Terms of Service
Prismark Systems / Lexicon. Last updated August 2026.
These terms govern your access to and use of the Lexicon Strategy Research Platform (SRP) from Prismark Systems, currently in Private Beta ("the Beta"). By applying for, receiving, or using Beta access, you agree to these terms.
Lexicon is research software only. It is not financial advice, not a trading signal service, not a broker, and not a live execution venue. By using the platform, you acknowledge and accept this.
Access to Lexicon is granted solely at the discretion of the Prismark Systems team. Anyone can create a portal account. Access to Lexicon itself is granted only after manual review and acceptance of a beta application.
You must be at least 18 years old to use Lexicon. It is not intended for, and must not be used by, anyone under that age.
Lexicon is a no-code strategy research platform that lets you define trading setups and test them against historical data.
All outputs from the platform — including trade lists, metrics, equity curves, chart annotations, and analyses — are produced from user-supplied rules and historical data. They are for research review only.
Past performance of a backtested strategy is not indicative of future results. Backtesting is sensitive to rule formulation, data quality, slippage, fees, and market conditions. Any reported results reflect historical scenarios, not live trading.
Trading and investing involve significant risk of loss. You are solely responsible for evaluating whether any setup is appropriate for your own situation. Prismark Systems is not responsible for trading decisions, losses, or outcomes resulting from the use of Lexicon.
While you have Beta access, you agree to the following:
We encourage feedback during the Beta. Your feedback — including bug reports, feature suggestions, and usage notes — helps us improve the product.
By submitting feedback, you grant Prismark Systems a non-exclusive, worldwide, royalty-free licence to use, modify, and incorporate that feedback into the product or our internal processes. We do not claim ownership of your ideas, but we may implement similar functionality independently.
Feedback may be shared internally with the development team. We will not share your feedback publicly without your consent.
The strategies you create on Lexicon are yours. We do not claim ownership of them, and we will not sell them or share them with other users. To operate the platform we need permission to store and process them — to run your tests, show you your own results, and keep your work available when you return. We also retain anonymised records of strategy structure, with any link to you removed, which we use to improve the product and develop new features. These records cannot be traced back to you.
To the fullest extent permitted by law, Prismark Systems, its team members, and affiliates are not liable for:
These terms are governed by the laws of the State of Florida, United States, and any dispute arising from them will be handled by the courts of that state. If you are a consumer resident in the United Kingdom or the European Union, this does not remove the protections available to you under the law of the country where you live, and you may bring proceedings there.
We may update these terms as the product and Beta programme evolve. Material changes will be communicated to active beta participants. Your continued use of the platform after changes are posted constitutes acceptance of the updated terms.
