How does an AI agent get technical indicators without dumping number walls into context?
It asks for the interpreted state, not a 200-number array. patternfetch returns RSI, EMA and ATR as labels an agent can act on — overbought, above_20_50, a volatility percentage — with the exact numeric value still attached. Cheaper in tokens, and no arithmetic on raw numbers where LLMs hallucinate.
RSIEMAATR (volPct)1m → 1dinterpreted
TL;DR — One POST /v1/brief (or the MCP tool patternfetch_brief) returns interpreted indicator state: RSI as { v, state: overbought | oversold | neutral }, EMA as { v, state: above_20_50 | below_20_50 | mixed | above_20 | below_20 }, and volatility as volPct (ATR as a percentage of price, in the regime block). The agent reads a label, not a 200-number array — and the same call also returns patterns, support/resistance levels, and a one-line nl summary.
Why interpreted, not raw
An LLM reasoning over a long array of indicator numbers does two things badly: it burns tokens carrying the array, and it hallucinates when it tries to compare, average, or cross those numbers. A state label sidesteps both. overbought is cheap to carry and unambiguous to act on; above_20_50 already encodes the moving-average crossover the agent would otherwise have to derive itself. The numeric v is still there for anyone who needs the exact figure — you lose nothing, you just stop paying for arithmetic the model gets wrong. The thresholds and windows are spelled out in the methodology.
