Indicators
Define the setup, not just the trigger
Use indicators, comparators, and rule logic to express what the trader is actually looking for.

LEXICON // STRATEGY RESEARCH PLATFORM
Backtest the trading setup you actually see on the chart.
Lexicon is the Strategy Research Platform (SRP) from Prismark Systems, powered by a Quant Definition Language (QDL). Define the setup with indicators, anchors, timing, sequence, and persistence. Run the historical test. Review the research.
Lexicon is for traders who need to test the full setup as research — not just a simplified trigger.
Private Beta. Research software only. Not signals, advice, or a profit system.

Product mechanism
From chart idea to structured research.
Lexicon, the Strategy Research Platform (SRP) from Prismark Systems, helps traders define the setup, run the historical test, and review the research without trying to explain every edge case on the homepage.
The setup can be expressed as indicators, anchors, timing, sequence, and persistence rather than one isolated trigger.

PROBLEM AND DIFFERENTIATION
The problem is not having a backtester. The problem is testing the full setup.
Many traders think in setups: context develops, confirmation follows, timing matters, and the idea is invalid if the market behaves differently. Ordinary tools often compress that into a simpler signal test.
Where ordinary tools usually break down
- Strong for simple triggers, weaker for multi-step setup logic
- Timing between events is difficult to express cleanly
- Context often gets reduced to one static filter
- Invalidation rules become hard to model clearly
- Cross-market confirmation rarely sits inside one coherent definition
Ordinary backtestersLimited
- Start with a trigger or signal
- Simplify the setup into isolated rules
- Ask: did the signal fire?

Beta language surface summary
A concise public summary of what the Beta is being built to express.
For fuller detail, the deeper language pages cover supported indicators, anchors, comparators, methodology, and limitations.
Anchors and timingCONTEXT
Keep context inside the definition
Use anchors (like PRIOR_DAY_HIGH or OPENING_RANGE), custom time-buckets, and persistence so context is not reduced to one static filter.
SequenceORDERED
Model what happens first and what confirms next
Shaped around sequences, timing, and must-hold conditions instead of isolated signals.
Reviewable researchRESEARCH
Inspect the output as research
Run the historical test, review the output, and refine the setup without implying live-trading certainty.
Illustrative example structures
Two concise examples of how a setup can be expressed.
These examples are here to show structure only. Deeper explanation lives on the language and methodology pages.
Examples are illustrative target Beta rule structures, not trading recommendations.
