To apply an event-driven approach to a backtesting system it is necessary to define our components (or objects) that will handle specific tasks: Event- TheEventis the fundamental class unit of the event-driven system. It contains atype(such as "MARKET", "SIGNAL", "ORDER" or "FILL") tha...
Python中的调用flow,基本上可以通过查看一个configure文件得到,以一个两级cache的example系统为例two_level.py (configs\learning_gem5\part1),在python配置文件中声明系统中的关键部件->连接端口->实例化对象(instantiate)->m5.simulation (src\python\m5\simulate.py) -> 此处最终通过_m5.event.simulate(,,) 将...

As will become clear this is precisely what we need in order to carry out high frequency trading simulation. Why event-driven? 1. Code Reuse An event-driven backtester, by design, can be used for both historical backtesting and live trading with minimal switch-out of components. 2. ...
xDEVS stands forA cross-platform (x) Discrete EVent System simulator. This library includes a set of C, C++, C#, Go, Java, Python and Rust repositories that provide an event-driven simulation interface. This interface follows the formalismDiscrete Event System Specification (DEVS). The project ...
In this section, we’ll evaluate the scaling efficacy through a simulation script. Rather than real-world multiple requests being funneled into Amazon SQS from human transactions, we’ll execute a script that injects messages into Amazon SQS, which mimics a real-world sce...

In other words, in event-driven sequential simulation, the time is updated for each event. In general, sequential simulations are deterministic; they easily obey the local causality constraint, and are simple to implement. They have the disadvantage, however, that large discrete event simulations ...

This PR introduces a simple event camera simulation in Python, using numba for performance. The event simulator uses two consecutive RGB images (converted to grayscale), and computes "events" based...
