Does one might belief that limit order markets are backed by patient market makers, ready to trade with incoming investors at all times –  reality looks quite different. Liquidity suppliers and traders are restless rather than patient. This way the majority of orders in markets are cancelled or resubmitted with a modified quote before any transactions occurs. In equity markets the top of book quotes of each large - cap US stock is on average updated once every 50 milliseconds, corresponding to six quote updates in the blink of an eye. These short-lived limit orders are also called “fleeting orders”, “flickering quotes” or “phantom liquidity”. The behaviour of submitting and cancelling orders with no intention of execution, with the goal of swaying prices in a favourable direction, a bait-and-switch tactic, is called “spoofing”. Lykke, running a market making trading strategy in cryptocurrencies, wants your help in researching this phenomenon for crypto-markets - to find potential patterns of limit order book submissions and cancellations.


We are interested in research about order book submissions and cancellations in crypto-markets. Can you find any stable patterns?

Limit Order Book

The limit order book is the central structure aggregating the orders of all traders to buy and sell shares of a given stock on an exchange.

The usual economic perspective on a limit order emphasizes its role in supplying liquidity. In this capacity, it is often viewed as extending to the market a visible, ongoing, and persistent option to trade. Unlike a market order, it is passive and patient.

1/3 of all limit orders becomes canceled within 2 seconds! More than 3/4 in only 1 minute. Liquidity provision

Lykke, providing liquidity through its market making trading algorithm, Alpha Engine, has to be aware of other market participants submitting, amending or cancelling their orders in a certain way.

We invite all researchers to familiarise themselves with limit order book research and investigate crypto-markets accordingly. Please do present your findings to us.

Requirements for the work

  • Please present your research about limit order book cancellations, submissions and amendments for crypto-markets in a short document, code, video etc.

  • Any formulas or plots should be also included in the document.


The first 4 contestants will receive a prize money in 400, 300, 300, 300 $.
