What is Systematic Trading?

Systematic trading uses written, repeatable rules to decide when a market condition should trigger review, an alert, or a trade decision. The rules define inputs, thresholds, timing, and risk limits before results are observed. A systematic process can be manual, coded, or built with a strategy tool. Its defining feature is consistency: the same stated conditions produce the same decision path, subject to the recorded data and assumptions.

Also known as: rule-based trading, systematic strategy, rules-based trading

What makes trading systematic

A systematic trading strategy states the market, inputs, trigger conditions, timing, and risk rules before results are read. The process records rule changes instead of rewriting old evidence.

Testing and monitoring the rule

Use a backtest to replay the rule on historical observations. Check separate periods, trading costs, and relevant market regimes. Live monitoring then applies the frozen rule to new observations.

Stingray helps define, replay, review, and monitor trading strategies. It does not place trades.
