Changelog

GET /api/v1/datafeed/history now answers {"s":"error","errmsg":"history temporarily unavailable"} when the venue fetch fails, for example during a rate limit. It used to answer {"s":"no_data"}, which looked like a market with no candles. The status code stays 200. no_data now only means there are no candles in the range, so retry on error.

GET /api/v1/markets accepts sortBy=gainers and sortBy=losers: only rising or falling markets, biggest move first, with total as the filtered count. POST /api/v1/emitters/summary accepts sortBy=lowDrawdown and freeOnly (public lists only). POST /api/v1/automations/summary accepts sortBy=todayPnl, and total now counts every matching automation instead of stopping at offset + limit per type.

Pass benchmark=async to GET /api/v1/me/statistics/by-tag to get each tag’s statistics right away instead of waiting for account buy-and-hold on a cache miss. benchmark_history can then be empty for a tag until the series is ready. Without the param, behavior is unchanged.

Account buy-and-hold (benchmarkHistory) is now cached server-side until the next UTC midnight, and it is recomputed the same day when the running count, total capital or first PnL day changes. Pass benchmark=async to GET /api/v1/me/statistics to get an answer right away: while the series is still computing, the response has benchmarkPending: true and an empty benchmarkHistory. Poll until it is false. Without the parameter the call waits for the series as before. MCP get_user_statistics uses the same cache.

• POST /api/v1/exchange/leverage and set_exchange_leverage now work on all terminal perp venues (Aster, Binance USDⓈ-M / COIN-M, Bybit, OKX, Bitget, Kraken Futures, Hyperliquid, Lighter) and accept an optional margin_mode (crossed | isolated).
• POST /api/v1/exchange/margin-mode and set_exchange_margin_mode switch cross/isolated margin. The response scope says whether the venue applied it per symbol, account-wide, or together with leverage. OKX has no such API.
• GET /api/v1/exchange/leverage-capabilities and get_exchange_leverage_capabilities return a static per-venue support matrix (no venue call).

GET /api/v1/markets, MCP list_markets, and SDK/CLI get-markets include optional logo_url from asset_profiles for each row (empty when unset).

GET /api/v1/markets?sortBy=abs_change ranks by absolute 24h change. POST /api/v1/automations/status-counts and POST /api/v1/automations/summary/by-ids support Bots chips and batch favorites (read:automations).

POST /api/v1/followers and MCP create_automation (type follower) accept optional loss_limit_pct (0–100). When set, order-executor blocks new risk after total PnL reaches −pct% of initial_capital until the follower is restarted. Stored as params.lossLimitPct.

GET /api/v1/backtest/{job_id} (and MCP get_backtest) now include queue_ahead / queue_position while status is enqueued, and progress_pct / progress_phase while running when a gateway backtester reports mid-run progress. Remote workers may omit progress until completion.

Account-level free cash across live credentials: GET /api/v1/me/available-cash sums free USDT/USDC/USD/FDUSD/BUSD per unique exchange (default credential), with by_exchange and incomplete when a venue fails. API keys need read:account. MCP get_available_cash and the public SDKs expose the same payload.
