The Lay of the Land

A US brokerage: SIPC-member, regulator-overseen, commission-free for stocks and ETFs like essentially every major broker now. Your securities are yours, held in your account. The company earns money from other things — payment for order flow, margin interest, subscription upsells — which explains the interface's enthusiasm. Know the business model and the design choices stop being mysterious.

The first thing the app shows you is a big number and a line chart of your day — engineered for a daily emotional check-in. From the Process course you already know what daily P&L glances do to decision-making. Treat the home screen as a hallway you walk through, not a room you live in. Your real reports are your written plan and your quarterly mirror.

Durable anatomy, whatever the icons look like this year: a SEARCH function to find any stock or ETF by name or ticker; a DETAIL page per security (price, chart, news, an order button); your PORTFOLIO list of current holdings; an ACCOUNT/settings area holding transfers, statements, tax documents, and recurring investments; and a NOTIFICATIONS system you will soon prune hard. Five concepts. Everything else is decoration.

A stock's page leads with the chart — the least useful thing on it. The durable value is below: fundamentals, news, and the order entry point. Notice what the default chart shows: a single day, the noisiest possible window. One tap stretches it to five years, where the picture you learned to read in Reading the Market actually lives. Make long-window charts a reflex.

Before any money moves, decide how you'll use this tool: the app is for EXECUTING decisions made elsewhere — on paper, in calm, per your plan — never for making them. Robinhood removed every friction between impulse and order; your written rules are the friction you reinstall on purpose. That's the whole philosophy of this course, and lesson eight makes it a complete workflow.
