What a Stock Alert Service Is
A stock alert service sends a notification when something specific happens in a stock: a price level is reached, a scan condition is met, or an analyst publishes a setup with its levels.

What to Take Away
- A stock alert is a notification that a defined condition has been met: a price level, a scan rule or an analyst's published setup.
- A well-formed published alert names the levels it is read from, the price that would invalidate it, and the time it was sent.
- The price when an alert is read can differ from the price when it was sent, and that difference changes the risk being described.
- A published alert is written for every recipient at once and knows nothing about any one reader's account.
- A record worth reading includes every closed alert, losers included, each measured from the entry stated at the time.

One Alert, Read Twice
The same published alert describes a different trade to a reader who opens it at once and a reader who opens it an hour later.
This lesson is part of a MAD Academy plan.
Three kinds of alert
A stock alert service sends a notification when something specific happens in a stock. The trigger can be a price the reader chose, a condition that software checks across the whole market, or a setup an analyst publishes with its levels attached. In every case the alert carries information, and the decision stays with the person reading it.
| Kind | Who sets the condition | What the notification says |
|---|---|---|
| Price alert | The trader, in advance | Price has reached a level chosen earlier |
| Scanner alert | A rule run by software | A stock now meets a stated set of filters |
| Published alert | An analyst at a research service | A described setup, the levels it is read from and what would invalidate it |
The first two are tools: the reader defines the condition and the software watches for it. The third is content, written by somebody else about a situation they have studied. That difference decides how each one should be read. A price alert reports on a decision the reader already made; a published alert describes somebody else's reading of a chart, which the reader then has to evaluate.
What a well-formed alert contains
A published alert that names only a ticker is a headline. What makes one usable is the set of prices that define the idea, because those are the only parts of it that can be checked against a chart.
Identifies the ideaBounds the idea
- Ticker and time sentWhich security, and the moment the reading was made
- The reference levelThe price the setup is read from, such as a breakout level or an entry zone
- The objectiveWhere the structure projects, if it completes
- The invalidationThe price at which the setup no longer exists
- The reasoningWhich structure, volume or event the levels come from
The time stamp is the field most often ignored. A level chosen at 9:45 describes the chart at 9:45. Read at noon, after the stock has moved, the same words describe a situation that may no longer exist, and the stop loss and objective now sit at different distances from the current price.
Why the price on the alert and the price on the screen differ
An alert is sent at one moment and read at another, and stocks keep trading in between. The faster and thinner the stock, the larger the gap between the price the alert describes and the price available to anybody acting on it.
| Factor | Effect on the price a reader actually sees |
|---|---|
| Time between send and read | Price has moved, sometimes through the reference level and well past it |
| Liquidity | A thinly traded stock moves further on the same number of orders |
| The bid-ask spread | The price quoted on a chart is the last trade, and the price available is the ask or the bid |
| Many readers at once | A notification that reaches many people together can move a small stock by itself |
The risk moves with the price
The risk-reward an alert describes is measured from its reference level. A fill well above that level carries a larger distance to the invalidation and a smaller one to the objective, so the same alert describes a different trade to a reader who arrives late. That is the mechanism of slippage, applied to a notification.
Published analysis and personal advice
A published alert goes to every subscriber at once, in the same words. It is general analysis of a security, and it has no knowledge of any individual reader's circumstances. Personal advice is a different thing: it is shaped to one person's situation, and it starts from the facts about that person.
- Account size, and therefore what a given position size means for that account.
- Other positions already held, which may be correlated with the one described.
- Time horizon, and whether the account can hold through an overnight gap.
- Tolerance for loss, and what a move to the invalidation level would mean in dollars.
- Tax situation, which this library describes as mechanics and never as advice.
A published alert knows none of those things. Whether to act on one at all, at what size and with what exit, is a decision only the reader can make, because only the reader holds the information it requires. That is why a published alert describes a setup and never tells a particular person what to do with their money.
Checking a record
Any service that publishes alerts produces a record, and the record is only informative when it is complete. The useful form lists every closed alert, the losers included, each measured from the entry stated at the time it was sent to the exit, so the result can be reproduced from the time stamps.
| What the record shows | What it does and does not establish |
|---|---|
| Every closed alert, losers included | The full distribution of outcomes, which is the only thing a reader can evaluate |
| A selection of the largest winners | The best outcomes, and nothing about the typical one |
| Returns measured from the day's low | A price nobody was told to use at the time |
| Testimonials in place of a record | One person's experience, chosen by the publisher |
| Results that cannot be matched to time stamps | Nothing that can be checked |
The second and fourth rows are the recurring shapes in the fraud red flags article, and the rules covering how results and endorsements may be presented are in the promotion and disclosure article. A record that only ever shows its best entries describes its marketing.
How MadStockAlerts uses this
MadStockAlerts publishes premium alerts of the third kind. Each one is scored by software and reviewed by an analyst before it sends, and each states the levels the setup is read from. They are educational analysis, not financial advice, and none of them is a recommendation to buy or sell a security.
Every premium alert that has closed, measured from the stated entry to the exit, with the losing trades included.
