This endpoint enables:

Time Handling

You must provide exactly one of:

• time → ISO date string (e.g., 2026-02-15T00:00:00Z)
• unix → Unix timestamp in milliseconds

Behavior:

• If openTime ≤ time < closeTime, we return that candle.
• If time is later than available data, we return the most recent OHLCV record.
• If time is earlier than available data, we return the earliest available OHLCV record.
• If no exact match exists, we return the closest available record.

What is OHLCV?

OHLCV stands for:

• Open – Price at the beginning of the candle
• High – Highest price during the interval
• Low – Lowest price during the interval
• Close – Final price of the interval
• Volume – Total traded volume during the interval

OHLCV data is the foundation of:

• Candlestick charts
• Technical indicators (RSI, MACD, Bollinger Bands)
• Quantitative trading models
• Market structure analysis
