ApproveDecline
Strategies you can read, not black boxes.
Each strategy is a plain rule set: where it looks, what it filters out, how it scores what's left. You pick the ones your account runs, and set four basics for each: how much of the account it may use, its stop loss, its largest position, and when to take profit.
Seasonal Retail
Retailers heading into seasonal demand: back-to-school and the holidays.
Energy
Energy companies with clear tailwinds: seasonal gas, oil, uranium and power.
Yearly Bounce Back
Stocks sold off into the end of the year, bought December 22 and sold the first trading day of January.
Collapse Filter
Combine it with your strategies: before each buy plan, a model leaves out stocks whose recent prices look like a coming collapse. It never buys or sells on its own.
Your Own Rules
Start from any of 29 indicators, from MACD and RSI to candlestick patterns. HAi1Y helps you write the rule, shows what it would pick today, and backtests it. The Gringotts team reviews it before it trades.
A trading day, on a clock you can see.
Gringotts checks the market every hour it's open. What it does at each check follows the same rules every day, and every action lands in your ledger.
Check
Every strategy rescans its stocks and re-checks the day's earlier decisions.
Buy plan
New money is spread across the strategies' picks. The plan waits for your approval.
Sell by the rules
A stock sells when it drops off its strategy's list for long enough, or hits your stop loss or take profit.
Balance
A strategy that has grown well past its share is trimmed back, gains first.
Report
The close: what happened today, with a chart. Weekly and monthly reports follow.
You're in charge, with two controls.
The Control Panel is on your Account page. The one switch that lets Gringotts act without asking takes a deliberate full slide.
Trading
- Active
- Buys and sells by your strategies' rules.
- Inactive
- No new buys; stocks still sell at the right time. For vacations.
- Sell Now
- Sells everything, then holds cash.
Approval
- Daily Buy Plans
- Each morning's plan waits for your Approve or Decline. Decline early and you can get a different plan.
- Buys Automatically
- Plans are placed without asking, still through every safety check.
Backtest
See how your strategies would have done.
Gringotts replays your own strategies, with your own settings, on past prices, side by side against the market as a whole (SPY). Past results don't predict future ones, and the replay says what it can't see.

HAi1Y explains, so you decide.
HAi1Y is the chat in Gringotts. Ask about a strategy, a stock or your account and get facts from your own data, laid out as tables and charts. HAi1Y never gives investment advice.

HAi1Y's button is on every tab and starts with what you're looking at.

Good to know
Gringotts is made by MobA11y, a mobile company that builds simple, accessible apps for people who struggle to find truly accessible experiences in a category, starting with investing. Modern investing apps take a lot of interaction; Gringotts helps you understand and automate the work, with HAi1Y to help where an interface falls short.
- Gringotts is not a broker. Your money stays in your own brokerage account (Public.com today), and Gringotts places orders there for you.
- Gringotts doesn't give investment advice. Strategies are rules you choose; HAi1Y explains them and never tells you what to buy.
- Investing involves risk, including the loss of money. Backtests replay the past and don't predict the future.
- Only buys you approve are placed, unless you turn on Buys Automatically. Stocks you bought yourself are never touched.
