lloyds, NatWest, Standard Chartered) • Sector exposure via CFD/spread bet or constituent shares; no liquid standalone retail future • Exchange-traded single-stock futures are effectively defunct for UK retail; single-name leverage is via FCA CFDs/spread bets. Buying the underlying shares attracts 0.5% SDRT; derivatives do not
Trading Hours 8:00 AM - 4:30 PM London time (GMT/BST) for LSE cash equities. The FTSE 100 future trades extended hours on ICE (~01:00-21:00 London); FCA spread-bet/CFD index prices are quoted nearly 24 hours on weekdays
Optimal Timeframes 15-minute and hourly for day trading setups • 4-hour and daily for multi-day positions • Multiple timeframe divergence alignment
Expiry Considerations FTSE 100 futures expire quarterly (third Friday of March, June, September, December); divergences near expiry may be distorted by rollover activity. Cash CFD/spread-bet index products have no expiry but incur daily financing on positions held overnight
Tax Implications Gains on exchange-traded futures and CFDs fall under Capital Gains Tax (18% within the basic-rate band, 24% higher/additional rate; £3,000 annual exempt amount). Spread-bet gains are exempt from CGT and stamp duty for individuals, unless HMRC deems trading your profession. SDRT (0.5%) applies to physical UK share purchases, not to derivatives

Frequently Asked Questions

How do I spot divergence on a chart?

Visual steps: 1) Look at recent price swings - identify clear highs and lows. 2) Place RSI indicator below price chart. 3) Draw a line connecting two recent price lows (for bullish) or highs (for bearish). 4) Draw a line connecting RSI values at those same points. 5) If lines slope in opposite directions = divergence. For bullish: price line slopes down, RSI line slopes up. For bearish: price line slopes up, RSI line slopes down. Most charting platforms let you draw lines on RSI to make comparison easier.

Can I trade divergence on any timeframe?

Yes, divergence works on any timeframe, but characteristics differ: 1-5 minute: many signals, most are noise, low reliability. 15-60 minute: good for intraday, moderate reliability. 4-hour/Daily: best for swing trading, higher reliability. Weekly: major reversals, very reliable but rare. Recommendation: start with hourly or daily timeframe. Shorter timeframes have more false signals. Higher timeframes give fewer but more reliable signals. Match timeframe to your trading style and holding period.

Should I trade every divergence I see?

No, selective trading is key. Filter divergences by: 1) Trend context - regular divergence best at trend extremes after extended moves. 2) RSI level - should be in overbought/oversold zones. 3) Confirmation - wait for reversal candle. 4) Support/resistance - divergence at key levels is stronger. 5) Higher timeframe alignment - check if bigger picture supports the trade. Trade only high-quality setups. Missing mediocre setups is better than taking losses on weak signals. Quality over quantity.

What's the difference between regular and hidden divergence?

Key difference is what they signal: Regular divergence: counter-trend signal, suggests reversal. Price makes new extreme but RSI doesn't confirm = trend exhaustion. Hidden divergence: trend continuation signal. Price pulls back but doesn't make new extreme, RSI makes new extreme = trend resuming. Easy distinction: Regular = price at NEW extreme, RSI not confirming. Hidden = price NOT at new extreme (pullback), RSI at new extreme. Regular is riskier (counter-trend), hidden is safer (with-trend).

How long should I wait for divergence to work?

General guidelines by timeframe: 15-min divergence: should show results in 1-4 hours. Hourly divergence: should show results in 1-2 days. Daily divergence: should show results in 3-10 days. If timeframe-appropriate time passes without progress, reassess: 1) Is the divergence extending (making bigger divergence)? Wait if setup improves. 2) Is it failing (price breaking divergence extreme)? Exit at stop. 3) Is it consolidating? May need patience. Use time stops if price goes nowhere - your capital can be better used elsewhere.

How do I trade hidden divergence effectively?

Hidden divergence trading approach: 1) First confirm the trend is intact (higher highs/lows for uptrend). 2) Wait for pullback within the trend. 3) Look for hidden divergence: price higher low + RSI lower low (bullish). 4) Enter when RSI turns back up from its lower low. 5) Stop below the price higher low. 6) Target: new trend highs. Advantage: you're trading with the trend, so higher success rate. Key insight: hidden divergence shows the trend is resuming despite temporary RSI weakness. The market is using pullback to gather energy for continuation.

How do I combine RSI divergence with MACD divergence?

Dual divergence is powerful: 1) Identify divergence on RSI. 2) Check if MACD shows same divergence (price extreme, MACD not confirming). 3) Both showing same divergence = high probability signal. 4) Trade with higher confidence and potentially larger size. Different information: RSI measures momentum speed. MACD measures trend momentum. Both disagreeing with price = strong exhaustion signal. If they conflict (RSI shows divergence, MACD doesn't): wait for alignment or trade with reduced conviction. Dual confirmation significantly improves win rate.

What makes divergence fail most often?

Top failure causes: 1) Strong trend override - powerful trends can ignore divergence for extended periods. ADX > 40 divergences less reliable. 2) No confirmation - entering just on divergence without waiting for reversal sign. 3) Poor context - divergence in middle of range vs at clear trend extreme. 4) News events - fundamentals can override technical signals. 5) Weak divergence - slight RSI non-confirmation isn't significant. 6) Early entry - entering on first divergence when it extends to larger divergence. Prevention: use filters (trend strength, confirmation, S/R confluence), accept some failure as normal, size appropriately.

How does volatility affect divergence trading?

Volatility impacts: High volatility: wider stops needed, divergence swings are larger, confirmations are clearer but price moves fast. Low volatility: tighter stops possible, divergence may be subtle, moves are slower to develop. Volatility-index context (VFTSE, the FTSE 100 volatility index): VFTSE > 25: divergences may be more reliable (extreme sentiment), but use wider stops. VFTSE < 14: divergences in a complacent market may need more confirmation. Adjustment: in high volatility, wait for stronger confirmation and use ATR-based stops. In low volatility, signals may be weaker but trade more precise levels.

Can divergence be used with options instead of futures?

Yes, divergence works with options: Advantages: defined risk (option premium is max loss), potentially higher percentage returns, can use spreads for defined risk/reward. Considerations: theta decay works against you, need sufficient time to expiration, IV impacts premium. Strategy adaptations: buy slightly ITM or ATM options for divergence trades (less theta/IV impact). Use spreads (bull put spread for bullish divergence) to reduce cost. Allow enough time (minimum 2-3x expected holding period to expiration). Example: bullish divergence on daily FTSE 100 - buy a 1-month ATM call or bull call spread (FTSE 100 index options trade on ICE; retail may also use defined-risk spread bets with guaranteed stops).

How do I build a quantitative divergence trading system?

System components: 1) Swing detection algorithm (price pivots with minimum X bars between). 2) RSI calculation at each swing. 3) Divergence detection (compare consecutive same-type swings). 4) Magnitude scoring (angle difference, class A/B/C). 5) Filter criteria (ADX threshold, RSI extreme requirement). 6) Entry logic (confirmation candle, RSI turn). 7) Exit rules (target levels, stops, time exits). Backtesting: test on 3+ years data, minimum 100 trades for significance. Walk-forward validate. Key metrics: win rate 45-55% typical, profit factor 1.4-1.8, max drawdown < 20%. Avoid overfitting by keeping rules simple and testing on multiple instruments. Execution and final trade decisions remain manual and discretionary.

How do divergences relate to Elliott Wave theory?

Elliott Wave integration: Wave 3: strongest wave, divergence rare (momentum strong). Wave 5: final wave, often shows divergence vs wave 3 (momentum weakening). Divergence in wave 5 = wave completion signal, expect correction. Wave B: corrective wave often shows divergence vs prior trend extreme. Wave C: ending diagonal patterns often have divergence at completion. Practical use: if count suggests wave 5 forming, look harder for divergence. Divergence confirms wave exhaustion. Major divergence on weekly/monthly often marks primary wave endings. Caution: wave counts are subjective, use divergence as confirmation rather than sole signal.

What are the mathematical limitations of RSI divergence?

Mathematical limitations: 1) Lookback dependency: RSI value depends on N periods. Different N gives different divergence signals. 2) Smoothing artifact: RSI is bounded 0-100, extreme prices compressed at boundaries. Divergence may reflect compression, not true momentum change. 3) Starting point bias: RSI calculation affected by initial values in lookback window. 4) No statistical edge guarantee: academic studies show mixed results on divergence profitability. 5) Survivorship in examples: memorable divergences that worked, forgetting failures. Mitigation: use multiple confirmation sources, understand divergence as probability enhancement not guarantee, rigorous backtesting before trusting.

How do I evaluate divergence-strategy performance with expectancy and risk of ruin?

Treat it statistically, not anecdotally: 1) Record every trade (setup class A/B/C, timeframe, R-multiple result). 2) Compute win rate (W) and average win/loss expressed in R. 3) Expectancy per trade = (W × avg win R) - ((1 - W) × avg loss R). Example: 45% win rate, +2R winners, -1R losers gives (0.45 × 2) - (0.55 × 1) = 0.90 - 0.55 = +0.35R per trade. 4) Position sizing: risking 1% per trade with +0.35R expectancy compounds slowly but survives variance. 5) Risk of ruin: long losing streaks are normal even with positive expectancy - at a 45% win rate, runs of 6-8 consecutive losses occur, so size such that a streak cannot impair capital. 6) Review monthly: is realised expectancy near your backtest? Has any setup class decayed? Keep the rules fixed and let the sample grow to 100+ trades before judging. This converts divergence trading from opinion into a measurable edge.

How does divergence perform in different market regimes?

Regime performance analysis: Trending regime (ADX > 30): regular divergence often fails or extends. Hidden divergence works well for continuation. Reduce regular divergence trading, focus on hidden. Ranging regime (ADX < 20): regular divergence works well at range extremes. Key reversal indicator in ranges. Increase regular divergence trading. Volatile regime (VFTSE > 25): divergences are clearer (larger swings) but need more confirmation and wider stops. Mixed regime (transition): divergences may signal regime change. Watch for major divergences at regime inflection points. Adaptation: classify current regime first, then select appropriate divergence strategy. Don't use same approach in all regimes.
