Signal Deck is a research and alerting tool for stocks: next-day model predictions, watchlist alerts, and strategy simulations. It is not financial advice, and it does not place trades on your behalf.
Email us at hello@signalstock.markets and we'll get back to you. This covers account issues, subscription/billing questions, bug reports, and anything else not answered below.
Common questions
Is Signal Deck financial advice?
No. Signal Deck publishes a statistical model's output, nothing more. It does not know your finances, goals, or tax position, and it never tells you to buy or sell. Treat every number here as one input among many, and talk to a licensed advisor before you act.
What do the rank, the call, and the odds mean?
Each night the model estimates, for every stock we track, the odds that it beats the market over the next trading session. "The market" here means the median stock among the roughly 950 US stocks we track, not an index. Those odds cluster close to 50%, so we lead with each stock's rank in that day's list: "Top 4%" means only 4% of scored stocks ranked higher. The top 20% are Outperform calls, the bottom 20% Underperform, and the middle 60% In line.
The edge is small and we report it as it is. In walk-forward testing, the model's top-ranked tenth of stocks beat the median stock about 52.5% of the time and the bottom tenth about 48%. An Outperform call is relative: the stock can still fall if the whole market falls.
How often do predictions update?
Once per trading day. A batch job runs after the close, refreshes prices and features, scores the tracked tickers, and publishes before the next open. Nothing on the predictions screen moves intraday; watchlist alerts do check live prices during market hours.
How do I change or turn off a watchlist alert?
Open the Alerts tab, go to Rules, and tap the rule you want to change. You can adjust the threshold and how sensitive it is to short-term price noise, or remove the rule entirely.
How do I manage or cancel my subscription?
Open Account in the app and tap "Manage subscription," which takes you to your Apple ID subscription settings. Subscriptions are billed and managed entirely through the App Store; we don't have a separate billing system.
How do I delete my account?
Open Account in the app, scroll to the bottom, and tap "Delete account." This is permanent and removes your profile, watchlist, and settings. No app on hand? Use the web deletion page instead. See our Privacy Policy for what's kept and for how long.
Is my data being sold?
No. See our Privacy Policy for exactly what we collect and who it's shared with.
