A multidisciplinary analysis staff from the College of Oxford lately developed a GPU-accelerated restrict order e book (LOB) simulator known as JAX-LOB, the primary of its sort.
JAX is a instrument for coaching high-performance machine studying programs developed by Google. Within the context of a LOB simulator, it permits synthetic intelligence (AI) fashions to coach instantly on monetary knowledge.
The Oxford analysis staff created a novel technique by which JAX may very well be used to run a LOB simulator utilizing solely GPUs. Historically, LOB sims are run utilizing pc processing items (CPUs). By operating them instantly on a GPU chain, the place fashionable AI coaching happens, AI fashions are in a position to skip a number of communication steps. In line with the Oxford staff’s pre-print analysis paper, this offers a velocity improve of as much as 7x.
LOB dynamics are among the many most scientifically studied sides of finance. Within the inventory market, for instance, LOBs enable full-time merchants to keep up liquidity all through each day periods. And within the cryptocurrency world, LOBs are embraced at practically each degree by skilled buyers.

Coaching an AI system to grasp LOB dynamics is a troublesome and data-intensive process that, as a result of nature and complexity of the monetary market, depends on simulations. And the extra correct and highly effective the simulations, the extra environment friendly and helpful the fashions educated on them are typically.
In line with the Oxford staff’s paper, discovering methods to optimize this course of is of the utmost significance:
“As a result of their central position within the monetary system, the flexibility to precisely and effectively mannequin LOB dynamics is extraordinarily useful. For instance, it’d enable a monetary firm to supply higher companies or might allow the federal government to foretell the impression of monetary regulation on the steadiness of the monetary system.”
As the primary of its sort, JAX-LOB continues to be in its infancy. The researchers stress the necessity for additional research of their paper, however some consultants are already predicting that it might have a optimistic impression within the fields of AI and fintech.
Jack Clark, co-founder of Anthropic, lately wrote:
“Software program like JAX-LOB is attention-grabbing because it looks as if the precise kind of factor {that a} future highly effective AI might use to conduct its personal monetary experiments.”
