What it does

Two parts. Switch each one on or off.

Run one part, both, or neither. It watches the market and places the orders for you.

Daily stock part

One simple rule across about 2,400 US stocks.

When a stock’s 20-day average climbs above its 50-day average, it buys 1 share. When it drops back below, it sells.

  • Once a trading day, at the opening auction
  • It never borrows
  • Spare cash waits in the S&P 500 fund (SPY)

24/7 part

Crypto around the clock. Stocks in their extra hours.

It trades crypto at any hour and 50 US stocks outside normal hours, about $1,000 a buy. A trading model decides what to buy.

  • Switch it on or off in the app
  • Its model hasn’t shown an edge over a simple rule

Memory

It remembers. It learns from its mistakes.

Both parts keep a record of every call, check it once the result is in, and relearn each week from what went wrong.

  1. 01

    Remembers every call

    Every buy, sell and skip is saved on your computer, so nothing it decided is forgotten.

  2. 02

    Checks itself

    Once the result is in, each call is graded: did it make money, and by how much.

  3. 03

    Learns from mistakes

    Every week its models retrain on the latest results, misses included. The longer it runs, the more of its own calls it learns from.

  4. 04

    Proves it first

    The daily filter only acts after passing a test on results it hasn’t seen. Until then it watches. It hasn’t passed yet.

Learning isn’t a promise of better results, and it can still lose money. How it learns

Results

Honest results. It made less than the S&P 500.

In a 10-year replay of exactly how the daily part trades, it made about 11.8% a year. The S&P 500 made 14.9%.

The replay uses today’s list of stocks, which leaves out companies that later failed. So real results would likely be lower. Past results don’t predict future ones, and it can lose money.

Questions

Questions and answers

Does it make money?

It can, and it can lose money. In a 10-year replay the daily part made about 7% a year on its own, or 11.8% with spare cash in the S&P 500 fund, while the S&P 500 made 14.9%. Its drops were smaller on its own and as deep with the fund. See the results. Try it on paper and judge for yourself.

Does it learn from its mistakes?

Yes. It saves every call, grades it once the result is known, and retrains each week on what happened, its own misses included. Learning doesn’t guarantee better results: the daily filter only acts once it passes a test on results it hasn’t seen, and so far it hasn’t. See the results.

Do I need to leave my computer on?

It needs a Windows computer that’s on at the US market open (9:00 AM New York time), and for the 24/7 part, all the time. If you’d rather not leave yours on, run it on a cloud computer you rent.

What happens if I stop it?

Anything it bought stays in your account. To wind down, press Stop buying: it makes no new buys and sells each holding when its rule says, then tells you it’s safe to quit.

Can I get a refund on Pro?

Yes, within 14 days of your first Pro payment. Email us and we’ll refund it in full.

Which brokers does it work with?

Alpaca today, where a paper account is free. More brokers are coming soon.

Do I need to know how to code?

No. Install the app, paste your license key and add your Alpaca keys. It handles the rest.

Does it use real money?

Not unless you choose to. It trades on paper by default. Real money needs the Pro plan, your own live Alpaca keys and a typed confirmation in the app.

Will it make me money?

Nobody can promise that. In a 10-year replay the daily part made less than the S&P 500, and real results would likely be lower. It can lose money.

See the full results.

Does Vrot hold my money?

No. Your money stays in your own Alpaca account. The app places orders in it for you.

Where are my Alpaca keys kept?

On your computer. They stay there.

Does my computer need to stay on?

It needs to be on and awake at the US market open, 9:00 AM New York time, with an internet connection. The app only trades while it’s running.

Is Vrot part of Alpaca?

No. Vrot AI isn’t affiliated with Alpaca. You open your own account at alpaca.markets. A paper account is free.

Is this financial advice?

No. Nothing on this site or in the app is financial advice. Please read the risk disclosure.
