CloudStrat v1 – Strategy BuilderBuilt in 2021-2022
CloudStrat Strategy Builder is a visual no-code environment I built for constructing, backtesting, and debugging systematic trading strategies.Strategies are represented as event-driven graphs, where nodes perform computation and edges carry messages between them. Nodes can contain Python or entire nested subgraphs, allowing users to build reusable abstractions, while data-source nodes inject external information such as prices or news. The system expands the graph into an executable simulation and runs it over historical market events.Shown above is the debugger, which can pause a historical simulation at any event so users could inspect the messages, state, and data flowing through the strategy. In the screenshot, it's paused on a very simple trend-following strategy, and is about to inject a price into a comparator block.
