DTrader V3 Adapter

v3-adapter is the integration layer between DTrader V3 and popular strategy frameworks. It packages framework-specific adapters so strategy projects can use DTrader historical market data, real-time quotes, and trading APIs through the framework API they already know.

Current adapter status

Framework	Package / module	Status	What works now	Known gaps
RQAlpha	rqalpha_mod_dtrader	Usable prototype	Daily A-share bars, quote snapshots, RQAlpha mod loading, simulated backtests, guarded paper/live broker bridge	Trading calendar is weekday-only, no futures/options, no tick history, no real exchange holidays, limited live event source
Backtrader	backtrader_dtrader	Prototype	DTrader daily K-lines as Backtrader PandasData, Cerebro smoke tests, guarded broker bridge	No dedicated live event loop, no full Store notification lifecycle, simulated accounting remains Backtrader-side
vn.py / VeighNa	vnpy_dtrader	Prototype	DTrader K-lines as vn.py BarData, quote snapshots as TickData, guarded Gateway buy/sell/cancel bridge	No streaming loop, no full order reconciliation, no CTA engine integration test yet
JoinQuant-style	joinquant_dtrader	Prototype	Local initialize/handle_data runtime, history/get_price/current_data APIs, simulated portfolio, guarded order bridge	Not a full JoinQuant clone; no factor/finance/query APIs, simple instant-fill backtest model
Zipline Reloaded	zipline_dtrader	Prototype	DTrader daily K-lines as Zipline bundle frames, asset metadata, ingest function, csvdir export, fake-writer tests	No minute writer/live broker bridge yet; full exchange calendar/corporate actions need production validation
backtesting.py	backtesting_dtrader	Prototype	DTrader daily K-lines as backtesting.py OHLCV DataFrame, fake Backtest smoke, guarded signal bridge	Single-asset history-first adapter; no full live broker/order reconciliation
vectorbt	vectorbt_dtrader	Prototype	DTrader OHLCV DataFrame/panel loaders, vectorbt Portfolio.from_signals helper, guarded signal bridge	Research/data-first adapter; no full live trading engine/order reconciliation
NautilusTrader	nautilus_dtrader	Prototype	Nautilus-style instrument IDs, DTrader K-lines as staged bar records/catalog CSV, quote snapshot client, guarded execution bridge	Not yet native Nautilus DataClient/ExecutionClient or ParquetDataCatalog writer
QuantConnect LEAN	lean_dtrader	Prototype	LEAN-style symbols, DTrader K-lines as TradeBar/custom-data CSV rows, quote snapshot provider, guarded Brokerage-shaped bridge	Not yet native LEAN IDataProvider/IBrokerage plugin or live deployment package
Other frameworks	TBD	Planned	Article directories and adapter taxonomy exist	Adapter shape not implemented yet

Install as a library

Install the adapter library:

pip install dtrader-v3-adapter

After installation, strategy projects can import the framework module they need, for example rqalpha_mod_dtrader, backtrader_dtrader, zipline_dtrader, backtesting_dtrader, vectorbt_dtrader, nautilus_dtrader, or lean_dtrader.

Optional framework extras:

pip install "dtrader-v3-adapter[backtesting]"
pip install "dtrader-v3-adapter[vectorbt]"
pip install "dtrader-v3-adapter[nautilus]"
pip install "dtrader-v3-adapter[lean]"
pip install "dtrader-v3-adapter[zipline]"

Source setup

Use Python 3.10-3.12. RQAlpha currently runs here with Python 3.11.

uv sync

If you want to run without uv run, activate the venv first:

source .venv/bin/activate

Run against a real DTrader service

Installed package usage:

export DTRADER_BASE_URL="https://your-dtrader-endpoint"
export DTRADER_AUTH="your-auth-token"
rqalpha run --config backtest.yml

Source checkout usage:

PYTHONPATH=src uv run rqalpha run --config configs/backtest.yml

Run without a real DTrader service

Start the mock endpoint in one terminal:

PYTHONPATH=src uv run python scripts/mock_dtrader_server.py

Run an example in another terminal:

DTRADER_BASE_URL=http://127.0.0.1:18080 \
DTRADER_AUTH=dev \
PYTHONPATH=src \
uv run rqalpha run --config configs/backtest_buy_and_hold.yml

Read-only real endpoint validation

Use this before enabling any paper/live order path:

export DTRADER_BASE_URL="https://your-dtrader-endpoint"
export DTRADER_AUTH="your-osk-or-auth-token"
export DTRADER_VALIDATE_SYMBOLS="600519,000001"
PYTHONPATH=src .venv/bin/python scripts/validate_dtrader_readonly.py \
  --output .cache/dtrader-readonly-validation/report.json

This checks quote, kline, account, positions, and orders query APIs. It does not call buy, sell, or cancel endpoints.

Real trading safety

Paper/live configs default to:

enable_trading: false
paper_fill: true

Real DTrader buy / sell calls require both:

mod:
  dtrader:
    enable_trading: true

and:

export DTRADER_ENABLE_TRADING=1

Keep this two-switch guard. Do not enable real trading while validating examples.
