What is technical analysis and does it work? Which indicators matter? Clear answers on strategy, backtesting, and chart analysis.

Strategy and technical analysis represent the part of trading that most people spend the most time on, and, frequently, where the real gaps in performance sit. The challenge isn't usually that a trader doesn't know what a moving average is or what a head-and-shoulders pattern looks like. It's that they haven't built a strategy with genuinely defined entry criteria, a tested edge, and position sizing rules that survive a losing streak without depleting their capital.
Technical analysis is a lens for interpreting price behaviour, not a prediction machine. The same indicator produces different outcomes in different market conditions, which is why traders who memorise patterns without understanding the underlying market structure they're supposed to reflect tend to plateau at the same level of inconsistency. The questions in this section are written for traders who have moved past the basics and are working through the harder problems: how to develop a strategy that holds up across different market conditions, how to evaluate whether an edge is real or a product of selective memory, and how to execute consistently when the market is actively testing your discipline.
For South African traders, there are specific timing and instrument considerations that shape which strategies are practical. The London-New York session overlap from approximately 15:00 to 17:00 SAST offers the most reliable liquidity on major forex pairs. The rand's known sensitivity to domestic political and economic events creates recurring volatility patterns on USD/ZAR that differ from the relatively smooth trending behaviour of major cross-currency pairs.
Technical analysis studies price charts to predict future movement.
Moving averages, RSI, and MACD are among the most commonly used indicators.
Fundamental analysis studies economic data and value; technical analysis studies price charts and patterns.
Support and resistance are price levels where buying or selling pressure has historically paused or reversed movement.
Candlestick patterns visually summarise price action over a period, with some patterns showing modest statistical edge.
Leading indicators attempt to predict future price movement, while lagging indicators confirm trends already underway, each with distinct trade-offs..
Price action trading analyses raw price movement and chart patterns directly, without relying primarily on calculated technical indicators for decision-making..
A trading strategy is a defined set of rules for entries, exits, and risk management.
A trading plan covers your broader goals, capital, and rules, while a strategy is the specific entry and exit logic within that plan.
A trading edge is a demonstrable, statistical tendency for your strategy to profit over a large sample of trades.
A trading system is the complete, precisely defined set of rules covering entry, exit, and money management, often implying greater mechanical rigidity than a strategy..
A trading checklist formalises your strategy's entry criteria into a step-by-step list, reducing the chance of impulsive trades that skip important steps..
A trading playbook documents your specific, recognised setups with predetermined entry, exit, and risk criteria for each, supporting consistent execution..
A trading thesis articulates your specific reasoning for a trade in writing, supporting clearer analysis and more honest post-trade review of your decisions..
Backtesting tests a strategy against historical price data before risking real money.
Overfitting occurs when a strategy is excessively tuned to historical data, performing impressively in backtests but poorly on genuinely new, unseen data..
Walk-forward testing validates a strategy on data sequentially after optimisation, providing a more realistic check against overfitting than backtesting alone..
This test deliberately introduces small parameter changes to check how sensitive a strategy's results are, revealing genuine robustness versus fragile overfitting..
Edge decay occurs when a previously profitable strategy gradually stops working as market conditions evolve, distinct from normal short-term statistical variance..
MACD tracks the relationship between two moving averages to gauge momentum.
Moving average crossover signals widely watched as indicators of major trend shifts.
RSI measures the speed and magnitude of recent price moves to identify overbought and oversold conditions.
Round numbers attract outsized market attention. Why psychological levels matter for USD/ZAR right now.
Fibonacci retracement levels identify potential support and resistance based on mathematical ratios, widely used though with the same mixed evidence as other tools..
Divergence occurs when price and an indicator move in opposite directions, sometimes signalling weakening momentum and a potential upcoming reversal..
A genuine breakout sustains momentum beyond a key level, while a fakeout briefly breaches the level before reversing, often trapping early entrants..
A breakout filter adds confirming criteria like volume or candle close requirements, reducing exposure to the fakeouts discussed elsewhere at the cost of speed..
Elliott Wave Theory proposes markets move in repeating wave patterns, a genuinely complex, subjective framework with mixed evidence supporting its predictive reliability..
The Ichimoku Cloud combines several components into one indicator showing trend, momentum, and support and resistance, though it has a genuine learning curve..
A trend line connects price points along one direction, while a channel adds a second, parallel line creating bounded zones traders watch for entries and exits..
Algo trading uses coded rules to trade automatically. Learn about EAs, trading bots, AI trading, VPS and load shedding for SA traders.
Yes, multi-timeframe analysis combines the broader context of higher timeframes with the precision of lower ones for more informed trading decisions..
Confluence occurs when signals from different timeframes align, providing stronger confirmation than any single timeframe's signal considered in isolation..
Trend-following bets on continuation of existing price direction, while mean reversion bets on price returning toward an average after becoming overextended..
Systematic trading follows precisely defined, mechanical rules, while discretionary trading involves human judgement applied within a broader framework..
News trading specifically targets price movement around scheduled announcements, requiring different skills and risk management than chart-based technical trading..
Leading economic indicators anticipate future activity while coincident indicators reflect current conditions, complementing the technical indicator distinction discussed elsewhere..
A trailing stop-loss automatically follows price in your favour, locking in gains as trends extend.
Win rate measures the percentage of profitable trades, but matters only in combination with risk-reward ratio for genuinely assessing overall profitability..
Predetermined partial-exit rules or trailing stop adjustments support disciplined early profit-taking without abandoning your original strategy criteria reactively..
