Simulation Market maker - Spread   SC_EZP1_US_V6

Simulation scenario

In this simulation you will discover the market making activity. As a market maker, you will participate to the market for EasyPlane stocks (ticker symbol: EZP).

Your goal is to maximize your trading gain.

At the start of the simulation, you own an account worth 20,000 in cash.

In this simulation, you can buy or sell stocks on credit in order to take larger positions than in the spot position. To compute your available hedge to buy and sell stocks on credit, cash benefits from a leverage rate of 5 and stocks from a leverage rate of 2.5.

Financial leverage effect (use of credit) amplifies the variations of market prices on your position (the increase in risk comes along with the desired increase in expected return). Note that in case of exceeding of your available hedge following an adverse evolution of the stock price, your position will be automatically cut by the market system.

The duration of the simulation is initially set to 10 minutes, which corresponds to a 24-hour day. Using the TimeLine, you can increase or decrease the simulation speed at any time.

You can relaunch the simulation as many times as you wish.


Your grade for this simulation (100 points) takes into account the following elements:

  • Your trading performance (70 points): your relative performance, that is to say the difference between your gain/loss on your position with your intervention during the simulation and the gain/loss without your intervention (as if you haven't sent any order). A relative performance between 0 € and 10 000 € is expected. ☛ Computation of the points of performance

  • Your trading activity (15 points): the launching of the simulation (5 points), your determination to go to the end of the simulation (5 points) and the sending of at least one order to the market (5 points)

  • Your grade in the MCQ test at the end of simulation (15 points): 3 questions about the simulation (5 points by question).

If you launch the simulation several times, the simulation grade retained is the best grade you obtained on all the simulations (grade which takes into account your trading performance, your trading activity and your MCQ test for each simulation).


EasyPlane is a low cost airline company. Founded at the beginning of 2010, EasyPlane mainly serves big European capitals with some flights towards the United States and Asia as well.

As its name suggests, EasyPlanes goal was to make it easy for passengers to take a flight. For this, EasyPlane uses new technologies to automate all the process: from ticket purchase (website and mobile app) via boarding (triple recognition of the person based on fingerprints, face and voice, visual and sensory scanning of the luggage) up until the actual flight (online ordering of drinks or meals and service provided by robots). Even the airplane is piloted remotely with an expert system helping the only pilot in the cabin.

For the firm, this innovative approach allowed to have much lower operating costs compared to those faced by the competitors still improving passengers safety. This approach attracted the Z generation formed by young people who were born in the era of new technologies, always connected and who do not have the time to lose their time.

Evolution of the stock price

The ticker symbol of EasyPlane is EZP.

Privately held for a long time and very well valued by the funds that believed in this project from the beginning, the unicorn EasyPlane publicly entered the market only two years ago. The stock price took off phenomenally right after the quotation: started off with a price equal to €45, some months afterwards the stock price got already multiplied by 5! In order to make the price more attractive for the investors, recently the firm had to divide by 20 the value of its stocks (stock split).

EasyPlane is followed by around 15 financial analysts. In particular, market participants are very much looking forward to the recommendations coming from Marina Boat and Douglas Flint, and their recommendations (not always concordant) often have a significant impact on the price of EZP stocks.

Since several weeks, the stock price of EZP has experienced some ups and downs, and ranges around €10.

What will happen today...

Today, the stock price of EasyPlane should evolve according to the information flow arriving to the market (news flow) and to the demand for the stock.

Today it may be a particularly calm day: no expected diffusion of economic indicators, no scheduled announcement from the firm... but who knows?
