Algorithmic Trading Systems & Validation Infrastructure

TTJ Systems Ltd is a UK-based trading technology company focused on building and validating systematic trading strategies for live market conditions.

We develop rule-based trading systems and the infrastructure required to test them realistically — accounting for execution costs, drawdown constraints, and market behaviour that idealised backtests often overlook.

Our work is built for traders and developers who value discipline, transparency, and evidence-driven decision-making.

Rather than chasing perfect historical curves, we design systems and validation workflows that explicitly account for:

• Prop-firm risk rules and drawdown limits
• Execution costs, slippage, and spread variability
• Changing market regimes and performance decay
• The statistical risks of overfitting

Our objective is simple: identify strategies that remain defensible when conditions change.

TTJ Systems Ltd develops rule-based Expert Advisors engineered for controlled deployment, disciplined risk management, and ongoing evaluation within defined frameworks.

We also provide strategy validation infrastructure used to analyse optimisation outputs, filter over-fitted configurations, and compare systems using objective metrics.

Our Expert Advisors are not autonomous profit engines. They are engineered components intended for deployment within clearly defined risk parameters and continuous review.

The validation infrastructure is offered on a rental basis for traders and developers who require repeatable, auditable evaluation workflows.

Trading financial instruments involves risk and may result in the loss of capital.
