The Mechanics of Trading
Learn how financial markets move, how to place orders with precision, and how to protect your money. Master the fundamentals of price action, position sizing, and risk control without the hype.
Like Duolingo, but for The Mechanics of Trading. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 10 levels across 2 sections, about 20 minutes end to end, roughly 4 days at five minutes a day. It moves through Executing and Reading the Market and Managing Risk and Building Discipline. It starts from scratch.

Key ideas in The Mechanics of Trading
- Market orders fill immediately at whatever price is available
- Limit orders specify a maximum price you will pay but might sit unfilled if the price moves away
- The fundamental trade-off is speed and guaranteed fill versus price control
- Buyers pay the higher ask price while sellers receive the lower bid price
- The gap between the bid and the ask goes to the market maker providing liquidity
- You instantly start at a slight loss equal to the spread the moment you enter and exit
- The quoted price on your screen is just the last traded price or best available quote at that split second
- Fast-moving markets consume available orders instantly, forcing your market order to fill at the next available higher price
- This price difference between expectation and execution is called slippage
- Paper trading builds familiarity with order ticket buttons, order types, and platform mechanics without financial risk
- Simulated trading lets you practice reading bid-ask spreads and order fills safely
- Paper trading does not recreate the fear, greed, and hesitation that come when real money is on the line
- A candlestick summarizes the open, high, low, and close for that specific period
- The thin lines (wicks) mark the absolute price extremes of the session
- The thick colored body marks where the price started and where it ended
- A long wick represents price rejection where one side attacked but got overwhelmed
