Usage

Basic Example

import logging
from datetime import datetime, timezone
from lotech_market_data import LotechMarketData

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

client = LotechMarketData()

# Get time range for today
query_date = datetime.now(timezone.utc).date()
start = datetime.combine(query_date, datetime.min.time()).replace(tzinfo=timezone.utc)
end = datetime.combine(query_date, datetime.max.time()).replace(tzinfo=timezone.utc)

# Fetch top of book data
df = client.load_top_of_book(
    exchange="BINANCE",
    instrument="BTC-USDT:SPOT",
    start=start,
    end=end,
)

logger.info("Total rows: %d", df.height)

API Methods

The LotechMarketData class provides the following methods:

Market Data Methods

All market data methods accept the following parameters:

• exchange: Single exchange string or list of exchanges (e.g., "BINANCE" or ["BINANCE", "BYBIT"])
• instrument: Single instrument or list (e.g., "BTC-USDT:SPOT" or ["BTC-USDT:SPOT", "ETH-USDT:SPOT"])
• start: Start datetime (timezone-aware)
• end: End datetime (timezone-aware)
• columns (optional): List of columns to return

Available methods:

• load_top_of_book() - Top of book (bid/ask) data
• load_trades() - Trade data
• load_funding() - Funding rate data
• load_reference_price() - Reference price data
• load_open_interest() - Open interest data
• load_orderbook_incremental() - Incremental orderbook updates

Instrument Static

# Get all instruments for an exchange (latest)
df = client.load_instr_static(exchange="BINANCE")

# Get all instruments at a specific datetime
df = client.load_instr_static(
    exchange="BINANCE",
    datetime=some_datetime
)

# Filter for specific instrument(s)
df = client.load_instr_static(
    exchange="BINANCE",
    instrument="BTC-USDT:SPOT"
)

df = client.load_instr_static(
    exchange="BINANCE",
    instrument=["BTC-USDT:SPOT", "ETH-USDT:SPOT"]
)

Column Filtering

You can filter columns to reduce data transfer:

df = client.load_top_of_book(
    exchange="BINANCE",
    instrument="BTC-USDT:SPOT",
    start=start,
    end=end,
    columns=["exchange", "instrument", "ingress_ts", "bid_price", "ask_price"],
)

Multiple Exchanges

Query multiple exchanges:

df = client.load_top_of_book(
    exchange=["BINANCE", "BYBIT"],
    instrument="BTC-USDT:SPOT",
    start=start,
    end=end,
)

Multiple Instruments

Query multiple instruments:

df = client.load_top_of_book(
    exchange="BINANCE",
    instrument=["BTC-USDT:SPOT", "ETH-USDT:SPOT", "SOL-USDT:SPOT"],
    start=start,
    end=end,
)

Available Exchanges

Get the list of available exchanges programmatically:

exchanges = LotechMarketData.get_available_exchanges()
logger.info("Available exchanges: %s", exchanges)

Current exchanges include:

• BINANCE
• BITFINEX
• BITGET
• BITMART
• BITMEX
• BITRUE
