Order Strategy, Market Impact, and Execution Quality

1.A portfolio manager sends a large buy with the instruction “work it today.” The stock is thin and no benchmark is specified. What should the trader clarify first?

2.A buy instruction forbids paying more than $24.60. The best offer is $24.62. Which order preserves the instruction?

3.A trader wants immediate execution of whatever is available at or below a buy limit, with no quantity left working. Which time in force fits?

4.A fund must buy a stock at the official closing price for an index rebalance and accepts an unknown price. Which approach best matches the benchmark if venue rules allow it?

5.A closing-auction buyer must pay no more than $37.00. Which order best fits if supported?

6.An order targets the market's VWAP over a full session. Which initial schedule aligns with that objective?

7.A TWAP instruction calls for 96,000 shares over eight equal intervals with no adjustment. What is the quantity per interval?

8.A participation strategy targets 12% of eligible volume measured excluding its own fills. The market prints 250,000 eligible shares over an interval. What quantity does the target imply?

9.A trader must stay at or below 10% participation. The venue counts the trader's fills in total eligible market volume. If everyone else traded 90,000 shares, how many can the trader fill at most?

10.A parent buy is for 75,000 shares. The router has filled 28,000 and has 32,000 working across venues. What new quantity can it send without risking an overfill, assuming every live share can execute?

11.A trader cancels 20,000 shares on Venue A to move them to Venue B. The cancel has not been confirmed. What should the trader count in the parent order?

12.A buyer can post at the midpoint in a venue with uncertain fill probability. The order is urgent and has limited time left. What information most informs the routing choice?

13.A portfolio manager gives an order that is small relative to depth and must be finished immediately. What is a reasonable first check before crossing?

14.A block counterparty offers the full quantity at a modest concession. What comparison is most useful before accepting?

15.A thin stock shows a five-cent spread and a deep queue at the best bid. Your buy has low urgency and is allowed to rest. What is the benefit of improving the bid by one tick, while staying below the offer?

16.A buy order's limit is above the best offer, and the order is eligible for immediate matching. How can it trade?

17.A trader uses a reserve order to display only 2,000 of 20,000 shares. What should the trader verify about the remaining 18,000?

18.A pair trade requires both legs. One security is much harder to trade than the other. What order plan reduces unintended exposure?

19.A trader is asked to execute a stock basket with one missing price limit and several strict limits. What should the trader do with the ambiguous leg?

20.A sell parent is 150,000 shares and needs completion by noon. Expected eligible volume through noon is 600,000 shares. A hard 20% participation cap excludes your own fills from volume. What is the feasibility issue?

21.A venue rejects new orders and you cannot verify whether a recent submission is working. How should you handle that quantity?

22.A stock is halted before your sell completes. The client expects a time-specific hedge reduction. What can the trader do first?

23.A buy has a firm price cap and a hard completion instruction. The market trades above the cap with no eligible liquidity. What should the trader do?

24.A trader needs to sell in size and sees a large displayed bid that has been repeatedly canceled and replaced. What should the plan assume about the bid?

25.A buy order is completed through three brokers, each with discretion to work its slice. What helps prevent the desk from unintentionally becoming more aggressive overall?

26.A manager gives a “not held” order with a hard price ceiling. What discretion does the trader have in this scenario?

27.A trader has 5,000 shares remaining. The minimum order size on a chosen block venue is 10,000. Which action fits the parent instruction?

28.A client wants to buy around the open, but pre-open depth is thin and the opening auction has a participation cutoff. What should the trader compare?

29.A trader wants to reduce visible footprint while retaining a route for a natural block. What arrangement helps control completion and information exposure?

30.A trader must sell 120,000 shares over three intervals. Forecast volume shares are 20%, 30%, and 50%. What is the initial VWAP slice plan?

31.A strategy targets TWAP but the venue is closed for the second of four planned intervals. What is a sensible response?

32.A manager asks for a fixed quantity by close and allows discretion on interim participation. What is the advantage of scheduled checkpoints?

33.A bond order is quoted by multiple dealers. Dealer A's lower offer is for $1 million, while Dealer B can trade the full $5 million at a slightly higher price. What should the trader compare?

34.A client changes a parent order from 100,000 to 60,000 shares after 45,000 have filled and 30,000 remain live. What is the immediate quantity issue?

35.A sell needs to finish by close, but the closing auction is capped at 30,000 shares by the client. There are 55,000 unfilled. How many must be worked outside the auction at minimum for full completion?

36.A client requests price-sensitive buying early and high completion certainty late. What plan captures both objectives?

37.A low-urgency buy is 35% of average daily volume. Depth is shallow and the client permits several days. Which plan best addresses the likely impact?

38.A sell must be completed before a scheduled ruling. Waiting may reduce impact, but the stock could gap down at the announcement. Which exposure favors earlier execution?

39.A trader has a 400,000-share buy and finishes 100,000 before a sudden rally. What quantity is directly exposed to higher purchase prices on the remaining order?

40.A trader can cross now at a 4-cent cost versus midpoint or work the order at a 1-cent expected execution cost plus 5 cents of expected adverse drift. With the same completion and no other differences, which is cheaper in expectation?

41.A patient buy has a 75% chance to save 3 cents relative to immediate execution. If it misses, the trader must pay 11 cents more than immediate execution. What is the expected extra cost of waiting?

42.A low-urgency buy is partway complete when the spread widens and displayed offers thin out. No important event or deadline has changed. Which adjustment directly responds to the conditions?

43.A buy is behind schedule and the stock starts rising with a broad sector rally. Which factor increases the cost of continued waiting?

44.A participation strategy slows as eligible volume drops, and the client has a firm deadline. What should the trader reassess?

45.A model assigns execution cost of 2 cents per share at a 5% participation rate and 5 cents at 15%. For 80,000 shares, what is the modeled extra cost of the faster plan, excluding timing benefits?

46.Two schedules have the same expected cost. One finishes sooner and has a narrower range of arrival-price outcomes. The client prioritizes limiting adverse timing outcomes. Which schedule fits that stated priority?

47.After a sell program stops, the stock rebounds partway toward its earlier level. What is this pattern consistent with?

48.A large buy lifts several offers. How can the trader test whether the observed rise reflects broader market movement as well as the order?

49.A trader has a firm end-of-day sell deadline and sees 60% of forecast volume concentrated at the close. What risk comes from leaving the entire order for the auction?

50.A fund wants to avoid an overnight underweight caused by an unfilled buy. Which trade-off should it consider near the deadline?

51.A broker offers a guaranteed full block 6 cents above arrival. A sliced plan is expected to cost 4 cents but can cost 15 cents in a plausible adverse outcome. What makes the choice defensible?

52.A trader notices aggressive fills cost more per share as child size rises, even at the same quoted spread. What market feature could explain this?

53.A midpoint route has low explicit spread cost but fills mainly when the price is about to move against the order. What should the trader include in venue evaluation?

54.A desk must trade several stocks in one sector after an index change. Each individual order is small, but the basket represents material combined demand. What should the execution plan test?

55.A sell program is half complete when eligible volume for the rest of the day is revised from 800,000 to 500,000 shares. The cap is 15% of eligible volume excluding the trader's fills. How much remaining sell capacity is lost at the forecast?

56.A market maker shows a much deeper offer after a news release, but spreads also widen and quoted size turns over quickly. What should govern a larger buy slice?

57.A trader's plan assumes that a full-session average volume is spread evenly across the day. Actual volume is concentrated at the open and close. What issue can arise at midday?

58.A buy is 90% complete and a scheduled announcement is minutes away. What comparison should determine whether to finish before it?

59.A buy schedule's costs are 2 cents per share in ordinary conditions. In a stress case with half the depth, the same schedule is estimated to cost 7 cents. What should the trader tell the manager?

60.A firm block is quoted for half an order. Accepting it reduces the quantity exposed to future market moves but leaves a residual. What should the remaining plan compare?

61.A trader can slow down to reduce immediate impact, but the investment signal is expected to decay within an hour. What makes a long schedule costly even if prices do not trend during the window?

62.A liquidity event creates unusually deep, firm interest at acceptable prices ahead of schedule. The order is flexible and the trader has a firm completion deadline. What should be reassessed?

63.A buy order has 50,000 shares left at $40. If price rises 2% before they trade, what extra cost would that move alone add relative to buying those shares at $40?

64.A trader prefers passive execution when it is likely to fill. A queue model forecasts lower fill probability as queue-ahead size rises. Which input helps verify that estimate during the order?

65.A client limits a sell's price and participation, but the original deadline becomes harder after a volume shock. What should the trader avoid using as a silent remedy?

66.A trader finds that an order's average cost rises whenever they accelerate after falling behind. What analysis helps distinguish urgency from a causal impact effect?

67.A desk staggers execution in two correlated legs to save spread. What risk should it limit explicitly?

68.A trader must buy 20,000 shares. The offer book shows 5,000 at $50.02, 10,000 at $50.05, and 15,000 at $50.10. What is the average price if all 20,000 execute immediately against this unchanged book?

69.A broker promises low impact based on a 1% participation cap. The order would take four days at that rate and the exposure target is tomorrow. What is missing from the proposal?

70.A trader expects the price impact of a child order to fade before the next interval. What observation would most directly challenge that assumption?

71.A 500,000-share sell has 250,000 remaining. The client will tolerate up to $75,000 of additional cost from adverse movement on that residual. What per-share move uses the full allowance, ignoring fees and nonlinear impact?

72.A seller can complete now at an estimated 9 bp impact cost, or work the order for 4 bp expected impact and tolerate a 12 bp adverse price move in stress. What should the trader present?

73.A trader buys 30,000 shares at $18.04 and 70,000 at $18.10. What is the average fill price before fees?

74.A buy fills 40,000 shares at an average of $25.06 against a $25.00 arrival midpoint. Fees are $320. What is the all-in arrival cost on the filled shares?

75.A trader sells 25,000 shares at $39.90 against a $40.00 arrival benchmark and pays $500 in fees. What is the all-in execution cost on those shares?

76.A buy order averages $50.10 against a $50.00 benchmark. What is the price cost in basis points of benchmark price, ignoring fees?

77.A portfolio decision to buy 100,000 shares was made at $20.00. The order arrived at $20.04 and filled fully at $20.08 before fees. How much of the $8,000 decision-price shortfall occurred before arrival?

78.A buy decision for 80,000 shares is benchmarked at $30.00. The trader fills 60,000 at $30.03 and marks the unfilled 20,000 at $30.15 at the cutoff. Fees are $400. What is implementation shortfall on the whole order under this convention?

79.A client decided to sell 50,000 shares at $16.00. It sells 40,000 at $16.03 and the remaining 10,000 are marked at $15.80 at the cutoff. What is whole-order shortfall before fees, using that mark for the residual?

80.A broker fills 65,000 shares of a 100,000-share buy. The filled average beat VWAP, but the stock rallied after the broker stopped. Which additional measures should the review include?

81.A buyer pays an average of $41.03 during a window whose VWAP is $41.08. Arrival price was $40.90. Which summary is accurate before fees?

82.A market trades 10,000 shares at $10 and 30,000 shares at $10.20 during the eligible window. What is its VWAP?

83.Four equally spaced midpoint observations are $20.00, $20.10, $20.30, and $20.20. If each observation has equal time weight, what is the TWAP benchmark?

84.A close-benchmarked sell executes most shares before the auction. The close rallies above its average sale price. What is the accurate benchmark interpretation?

85.A client gave a ten-minute execution window starting at noon. The broker reports a VWAP comparison against the full day. What should the trader request?

86.A broker's comparison excludes auctions. Another broker includes them. What is needed before comparing VWAP performance?

87.A buy fills at $18.06 while the contemporaneous midpoint is $18.04. Using effective spread defined as twice the signed execution-to-midpoint difference, what is the effective spread per share?

88.A market sell fills at $31.97. The midpoint just before execution is $32.00 and five seconds later it is $31.92. What was the seller's fill price relative to each midpoint?

89.A venue charges lower fees than its peers but produces larger adverse markouts and more missed fills. Which comparison best captures net quality?

90.Venue A receives urgent large orders and Venue B receives small passive orders. Raw costs are worse at Venue A. What comparison would make the ranking more meaningful?

91.A broker shows a 1 bp average cost on completed orders, but frequently cancels orders when the market moves away. What bias should the trader test?

92.A trader buys a stock while its sector rises 3%. The stock rises 3.2% during the order. What can the review conclude about market impact from those two figures alone?

93.A benchmark feed shows the arrival price 20 seconds after the parent was received. Prices moved materially in those seconds. What should the review do?

94.A stock splits two-for-one during a multi-day order. Some early fills are on the old price and share basis. What must the report do before averaging?

95.A parent order was reduced after the investment view changed. Why should the execution report retain the timestamp and reason for the resize?

96.A trader reports the median child-order price to describe a completed parent. Some child fills are tiny and a few are large. Which measure is appropriate for actual average cost?

97.A trader is comparing a quiet day with an event day. On the event day the order beat VWAP but had unusually high arrival cost. What should the commentary explain?

98.A broker shows smaller spread paid after a routing change, but net cost is unchanged. Which bridge would help reconcile this?

99.A TCA model shows 5 bp average shortfall across 1,000 buys, but a few large orders have severe cost. Which breakdown most helps an execution review?

100.Two orders have notionals of $1 million and $9 million. Their costs are 2 bp and 12 bp respectively. What is notional-weighted cost across both?

101.A trader has a favorable five-second markout but a poor 30-minute markout on the same fills. What is the right interpretation?

102.A buyer pays $10.02 at a $10.00 arrival price and later earns a rebate of 0.3 cents per share. What is net cost relative to arrival if there are no other fees?

103.A trade is priced below its arrival benchmark for a buy, but broker fees exceed the price improvement. How should it appear in an all-in report?

104.A broker's post-trade report says a shortfall came from the trader crossing too aggressively. The recorded tape shows most of the move occurred before any order was sent. What should be checked?

105.A buy was worked under a hard ceiling and completed only 80%. Fills beat arrival on average, but the residual closed well above the ceiling. What is a balanced recap?

106.A large sell was worked before a market announcement. It cost 8 bp versus arrival, and the stock fell after completion. How should the trader discuss that outcome?

107.A client asks why a large buy underperformed arrival. Most cost occurred after liquidity disappeared late in the day, when the trader raised urgency to meet the agreed deadline. What answer is most informative?

108.A desk changed its strategy and reports improved arrival cost. Its fill rate fell from 98% to 78% on matched parent orders. What should decide whether quality actually improved?
