Inside MarketPlay's backend: 10 automated roles, one approval gate

MarketPlay is a financial literacy game with ten task-specific tools working behind the scenes. They draft scenario copy, grade checkpoint tests, watch the paper-trading broker and flag unusual activity in the six-tab analytics dashboard. None of them can publish a change or take an action until I approve it.

I chose that structure because MarketPlay deals with a teenager's financial decisions, even when the money is simulated. An unreviewed mistake matters more here than it would in a typical side project. The tools handle repetitive work, but I remain responsible for anything that reaches a user.

Each tool has one narrow job. One drafts the next scenario in the reel curriculum. Another watches the paper-trading order flow for possible problems with fills or settlement. A narrow role is easier to review and easier to fix when something goes wrong.

GetAITrade follows the same rule with real trading. Software can connect to the broker, read a Telegram instruction and prepare an order, but a person must confirm before it executes. That approval step is the reason I'm comfortable using automation near anyone's money.

I designed and built every part of MarketPlay's control room myself. The main lesson is simple: decide what automated software must never be allowed to do before deciding what it can do.
