QuantSignals FST——从研究到执行的受监督 AI 交易
FST 将专有的 QS Research 信号连接到具备账户感知能力的决策、硬性风险限制、订单预览与审批、受监控执行以及可审查的会话记录。
核心要点
- QuantSignals FST 是一款受监督的 AI 交易 Agent，并非对无人值守盈利的承诺。
- 其运行闭环为：筛选、获取信号、交易、监控、暂停和学习。
- 每一笔订单都受到所选账户、已认证的券商能力、风险政策、预览、审批设置和对账流程的约束。
- 新用户可以先在 QS 模拟交易中评估其行为，再连接符合条件的真实账户。
- FST 可在 QS Web 应用、桌面端和 CLI 界面、iOS 及 Android 上运行。
QuantSignals FST 的功能
QuantSignals FST 是一款受监督的 AI 交易 Agent，可将来自 QS Research 的市场论点带入受边界约束的券商工作流。它筛选机会，阅读支持和反驳该论点的证据，检查是否符合投资组合配置，计算风险预算，预览订单，遵循账户的审批政策，监控形成的仓位，并记录全过程。
FST 不会消除市场风险，也不保证盈利结果。其目的在于提升决策和执行流程的一致性、可观测性与可追责性，同时将硬性控制置于语言模型之外。
该产品是横跨 QS Research、FST 和 QS Brokerage 的一个互联系统。Research 提供带时间戳的证据；FST 将这些证据转化为明确的交易论点和政策决策；Brokerage 则负责账户能力、风险执行、订单执行、对账以及权威订单记录。
工作原理
- 选择目标账户 —— 选择 QS 模拟交易，或选择一个当前能力已针对所请求操作完成验证的账户。
- 启动受监督会话 —— FST 会筛选已配置的标的范围，读取 QS 信号证据，并叙述市场状态和交易论点状态。
- 应用政策和风险规则 —— Agent 检查投资组合适配度，计算受限敞口，并拒绝违反账户规则或风险规则的计划。
- 预览、审批和对账 —— 订单会先被预览，遵循已配置的审批政策，路由至准确的账户，并根据券商响应完成对账。
- 监控和暂停 —— FST 会跟踪价格、交易论点、止损、目标价和市场状态，直至仓位被平仓、减仓、加仓，或依据政策继续持有。
常见问题
QuantSignals FST 是什么？
QuantSignals FST 是一款受监督的 AI 交易 Agent，将 QS Research 信号连接至具备账户感知能力、受风险治理约束的券商执行和持续仓位监控。
FST 是完全自主的吗？
FST 可以在预先配置的边界内运行自动化会话，但它仍处于受监督状态：账户资格、能力检查、硬性风险限制、审批政策、对账、止损控制和安全默认设置都会约束其可执行的操作。
FST 保证盈利吗？
不保证。交易存在风险，模拟交易结果并不代表未来真实交易结果，任何 AI 交易 Agent 都无法保证盈利结果。
没有真实券商账户也能测试 FST 吗？
可以。QS 模拟交易是默认评估路径，用户可在考虑接入符合条件的真实账户之前，观察完整的会话运行行为。
FST 可在哪些平台运行？
FST 可通过 QS Web 应用、桌面端和命令行界面、iOS 及 Android 使用。

QuantSignals FST — Supervised AI Trading from Research to Execution
FST connects proprietary QS Research signals to account-aware decisions, hard risk limits, order preview and approval, monitored execution, and a reviewable session record.
Key Takeaways
- QuantSignals FST is a supervised AI trading agent, not a promise of hands-off profits.
- The operating loop is screen, signal, trade, monitor, park, and learn.
- Every order is constrained by the selected account, certified broker capabilities, risk policy, preview, approval settings, and reconciliation.
- New users can evaluate behavior in QS paper trading before connecting an eligible live account.
- FST runs across the QS web app, desktop and CLI surfaces, iOS, and Android.
What QuantSignals FST Does
QuantSignals FST is a supervised AI trading agent that carries a market thesis from QS Research into a bounded brokerage workflow. It screens opportunities, reads the supporting and conflicting evidence, checks portfolio fit, calculates a risk budget, previews an order, follows the account's approval policy, monitors the resulting position, and records what happened.
FST does not remove market risk and does not guarantee a profitable outcome. Its purpose is to make the decision and execution process more consistent, observable, and accountable while keeping hard controls outside the language model.
The product is one connected system across QS Research, FST, and QS Brokerage. Research supplies time-stamped evidence; FST turns that evidence into an explicit thesis and policy decision; Brokerage owns account capabilities, risk enforcement, execution, reconciliation, and the authoritative order record.
How It Works
- Choose a destination — Select QS paper or an account whose current capabilities have been verified for the requested operation.
- Start a supervised session — FST screens the configured universe, reads QS signal evidence, and narrates the market and thesis state.
- Apply policy and risk — The agent checks portfolio fit, calculates bounded exposure, and rejects plans that violate account or risk rules.
- Preview, approve, and reconcile — Orders are previewed, follow the configured approval policy, route to the exact account, and reconcile against the broker response.
- Monitor and park — FST tracks price, thesis, stop, target, and market state until the position is exited, reduced, added to, or held under policy.
Frequently Asked Questions
What is QuantSignals FST?
QuantSignals FST is a supervised AI trading agent that connects QS Research signals to account-aware, risk-governed brokerage execution and continuous position monitoring.
Is FST fully autonomous?
FST can run an automated session inside preconfigured boundaries, but it remains supervised: account eligibility, capability checks, hard risk limits, approval policy, reconciliation, stop controls, and safe defaults constrain what it can do.
Does FST guarantee profits?
No. Trading involves risk, paper results do not represent future live results, and no AI trading agent can guarantee a profitable outcome.
Can I test FST without a live brokerage account?
Yes. QS paper trading is the default evaluation path so users can observe the complete session behavior before considering an eligible live account.
Where does FST run?
FST is available through the QS web app, desktop and command-line surfaces, iOS, and Android.
