仓位管理
外汇手数计算器
根据账户余额、计划风险、入场价和止损价确定合适的仓位大小。适用于 EURUSD、GBPUSD、USDJPY、黄金和白银。
交易存在风险。计算器结果基于您的输入进行估算；点差、佣金、隔夜利息、滑点、合约规格和经纪商执行情况都可能改变实际结果。

将结果作为规划数字，然后核对最小手数、点差和滑点。
比较经纪商计算器回答什么
它回答一个实际问题：如果这笔交易触及止损，什么手数能将亏损控制在计划金额附近？
它不会判断交易是否优秀。它只是连接图表与账户。止损较宽通常意味着较小仓位；止损较紧可能允许更大仓位，但前提是止损有真实的市场依据。
示例
| 输入 | 示例 | 为何重要 |
|---|---|---|
| 账户余额 | $10,000 | 您要保护的账户规模 |
| 每笔交易风险 | 1% | 止损触发时计划亏损 $100 |
| XAUUSD 入场 / 止损 | 2350 / 2340 | 按计算器假设的黄金 100 点止损 |
| 建议手数 | 0.10 手 | 在成本之前将计划风险维持在约 $100 |
使用结果前的检查
确认经纪商的合约大小、最小手数步长、平均点差、佣金和止损距离规则。黄金和白银因各经纪商规格不同而需特别注意。
如果计算出的手数低于经纪商最小值，在该止损距离下交易可能对账户过大。不要通过取消止损或增加风险来补偿。
Lot size formula
The basic idea is simple: planned money risk divided by stop distance and pip or point value. The calculator does that arithmetic for common forex, gold, and silver symbols, but your broker contract specification is still the final reference.
A wider stop should usually produce a smaller lot size. A tighter stop can produce a larger lot size, but only when the stop is placed where the trade idea is genuinely wrong.
When to use a lot size calculator
| Situation | How it helps |
|---|---|
| Before placing a manual trade | Turns planned account risk into a position size before emotion gets involved |
| Before trading XAUUSD | Makes gold contract size, stop distance, and money risk easier to compare |
| Before copying a strategy | Helps you understand whether the strategy drawdown fits your account allocation |
| After changing account balance | Keeps risk proportional instead of reusing an old lot size |
Mistakes to avoid
- Do not choose the lot size first and then move the stop to make the number feel comfortable. The stop belongs where the trade idea is wrong.
- Do not assume XAUUSD, EURUSD, GBPUSD, and USDJPY all behave the same at the same lot size. Contract specifications and pip values differ.
- Do not ignore spread, commission, swaps, and slippage. The calculator result is a planning estimate, not a guaranteed fill or final loss.
FAQ
What is lot size in forex?
Lot size is the position size of a trade. It controls how much each pip or point movement is worth in your account.
Can I use this calculator for XAUUSD?
Yes, but check your broker contract size, minimum lot, spread, and margin rules because gold specifications can vary by broker.
Is 1% risk per trade safe?
One percent is a common planning limit, but it is not automatically safe. Your stop distance, strategy drawdown, leverage, and account size still matter.
