# Trading signal / investment alert subscriptions (mostly annual, delivered by email, no ads): a solo founder hit $9k/month in 12 months, listed at 3.8x revenue. The only gap to trading bots is regulation.

Why now, and how long the window lasts

'Annual plans + email delivery + zero ads' lets a solo signal service reach a 77% profit margin, with multiples close to the top of SaaS; but revenue is tied to performance and market conditions, and falls off if the market dips for a quarter (92wuubfl65's run-rate 0.63). This is not a window-type opportunity but a small business that exists long-term. The difference from trading bots ([084]) is that it doesn't place orders for users, so the regulatory burden is noticeably lighter.

Confidence

Low. Few samples, all seller-entered, no completed sales. What would overturn this: gvsf9enhrc cuts price or pulls the listing within 30 days. What would upgrade it: a comparable completed sale appears in the database, or several indie signal subscriptions with monthly revenue above $5k show up.

## Evidence

Grouped by store. Each group starts with the charts that can be graphed (real curves, data dates below the chart), then the scanner's original notes and source links.

Data 2026-09-29 → 2026-11-06 (39 days, 39 observations). Single-day swings are big, so look at the trend in the monthly breakdown above.

- Indie (30 days, as of 11-01): Zero G Trading (zerogtrading.com) $10,709, +314%, 13 subscriptions; Cryptobytez trading Discord (hosted on Whop) $2,933, +24%; more signal products are near zero (ForexCity Signal and Kachi AI are both under $10).

## Already doing it

Those three are the listings; on indie, Zero G Trading and a batch of paid Discord / Whop groups.

## The hardest step

Credibility of track record and compliance. Signals need public, verifiable history; many countries require licensing for 'investment advice' (inferred: the US publisher exemption requires content not to be tailored to individuals).

## Who it's for

People who actually trade and have a public record; annual subscriptions, delivered by email or Discord.

## Should every product builder know this?

No.

2026-11-02

Backfill check: all four listings still for sale, none cut in price. 92wuubfl65's report says '$212k ARR' (the headline figure); the database TTM is $260,900, and last month's annualized figure is only 63% of TTM. The report does not mention that it is declining.
