What is a Market Not Held Order
A variation of the market order designed to give the agent greater discretion than a simple market order would allow. “Not held” means that the floor broker is not required to trade at any specific price or in any specific time interval.

A trade with a broker in which the broker commits capital to facilitate the prompt execution of the trader’s order to buy or sell. Often used when order is large / urgent.
R35
What is a Participate (do not initiate) order
A variant of the market-not-held order. The broker is deliberately low-key and waits for and responds to the initiatives of more active traders. Buy-side traders who use this type of order hope to capture a better price in exchange for letting the other side determine the timing of the trade.
R35
What is a Best Efforts order
A type of order that gives the trader’s agent discretion to execute the order only when the agent judges market conditions to be favorable. Some degree of immediacy is implied, but not immediacy at any price.

Markets in which transaction prices are established by public limit orders to buy or sell a security at specified prices. Usually no involvement of market makers and trades are with public investors.

The four components if Implementation Shortfall
- Explicit costs, including commissions, taxes, and fees.
- Realized profit/loss, reflecting the price movement from the decision price (usually taken to be the previous day’s close) to the execution price for the part of the trade executed on the day it is placed.
- Delay costs (slippage), reflecting the change in price (close-to-close price movement) over the day an order is placed when the order is not executed that day; the calculation is based on the amount of the order actually filled subsequently.
- Missed trade opportunity cost (unrealized profit/loss), reflecting the price difference between the trade cancellation price and the original benchmark price based on the amount of the order that was not filled.

Advantages of VWAP
- Easy to compute.
- Easy to understand.
- Can be computed quickly to assist traders during the execution.
- Works best for comparing smaller trades in nontrending markets.
R35
Disadvantages of VWAP
- Does not account for costs of trades delayed or cancelled.
- Becomes misleading when trade is a substantial proportion of trading volume.
- Not sensitive to trade size or market conditions.
- Can be gamed by delaying trades
R35
Advantages of Implementation Shortfall
- Links trading to portfolio manager activity; can relate cost to the value of investment ideas.
- Recognizes the tradeoff between immediacy and price.
- Allows attribution of costs.
- Can be built into portfolio optimizers to reduce turnover and increase realized performance.
- Cannot be gamed.
R35
Disadvantages of Implementation Shortfall
- Requires extensive data collection and interpretation.
- Imposes an unfamiliar evaluation framework on traders.

- Providing other supporting investment services (Prime Brokerage)
- Supporting the Market mechanism

Characteristics of a Liquid Market
- The market has relatively low bid–ask spreads.
- The market is deep. (Big trades do not cause big price movements. High quoted depth)

R35
Factors that make a Market Liquid
- Many buyers and seller
- Diversity of opinion, information, and investment needs among market participants

- Market integrity.
R35
3 Main qualities of a Market

4 Major types of traders
- Information-motivated traders (who trade on information with limited time value. Very short trading time horizons and are more sensitive to time than price in execution)
- Liquidity-motivated traders (who trade based on liquidity needs. Very short trading time horizons and are more sensitive to time than price in execution)
- Value-motivated traders (who trade on valuation judgments. Have longer trading time horizons and are more sensitive to price than time in execution. )
- Passive traders (who trade for indexed portfolios. Have longer trading time horizons and are more sensitive to price than time in execution. )
R35
5 Objectives in Trading
- Liquidity at any cost (I must trade. Often Market Orders)
- Need trustworthy agent (Possible hazardous trading situation. Use a floor broker to skillfully “work” such orders by placing a best efforts, market-not-held, or participate order)
- Costs are not important
- Advertise to draw liquidity (Risk of front running)
- Low cost whatever the liquidity (Often Limit Orders)
