  • ✓Setting a bid-ask spread that reflects your uncertainty
  • ✓Updating quotes after a fill (adverse selection - the person who traded knows something)
  • ✓Inventory management: skewing quotes to flatten a position
  • ✓Hedging exposure instead of letting it build

What it tests, with a worked example

Every example below is generated by Outcry, drawn from the same question generators the timed drills run. None of them is Wincent’s.

Quoting a two-sided market

A bid and an ask around a fair value, wide enough to survive being wrong.

Example

HOW IT SCORES
One of the 13 rows is drawn at random as the winning row. Every
row is equally likely. A letter scores its own row number minus
the winning row number, and a wager pays that score in dollars
per unit.

ROW      LEFT   RIGHT
---------------------
  1      Z      A
  2      K      Y
  3      T      J
  4      B      S
  5      L      D
  6      I      Q
  7      P      U
  8      G      E
  9      X      N
 10      F      W
 11      V      O
 12      M      H
 13      R      C

A market maker shows minus 10.5 bid, minus 7.5 offered on K. What is the best edge available to you, in dollars a unit?

Answer 2.5

K is worth -5. The offer of minus 7.5 is below that, so you buy and collect -5 - -7.5 = 2.5.

Pricing under partial information

Half the board is hidden, and the quote has to price what you cannot see.

Example 1

HOW IT SCORES
One of the 13 rows is drawn at random as the winning row. Every
row is equally likely. A letter scores its own row number minus
the winning row number, and a wager pays that score in dollars
per unit.

ROW      LEFT   RIGHT
---------------------
  1      N      A
  2      Y      Q
  3      V      T
  4      I      W
  5      R      X
  6      D      Z
  7      E      U
  8      H      O
  9      C      M
 10      J      P
 11      L      G
 12      K      B
 13      F      S

The board is written in a cipher. Every letter shown is the letter
3 places later in the alphabet than the real one, wrapping from Z to A.

What is one unit of a wager on D worth, in dollars?

Answer 4

D is written as G on the board, and G is in row 11. The wager is worth 11 - 7 = 4.

Example 2

HOW IT SCORES
One of the 13 rows is drawn at random as the winning row. Every
row is equally likely. A letter scores its own row number minus
the winning row number, and a wager pays that score in dollars
per unit.

 13      G      X

Rows 5 to 8 are face down. Between them they hold
H, J, L, N, P, U, V, Z, but not in any stated order.

You hold 20 units of Z. What is the worst the position can score, in dollars?

Answer -160

The worst case stacks both unknowns against you: Z in row 5, the highest of the face-down rows, and row 13 winning. That is 5 - 13 = -8 a unit, or -160 over 20.

Example 3

HOW IT SCORES
One of the 13 rows is drawn at random as the winning row. Every
row is equally likely. A letter scores its own row number minus
the winning row number, and a wager pays that score in dollars
per unit.

ROW      LEFT   RIGHT
---------------------
  1      P      F
  2      B      D
  3      X      U
  4      I      Z
  5      Q      M
  6      A      E
  7      Y      G
  8      T      V
  9      C      H
 10      N      J
 11      ?      ?
 12      ?      ?
 13      ?      ?

Rows 11 to 13 are face down. Between them they hold
K, L, O, R, S, W, but not in any stated order.

What is the probability a wager on W scores above zero? Answer as a percentage.

Answer 84.6

From row r the chance is (r - 1) ÷ 13. Averaging r over rows 11 to 13 gives 12, so the answer is (12 - 1) ÷ 13 = 84.6%.

Adverse selection

Whoever trades with you may know something. Size and spread are the defence.

Example

HOW IT SCORES
One of the 13 rows is drawn at random as the winning row. Every
row is equally likely. A letter scores its own row number minus
the winning row number, and a wager pays that score in dollars
per unit.

ROW      LEFT   RIGHT
---------------------
  1      H      G
  2      L      P
  3      I      O
  4      C      Y
  5      Z      U
  6      E      W
  7      Q      N
  8      S      D
  9      X      B
 10      J      A
 11      F      R
 12      T      K
 13      V      M

You are long 20 units of Q and short 20 units of J. What does the combined position score, whichever row wins, in dollars?

Answer -60

The winning row cancels between the two legs: 20 × ((7 - W) - (10 - W)) = 20 × -3 = -60, for every W. Matching size on two letters turns a bet on the draw into a fixed amount.

Option mechanics

Payoffs, parity and moneyness, at the speed a trading floor asks them.

Example

You sell the $80 put at $8.40 and buy the $60 put at $2.40, same expiry. What is the most this can lose, per share?

Answer 14

The credit taken in is $8.40 - $2.40 = $6.00, which is the best case. The worst case is the stock below 60, where the 20 point gap is owed in full: 20 - $6.00 = $14.00. A credit spread collects a little often and pays out a lot rarely - the strike gap bounds the damage, which is the only reason it is sellable.

The Greeks

Delta, gamma, vega and theta as directions rather than formulas.

Example

You are long 20 of the $60 calls at delta 0.42, short 50 of the $70 puts at delta -0.25, and short 500 shares. Contracts are on 100 shares each. What is the book's net delta, in shares?

Answer 1590

Long calls: 20 x 100 x 0.42 = 840. Short puts: -50 x 100 x (-0.25) = +1250, because shorting a negative delta is long delta. Short stock: -500. Net = 840 + 1250 - 500 = 1590 shares. The sign on the short put leg is where books get added up wrong.

Sizing the trade

How much to do at your own price, which is a different question from what the price is.

Example

HOW IT SCORES
One of the 13 rows is drawn at random as the winning row. Every
row is equally likely. A letter scores its own row number minus
the winning row number, and a wager pays that score in dollars
per unit.

ROW      LEFT   RIGHT
---------------------
  1      M      Z
  2      A      K
  3      L      Y
  4      C      Q
  5      O      R
  6      G      F
  7      E      N
  8      D      S
  9      I      P
 10      X      J
 11      H      V
 12      W      T
 13      B      U

A single-letter wager carries 3.74 dollars of standard deviation
per unit, because the winning row is uniform on 1 to 13.

Your sizing rule is edge divided by variance, times bankroll. The variance of one unit is 14. With a bankroll of $7000, how many dollars do you put on T at 2?

Answer 1500

T is worth 5 and costs 2, so the edge is 3. 7000 × 3 ÷ 14 = 1500. Double the edge and you double the size, double the variance and you halve it.

What a good score looks like

No current employer cutoff is verified for these general practice ranges. Use the worked examples to identify what to study and check your role-specific invitation for the actual assessment rules.

How to train for it

  1. 01Get fast on fair value first. You cannot quote around a number you are still computing.
  2. 02Practise saying the spread out loud with a reason attached. Width without a reason reads as guessing.
  3. 03Play a round where you get filled and have to re-quote. The update is what the round is actually testing.
