交易洞察AI驱动的金融情报
交易洞察快速解答： 仓位管理是你在每笔交易中做出的最重要的风险管理决策。核心公式：手数 = (账户余额 x 风险百分比) / (止损点数 x 每点价值)。每笔交易的风险不应超过1-2%。本指南涵盖5种仓位计算方法，并附有示例、工具和可下载的计算器。
[SECTION 2]一个胜率 40% 但头寸规模合理的交易者，将始终优于一个胜率 70% 但头寸规模糟糕的交易者。每一次都是如此。即使您拥有世界上最好的入场策略——如果每笔交易冒 10% 的风险，连续 7 次亏损就会让您的账户减半。数学不会在意您的图表分析。
头寸规模决定了您能存活多久。生存时间就是一切——因为只要有足够的交易次数，即使微小的优势也能复利成可观的回报。
公式： 手数 = (Account x 1%) / (止损 x Pip Value)
每笔交易只承担账户1%的风险。以10,000美元账户为例：最大风险 = 100美元。如果你的止损是20个点，交易EURUSD（每手每点价值10美元）：100美元 / (20 x 10美元) = 0.5手。
Why 1%? At 1% risk, you need 69 consecutive losses to lose 50% of your account. At 5% risk: only 14 losses. At 10%: just 7. The 1% rule gives you time — and time is what lets your edge compound.
公式： f* = (bp - q) / b where b = win/loss ratio, p = win probability, q = 1-p
凯利公式告诉你为了长期最大增长应承担的最优风险比例。如果你有45%的胜率，且盈亏比为2:1：f* = (2x0.45 - 0.55)/2 = 17.5%。完整的凯利公式建议风险17.5%——这非常激进。
多数专业人士使用半凯利（8.75%）或四分之一凯利（4.4%）。 Kelly only works if you know your TRUE win rate. Most traders overestimate theirs. Use conservative estimates.
Fixed-pip stops make no sense when volatility changes. A 20-pip stop on a calm day might be 2x ATR. The same stop on NFP day might be 0.3x ATR.
公式：手数 = (账户余额 x 风险百分比) / (ATR倍数 x ATR值 x 每点价值)
Use 2x ATR for swing trades, 1.5x ATR for intraday. This method automatically adjusts position size to current market conditions — tighter stops in calm markets, wider in volatile ones.
RoR = ((1-Edge)/(1+Edge))^(Capital/AvgLoss)
目标是将破产风险控制在2%以下。风险为2%时，你有98%的生存概率。若破产风险为5%，则有二十分之一的概率爆仓。这对专业交易来说是不可接受的。计算你当前的破产风险，并调整仓位大小，直到其降至2%以下。
| Account Size | Max Risk/Trade | Lot Type | Example (20 pip SL) |
|---|---|---|---|
| $500 | $5 (1%) | Micro (0.01) | 0.03 lots |
| $1,000 | $10 | Micro | 0.05 lots |
| $5,000 | $50 | Mini | 0.25 lots |
| $10,000 | $100 | Standard | 0.50 lots |
| $50,000 | $500 | Standard | 2.50 lots |
