Order Slicing Schedule
An order slicing schedule is the time-based plan an execution algorithm follows to release child orders, defining how a parent order's volume is distributed across the trading window.
A TWAP schedule distributes child orders evenly over time, while a VWAP schedule front- and back-loads them to match the expected U-shaped intraday volume curve of Indian equities. The schedule encodes the algo's trade-off between completing on time and minimising market impact.
Static schedules are predictable and can be anticipated by other participants, so adaptive algos deviate from the planned schedule in response to real-time liquidity and price moves. The schedule is the backbone of slicing, with participation-based algos like POV replacing a fixed clock with a volume-tracking rule.

- Execution AlgorithmAn execution algorithm is a program that works a large parent order into many smaller child orders over time to minimise market impact and achieve a target benchmark such as VWAP or the arrival price.
- TWAP (Time Weighted Average Price)TWAP is an execution strategy and benchmark that spreads an order evenly across a chosen time window, aiming to trade at the average price over that period regardless of volume distribution.
- VWAP (Volume Weighted Average Price)VWAP is the average price of a security over a period weighted by traded volume, used both as an execution benchmark and as the target for an algorithm that trades in proportion to historical volume.
- Slicing (Order)Slicing is the breaking of a large parent order into many smaller child orders released over time, the core technique by which execution algorithms reduce market impact and conceal size.
