trainoo market data

Public mirror of the trainoo market-data lake. One repository holds every provider and symbol; the lake-relative path selects a slice (provider={P}/symbol={S}).

Layout

kind	path
ticks	normalized/ticks/provider={P}/symbol={S}/year=YYYY/month=MM/part-00000.parquet
bars	bars/{tf}/provider={P}/symbol={S}/year=YYYY/month=MM/part-00000.parquet

Timeframes: 1s, 30s, 1m, 2m, 3m, 5m, 6m, 10m, 15m, 30m, 45m, 1h, 2h, 3h, 4h, 6h, 8h, 12h, 1d, 1w.

Schema

• ticks: ts_ns (int64 UTC ns), price, qty, is_buyer_maker.
• bars: open_ts_ns (int64 UTC ns), open, high, low, close, volume, buy_volume.

Conventions

• All timestamps are UTC ts_ns (int64 nanoseconds since the Unix epoch).
• Ticks are the raw Binance aggTrades: multiple rows per millisecond are expected and preserved (not de-duplicated on time).
• Bars are half-open [open_ts_ns, close_ts_ns); one part per calendar month.
• Data is feed-specific: it is never merged across providers.

Reading a slice

from huggingface_hub import snapshot_download, hf_hub_download

repo = "mihailnica1000000/trainoo"
# a whole provider/symbol slice (ticks + every bar timeframe)
snapshot_download(
    repo_id=repo,
    repo_type="dataset",
    allow_patterns=["normalized/ticks/provider=binance_um/symbol=BTCUSDT/**",
                    "bars/*/provider=binance_um/symbol=BTCUSDT/**"],
)
# or a single month part
path = hf_hub_download(
    repo_id=repo,
    repo_type="dataset",
    filename="normalized/ticks/provider=binance_um/symbol=BTCUSDT/year=2024/month=01/part-00000.parquet",
)
