Pairs trading is a market-neutral strategy that simultaneously takes a long position in one asset and a short position in a correlated asset, profiting from the convergence of their relative price spread. By trading the relationship between two assets rather than their absolute direction, pairs trading hedges market risk and generates returns independent of the overall market trend. This approach is widely used by quantitative hedge funds and institutional traders.
Pairs are selected based on statistical cointegration — a long-term equilibrium relationship between two assets. The spread between the pair is calculated and monitored for deviations from its historical mean. Entry occurs when the spread reaches an extreme standard deviation from the mean, anticipating reversion. The trade is market-neutral: long the underperformer and short the outperformer. Correlation versus cointegration: high correlation alone is insufficient — cointegration implies a stable long-term relationship. Risk arises when the fundamental relationship between the pair breaks down permanently.
Enter when the spread between the pair reaches two standard deviations from its historical mean. Go long the underperforming asset and short the outperforming asset simultaneously. Confirm cointegration using statistical tests such as the Augmented Dickey-Fuller test. Use a z-score of the spread to standardise entry and exit thresholds.
Exit when the spread reverts to its historical mean (z-score returns to zero). Stop loss when the spread reaches three or more standard deviations, indicating a potential structural break. Close both legs simultaneously to maintain the hedge. Exit if statistical tests indicate the cointegration relationship has broken down.

Pairs trading requires careful selection of genuinely cointegrated pairs — not just correlated ones. Regularly re-test the statistical relationship as cointegration can deteriorate over time due to fundamental changes. In crypto, common pairs include Bitcoin versus Ethereum, or different exchange tokens within the same sector. Always maintain equal dollar exposure on both legs to preserve market neutrality.
Pullback trading is a trend-following strategy that involves waiting for price to temporarily retrace against the prevailing trend before entering in the trend direction. Rather than chasing breakouts, pullback traders buy the dip in uptrends or sell the rally in downtrends, achieving better entry prices and tighter stop levels. This approach combines patience with trend-following discipline.
Contrarian trading involves taking positions against the prevailing market consensus, buying when fear is extreme and selling when euphoria peaks. This approach exploits the tendency for crowd sentiment to reach unsustainable extremes at market turning points. Contrarian traders use sentiment indicators, positioning data, and extreme technical readings to identify moments when the market is likely to reverse.
Breakout trading involves entering a position when price moves decisively beyond a defined level of support, resistance, or consolidation. The strategy capitalises on the increased momentum and volatility that typically follow the breach of a significant level. The key challenge is distinguishing genuine breakouts from false ones, which requires volume confirmation, context analysis, and disciplined stop placement.
Position trading is a long-term approach where traders hold positions for weeks, months, or even longer to capture major trend moves. Position traders combine higher-timeframe technical analysis with fundamental and macroeconomic factors, entering on significant support levels or trend confirmations and riding trends until the macro thesis changes. This style requires patience and conviction in the face of short-term volatility.
