# pricehub

**pricehub** is a Python package for retrieving OHLC (Open-High-Low-Close) data across various brokers' APIs with a unified interface. 

It supports multiple markets, including spot and futures, and provides flexible timestamp inputs and a wide range of intervals.

Effective trading begins with thorough data analysis, visualization, and backtesting. This package simplifies access to such data, providing a unified solution for retrieving OHLC information across various broker APIs.


## Key Features

- **Unified Interface**: Supports multiple brokers and markets (spot, futures) with a single interface.
- **Flexible Intervals**: Choose from 1 minute to 1 month intervals.
- **Timestamp Flexibility**: Accepts timestamps in various formats (int, float, string, Arrow, pandas, datetime).
- **No Credential Requirement**: Fetch public market data without authentication.
- **Extended Date Ranges**: Unlike official libraries (e.g., Binance), this package imposes no limit on data retrieval (e.g., 200-day limit bypassed).

### Supported Brokers
- Binance Spot
- Binance Futures
- Bybit Spot

### Supported Intervals
- **Minutes**: `1m`, `3m`, `5m`, `15m`, `30m`
- **Hours**: `1h`, `2h`, `4h`, `6h`, `12h`
- **Days**: `1d`, `3d`
- **Weeks**: `1w`
- **Months**: `1M`
