Check out the new article: Neural Networks in Trading: A Spiking Architecture for Spatio-Temporal Market Analysis (SDformerFlow).

The article presents an adaptation of the SDformerFlow spiking architecture for the task of dense analysis of price micro-movements. The spatio-temporal structure provides a high level of detail, while the spiking logic ensures computational efficiency and the ability to work with sparse, pulse-like data. As a result, traders gain access to a tool that detects even the slightest shifts in liquidity and provides the foundation for more accurate and consistent real-time decisions.

Event-based approaches offer a different perspective. They respond not to time itself, but to the occurrence of changes. This is particularly natural for the market. After all, every tick is an event. Every surge in liquidity is a signal. Every micro-pause is part of the bigger picture. The SDformerFlow architecture is based precisely on this principle. It does not wait for the next uniform frame, but starts working the moment the market actually changes. This event-driven logic brings the model closer to the very nature of market data, in which value lies not so much in the values themselves as in the moments when they change.

The initial ideas for this approach came from the field of computer vision, where event cameras recorded not static frames, but only changes in brightness at each point. If we apply this logic to finance, it becomes clear just how similar the two worlds are. Tick data is likewise a sparse stream of events. What matters to us is the dynamic relationship between adjacent values, not just the fact that they exist. Therefore, the application of event-driven architectures to trading appears to be a natural evolution of analytical methods.

SDformerFlow has a number of features that make it particularly well-suited for analyzing market microstructure. Spiking dynamics allow the system to respond to sudden changes in a natural and efficient manner, keeping the model's attention focused on the most significant events. The window-based attention mechanism makes it possible to capture local relationships while also grasping the overall pattern of movement. The model does not impose an artificial rhythm on the market, but rather adapts to its natural rhythm. This makes it possible to detect subtle shifts in liquidity and reconstruct the hidden rate of price change.

The deeper we delve into the fabric of market movements, the more obvious it becomes that traditional methods are losing touch with reality. Between two consecutive ticks, an entire miniature battle over liquidity can unfold: a limit order is removed and reappears, and incoming orders arrive at an increasing rate. On a conventional chart, all of this disappears, reduced to a single value. Event-driven architecture fills this gap and allows us to see the market structure between the lines. Where the precursors of movement are born, before they have taken on a visual form.
