Vertical Credit Spread Analyzer

Real options data. No guessing. Structured analysis for Bear Call and Bull Put spreads, sized to your actual budget.

What it does

1. Trend & Levels
Pulls 6 months of price history, identifies the nearest support/resistance, and estimates a probable 1-3 week trading range.

2. Volatility Check — Real IV, Not Estimates
Pulls actual implied volatility and Greeks from live options chains (ORATS-derived data), compared against historical volatility. Tells you plainly whether current conditions favor selling premium — or not.

3. Strategy Selection
Bear Call or Bull Put, chosen to match the trend and volatility read — never forced to fit what you came in wanting.

4. Strike Selection, Sized to Your Budget
A specific short/long strike pair, with max risk, max profit, and an approximate win rate via delta. Never proposes a position that exceeds your stated budget — and never fakes a workable trade out of a spread that isn't actually executable.

5. Expiration Selection
3-5 weeks out. No weeklies. Explains the buffer logic.

6. Risk Management
A specific defensive level and a take-profit target — only when a real position was actually proposed.

Why this one's different

Most bidding/signal tools will hand you a number no matter what. This one won't. If a spread's net credit comes out negative — a real, common outcome on tighter or less liquid names — it tells you that plainly instead of quietly rounding it to zero and handing you a fake trade. If your budget genuinely can't support a position, it says so instead of downsizing into something misleading.

Data

Live options chains and Greeks via Tradier, cross-checked against historical volatility. Every output ends with a clear risk disclaimer — this is technical analysis, not financial advice.

Who this is for

Small-account option sellers who want structure and discipline in their credit spread selection — not a black box that always has an opinion.

Setup Required

You'll need your own free Tradier Sandbox API token (no funding required):

1. Sign up at tradier.com — takes a few minutes
2. Generate a Sandbox token from your account API settings
3. Enter it when prompted after purchase

This keeps your data usage independent from other buyers and avoids shared rate-limit issues.

垂直信用价差分析工具 (Vertical Credit Spread Analyzer)

基于真实期权数据，不靠估算。为 Bear Call 和 Bull Put 价差策略提供结构化分析，按你的实际预算量身定制。

功能说明

1. 趋势与关键价位
拉取 6 个月价格历史，识别最近的支撑/阻力位，估算未来 1-3 周的概率价格区间。

2. 波动率检验——真实 IV，不是估算值
从真实期权链拉取实际隐含波动率和 Greeks（ORATS 派生数据），与历史波动率对比。明确告诉你当前市场条件是否有利于卖出权利金。

3. 策略方向选择
Bear Call 或 Bull Put，根据趋势和波动率判断选定——绝不会为了迎合你的预期方向而强行给出结论。

4. 行权价选择，按你的预算定制
具体的卖/买行权价组合，附最大风险、最大盈利、通过 delta 估算的大致胜率。绝不会推荐超出你预算的仓位，也绝不会把一个实际不可执行的价差硬凑成"可行"的交易建议。

5. 到期日选择
3-5 周后到期，不选周权，并说明这样选的原因。

6. 风险管理
具体的防御性平仓触发价位和止盈目标——只有在真正建议了仓位的情况下才会给出。

这个工具的不同之处

大多数信号类工具，不管条件如何，都会硬塞给你一个数字。这个不会。如果某个价差算出来的净信用是负数——在流动性较差或行权价间距较窄的标的上很常见——工具会直接告诉你,而不是悄悄把负数抹成零然后给你一个假的交易建议。如果你的预算确实撑不起一个仓位，工具也会如实说明，不会为了凑出结果而降级成一个容易误导人的仓位。

数据来源

期权链、Greeks（IV、delta）和历史价格数据均来自 Tradier Sandbox API——真实的 ORATS 派生数值，不是估算值。

使用前需要准备

需要你自己免费注册的 Tradier Sandbox API token（不需要入金）：

1. 前往 tradier.com 注册账号，几分钟即可完成
2. 在账号 API 设置里生成 Sandbox token
3. 购买后按提示填入即可

这样能确保你的数据调用独立于其他买家，避免共享限速导致的请求失败问题。

适合谁用

想在信用价差选择上保持纪律性和结构化判断的小资金期权卖方交易者——而不是一个不管什么情况都会给你一个"看法"的黑箱工具。
