Execution Algorithm

An execution algorithm is a pre-programmed set of automated instructions used to break down and execute large orders in the market in a systematic, rules-based manner — minimising market impact, reducing transaction costs, and optimising fill quality. Common execution algorithms include VWAP (executes in proportion to historical volume patterns), TWAP (executes at equal intervals over time), Implementation Shortfall (balances market impact against timing risk), and Arrival Price. In India, algorithmic trading accounts for a significant and growing proportion of exchange volumes on NSE and BSE. Institutional investors, mutual funds, and proprietary trading desks use execution algorithms as a standard practice for deploying large capital efficiently without moving the market against themselves.
