Core changes: - Refactor FastAnalysisService: single LLM multi-factor analysis replaces 7-agent pipeline; add multi-timeframe consensus, threshold calibration, confidence calibration, multi-model ensemble voting - Add RAG memory injection and reflection validation (analysis_memory + reflection worker) - Simplify billing config: remove unused strategy_run/backtest/portfolio_monitor, add ai_code_gen separate billing (different token consumption scale) - Settings hot-reload after save, no backend restart needed Frontend: - Global dark theme overhaul: pure black palette replacing blue-tinted colors across sidebar/header/dashboard/analysis/K-line/user-manage/profile/settings/billing - Fix USDT payment modal dark theme (portal rendering broke CSS selectors) - Refactor position modal: direction + quantity + entry price, remove add/reduce logic, show raw DB values on re-open, save exactly what user inputs - Fix Polymarket prediction market dark text - i18n for position modal title Backend: - Position management: one record per symbol (DELETE+INSERT replacing ON CONFLICT with side), fixes PnL showing 0 when switching long/short - MarketDataCollector data fetching optimization - portfolio_monitor scheduled monitoring improvements - env.example reorganized: common config first, advanced config last Documentation: - README architecture diagram updated to FastAnalysisService flow - Add virtual position, AI tuning config, billing items documentation - Add INDICATOR_DEFINITIONS_CN.md, FRONTEND_FAST_ANALYSIS.md Made-with: Cursor

# 技术指标计算口径（与代码一致）
|
||
|
||
本文档与 `backend_api_python/app/services/market_data_collector.py` 中 `_calculate_indicators` 及子函数实现**严格对应**。
|
||
|
||
| 指标 | 实现要点 |
|
||
|------|-----------|
|
||
| **RSI(14)** | **Wilder RSI**：前 14 期涨跌分别取简单算术平均作为初始均幅；自第 15 期起 `avg = (avg_prev×13 + 当期) / 14`。RS = 均涨幅/均跌幅，RSI = 100 − 100/(1+RS)。 |
|
||
| **MACD(12,26,9)** | 收盘 **EMA12、EMA26**（首值=各自前 N 根 **SMA**，再按 α=2/(N+1) 递推）。**DIF** 从第 26 根 K 起有定义；对 DIF 子序列再算 **EMA9** 得 **DEA**；柱 = DIF − DEA。至少需要 **34** 根收盘才能稳定给出信号线（子序列长度≥9）。 |
|
||
| **MA5/10/20** | 最近 N 根收盘价的 **SMA**。 |
|
||
| **枢轴 Pivot** | **上一根 K** 的高、低、收：P=(H+L+C)/3，R1/S1/R2/S2 标准式。 |
|
||
| **摆动高/低** | 最近 **20 根 K** 的 `max(high)`、`min(low)`。 |
|
||
| **布林(20,2)** | 中轨 = 最近 20 收盘 **SMA**；方差 = Σ(x−μ)²/**20**（总体方差）；σ=√方差；上下轨 = 中轨 ± 2σ；带宽% = (上轨−下轨)/中轨×100。合成支撑/阻力使用 **`BB_upper` / `BB_lower`** 字段。 |
|
||
| **ATR(14)** | **Wilder ATR**：TR 定义同经典；首 ATR = 前 14 个 TR 的简单平均；之后 `ATR_t = (ATR_{t-1}×13 + TR_t) / 14`，递推至**最后一根 K**（全序列，非仅尾窗）。 |
|
||
| **量比** | 当前根成交量 / 近 **20** 根成交量算术平均。 |
|
||
| **区间位置 %** | (当前收盘 − 近20低) / (近20高 − 近20低) × 100；高=低 时为 50。 |
|
||
| **合成支撑/阻力** | `(R1 + swing_high + BB_upper) / 3` 与 `(S1 + swing_low + BB_lower) / 3`，见 `levels.method`。 |
