Two Golden Crosses, One Cron Job
Workflow diary: a nightly script against the screener API caught Veeva and Atlassian on the August 25 Golden Cross list. The numbers one week later.
Second entry in the workflow diary. This one is for people who'd rather read JSON than scroll a page. The whole setup runs without opening the site.
The five-line workflow
Every evening a cron job calls the REST API:
GET /api/v1/screeners/golden-cross?limit=100
Two fields in the response do most of the work. dataDate is the snapshot date the whole result set comes from, and generatedAt is the UTC time it was read. The script saves each day's symbols under their dataDate and prints the difference to the previous snapshot. New crossovers show up in my inbox as five lines of text. If a request ever needs several pages, passing date=<dataDate> pins every page to the same snapshot, so the diff never mixes two days.
What the diff said on August 25
The Golden Cross list for Tuesday, August 25 had 40 names. The diff line I cared about had two of them: Veeva Systems (VEEV) at $244.36 and Atlassian (TEAM) at $168.79. Two large, liquid enterprise-software stocks printed the same long-term crossover on the same day. A 50/200 cross is slow and mechanical. When it shows up on two names from the same part of the market at once, I take it as saying something about that part of the market, and only then about the names.
For both, I did the two-minute check in the browser afterwards: chart first, then the AI chat next to it, asking for the volume trend and whether participation was growing into the crossover. At 11 pm I'd rather read that answer than work it out myself.
One week of numbers
| Symbol | Cross (Aug 25) | Worst close after | Latest in this entry | Change |
|---|---|---|---|---|
| VEEV | $244.36 | never below cross price | $279.23 (Sep 2) | +14.3% |
| TEAM | $168.79 | $166.49 (-1.4%, Aug 26) | $192.08 (Aug 31) | +13.8% |
The two got there differently. Veeva barely moved for two sessions, $244 to $245, then jumped to $282.13 in a single session on August 28 and has stayed around that level since. Atlassian first dipped below its crossover price, the only time either stock was underwater, then climbed almost every day: $185.62 on the 28th, $192.08 on the 31st. Same event, same day, same sector, two different speeds.
The honest footnote
The August 25 list had 40 crossovers, and these are the two that did best in the group I was watching. Golden crosses also appear on charts that go nowhere afterwards, and one week says nothing about the next. What I wanted to show is how little effort the workflow takes: a mechanical event, caught by a script against a documented API, delivered as a diff and checked in two minutes with the chat. The screener did the watching. The decisions were mine.
