# TBarSeries: OHLCV Data Container
| Property | Value |
| ---------------- | -------------------------------- |
| **Category** | Core |
| **Inputs** | OHLCV bar (TBar) |
| **Parameters** | None |
| **Outputs** | Multiple series (Open, High, Low, Close, Volume) |
| **Output range** | Varies (see docs) |
| **Warmup** | 1 bar |
### TL;DR
- `TBarSeries` is a high-performance collection of OHLCV bars.
- No configurable parameters; computation is stateless per bar.
- Output range: Varies (see docs).
- Requires 1 bar of warmup before first valid output (IsHot = true).
- Validated against TA-Lib, Skender, and Tulip reference implementations where available.
## What It Does
`TBarSeries` is a high-performance collection of OHLCV bars. It is the primary data structure for managing historical and real-time market data in QuanTAlib. It uses a **Structure of Arrays (SoA)** layout to optimize memory access and enable efficient SIMD operations across individual price components.
