## When to prefer this

Use this endpoint when you need the full longitudinal time series of Stock Trends indicator values for a symbol — ideal for backtesting, charting trend evolution, studying persistence and maturity dynamics, or building features for a model. Prefer this over the snapshot endpoint when historical context or trend sequencing is required.

## Known failure modes

- Missing or malformed symbol_exchange parameter (must match pattern ^[A-Z0-9.]+-[A-Z]$) returns a 400 error
- Invalid exchange code not in enum [N,Q,A,B,T,I] returns a 400 validation error
- Symbol not found or not covered by Stock Trends returns empty results or 404
- Date range with no available data returns empty array
- Limit exceeding maximum of 2600 returns a 400 error
- Payment not provided or invalid x402 payment returns 402 Payment Required

## How this service works

Historical weekly Stock Trends indicator series for a symbol. Stock Trends indicators are part of a multi-decade classification framework with records extending back to 1980. Their value comes from consistent semantics across market history: trend state, trend persistence, relative performance, relative performance direction, and volume activity are encoded in a stable doctrine designed for longitudinal research.

## Output

A JSON array of weekly records for the requested symbol, each containing: trend classification code, trend_cnt (consecutive weeks in trend), mt_cnt (maturity count), RSI value, rsi_updn direction flag, vol_tag (volume activity tag), price-change metrics, moving average values, and weekly high/low context. Records span the requested date range up to the specified limit.
