## Use NOSIBLE when the signal starts before it is an index

Market-moving information does not always begin as a sentiment index. It may start with a regulatory update, regional article, government page, corporate notice, supply-chain warning, or policy document. NOSIBLE is built for that earlier stage: finding the source, verifying when it was available, ranking the event, and making it usable for agents.

## Common MarketPsych comparison questions

### Do we need MarketPsych's ready-made sentiment indices or NOSIBLE's source-level evidence?

NOSIBLE lets teams move beyond a black-box sentiment time series and inspect the evidence behind the signal. It offers ranked events, tickerized multilingual source retrieval, point-in-time replay, and an open-source Qwen3 financial sentiment model, so sentiment can be audited, customized, and linked back to documents, entities, and dates too.

### How important are social-media buzz and author or channel signals to our strategy?

NOSIBLE deliberately avoids making social buzz the center of the product. The advantage is a cleaner, replayable corpus of long-form sources, tickerized events, and entity tags that agents can inspect. For reproducible research, dated documents, multilingual coverage, and source context matter more than author or channel noise or virality.

### Can NOSIBLE replace MarketPsych for currencies, commodities, sovereigns, and crypto sentiment?

NOSIBLE is not a prepackaged cross-asset sentiment index; it is the source and event engine for building one. It gives teams dated documents, multilingual coverage, tickerized events, risk ontologies, and sentiment enrichment, so they can create proprietary signals for currencies, commodities, sovereigns, crypto, or equities with source evidence attached.

### How should we validate MarketPsych's long history against NOSIBLE's point-in-time claims?

NOSIBLE makes validation concrete: what was public, when, where, and under which ticker or entity mapping? Its point-in-time verification and source access let teams test sentiment signals against dated evidence, multilingual coverage, and event replay, rather than trusting a finished series whose construction is hard to inspect or adapt.

### What should an LLM agent do with MarketPsych scores versus NOSIBLE documents?

Use NOSIBLE when the agent must explain itself. It can retrieve sources, apply NOSIBLE's financial sentiment model or other enrichments, cite documents, and reason over event history. A sentiment score can be a feature, but NOSIBLE is the evidence system connecting scores to entities, dates, and sources for decisions.
