Pairs Trading Execution
Pairs trading execution is the practical application of taking simultaneous long and short positions in two correlated assets to profit from a relative price movement. The execution phase involves identifying a spread, determining the entry threshold based on statistical significance, and managing the trade as the spread converges.
Traders must account for transaction costs, borrow fees for shorting, and the risk of the correlation breaking down entirely. Efficient execution often requires algorithmic tools that can monitor multiple order books simultaneously and place trades with minimal slippage.
Because the profit margins on these trades are often thin, precision in timing and cost control is essential. Proper risk management during execution includes setting clear stop-loss levels for the spread itself, ensuring that a temporary divergence does not turn into a permanent loss.
