You can't watch the market all day. Something should.

ValphaSignet tracks the positions you enter, flags the moves that actually matter, explains them in plain language, and delivers them to LINE, email or in-app. It never asks for a brokerage login and can't touch your money.

What happens between a price moving and you deciding to act.

Four steps run whether you are looking or not — watch, detect, explain, deliver. Two more decide whether the result is worth trusting: what the record shows afterwards, and what the service is never allowed to touch.

Sample portfolio: 7 positions across US stocks, ETFs and crypto. All figures on this page are illustrative.

01 — Watch

Everything you hold, in one reading.

Enter your positions once. ValphaSignet keeps value, allocation, cost basis and open P&L current against quotes that refresh in seconds, and it treats a stock, an ETF and a coin as the same kind of row. Nothing is connected to a broker — you decide what is tracked.

02 — Detect

You decide what counts as news.

Price targets, RSI levels and unusual-move thresholds are set per position, with the channels chosen per rule. A rule stays armed until it crosses; crossing once is what makes it a notification.

Rules are yours, not a feed's. Nothing is pushed to you because it was trending.

Rules evaluate continuously while a market is open. Only a crossing sends a notification — no repeat while the condition stays true. Fundamentals alerts (RSI, P/E) are an Investor feature.

03 — Explain

Why it moved, not just that it moved.

Each significant move arrives with a plain-language read on the likely drivers, the filings and headlines behind them, and how far the position ran against its sector. The morning briefing does the same for the portfolio as a whole.

Daily briefing 14 Aug · 08:00 ICT
Illustrative

Your portfolio opened up 1.30%, driven almost entirely by NVDA and BTC. Six of seven positions are inside their normal daily range; TSM is the one holding giving ground.

Key drivers

  • Semiconductors led the tape after ASML guided Q3 revenue above consensus. Your semi weight is 32.5% of the portfolio.

    ASML Q2 release · 07:20

  • Treasury yields eased 6 bp after the CPI print came in line, which is the likely support under VOO.

    BLS CPI · 19:30 prev.

  • BTC held above 93,000 on steady spot ETF inflows; no position-level threshold was crossed overnight.

    3 headlines · 06:05

Holdings in focus

  • NVDA +4.21%
  • TSM −1.14%

Explanations are generated from filings and headlines published before 08:00 and are interpretive, not investment advice. Every claim links to the source it came from.

On the wording

Written in hedged language on purpose. A driver is shown with its source and timestamp so you can disagree with it.

Explanations are interpretive. Where the evidence is thin the briefing says so, rather than inventing a cause for a move that had none.

04 — Deliver

It reaches you where you already are.

LINE is a first-class channel here, not an afterthought. The alert arrives as a single Flex bubble carrying the price, the day's change, a sparkline and the reason — enough to decide whether to open anything at all.

If a channel fails, the alert falls back to the next one rather than disappearing. Delivery state for every alert is visible in the notification centre.

06 — Control

Read-only, by construction.

Manual entry is the trade-off ValphaSignet makes on purpose: a little setup, in exchange for a service that has nothing to connect to and nothing to lose on your behalf.

What it does

  • Reads only the positions and trades you enter yourself
  • Signs you in with OAuth through Clerk
  • Stores portfolio data encrypted with 256-bit AES in Supabase
  • Lets you delete a portfolio, or cancel a plan, from Settings

What it never does

  • Asks for brokerage credentials
  • Connects to a bank account
  • Places, cancels or routes an order
  • Holds, moves or has access to your money
