Adds MultiStrategyManager: it runs several strategies concurrently, each with
its own TradingEngine seeded with starting_balance * allocation, so one
strategy's losses cannot eat into another's capital. Weights are normalised
across the run ([1,3] -> 25%/75%). Risk limits stay per strategy (each engine
owns a RiskManager).
New API: POST /api/bot/start-many and GET /api/bot/status. The existing
single-strategy endpoints delegate to the manager, so their behaviour is
unchanged. Adds manager tests (allocation, isolation, duplicate keys) and API
tests.
Phones kept running old JS because their cached index.html pointed at an old
hashed asset. Both images now bake the commit SHA as BUILD_VERSION; the backend
exposes it at GET /api/version and the client reloads once with a cache-busting
query when its own baked version differs. Guarded by sessionStorage so it cannot
loop. /api/version is unauthenticated like /api/health.
Trailing stops: strategies can pass trailing_stop_pct to enter_long/enter_short.
advance_trailing_stop in app/engine/portfolio.py ratchets the stop with the price
(up for longs, down for shorts) and never loosens; the engine persists the
ratcheted level and the backtester applies the same logic. Position gains a
trailing_stop_pct column (additive migration). momentum exposes it as a param.
Parameter sweeps: app/backtest/sweep.py runs a cartesian grid through the same
backtester and ranks by return minus max drawdown. POST /api/sweep plus a
dashboard Parameter sweep panel.
The deploy job hard-failed without CRYPTO_API_TOKEN, and /api/ws (which skips
Basic auth) relied on that token. Drop the requirement: the app now works with
no token at all, matching the backend guard that was always a no-op when unset.
When a token is configured it still protects /api and /api/ws; when it is not,
/api/ws is as open as the rest of the API, which the Traefik Basic auth still
guards for everything else. Adds tests for the tokenless API and WebSocket.
Browsers don't reliably replay Basic-auth credentials on a WebSocket upgrade,
so the dashboard's live feed was stuck on "reconnecting" (only the 5s REST
poll worked). Give /api/ws a higher-priority Traefik router that skips Basic
auth; the backend still requires API_TOKEN, which nginx injects on the
handshake. The deploy now fails closed unless CRYPTO_API_TOKEN is set.
Also: split the nginx /api/ws block so upgrade headers are only set there, and
add reconnect backoff (2s -> 30s) so a failing socket stops hammering.
- RiskManager halts + flattens on max daily loss / drawdown, caps position
size and trades per day; adds a manual kill switch (POST /api/bot/kill).
- Telegram and webhook notifications on trades, errors and halts.
- Optional API bearer token on /api, injected server-side by the frontend
nginx so the browser never sees it.
- Kraken and Coinbase market data (public); Coinbase live broker. Live on an
unsupported exchange now errors instead of silently falling back to paper.
- Strategy presets backed by the StrategyConfig table (CRUD API + UI).
- Idempotent additive-column migration so existing SQLite databases upgrade in
place (fixes the new strategy_configs.name column).
FastAPI backend with a single-strategy async engine, paper and Binance
brokers, pure-python indicators, a backtester that shares the engine's
portfolio math, and a Vue dashboard with a live WebSocket feed. Adds the
Gitea Actions CI/CD workflow that deploys to Traefik via docker_default.
