Start in a simulator

3 min read · Why you should start day trading in a simulator, what a simulator can't teach you, and a simple 30-session plan with a written record.

A simulator is a practice account that uses real market prices and fake money. Most trading platforms offer one, and it is the cheapest way to learn, so if you start anywhere, start here.

Most people who day trade lose money, and many of them lose it while learning the basics. A simulator lets you make those beginner mistakes for free. It also lets you test whether you can follow your own rules.

Why start in a simulator

The first weeks of trading are mostly about mechanics. You learn how to place a bracket order, where your stop sits, and what a 20-point move feels like. On one MNQ contract, that 20 points is $40. In a simulator, a mistake costs nothing but a note in your record.

A simulator also gives you a clean test of the plan itself. You can see whether your setup shows up often enough, and whether you take it when it does. I keep my own public record in a simulated account, posted in points after every New York close. Points let you judge the method without the account size getting in the way.

What a simulator can't teach you

A simulator is useful, but it is not the real thing, and two gaps matter most.

  • Fills. Simulators often fill your orders more kindly than a real market would. A limit order may fill in the sim when it would have missed live. Stops may show less slippage than you'd get on a fast news move.
  • Emotions. Fake money doesn't make your hands shake, but real losses do. Many people follow their rules well in a sim and then break them with real money on the line.

So treat good sim results as a first pass, not proof. If you can't follow your rules in a sim, you won't follow them live. If you can, that's a good start, but it is not a finish line.

A simple 30-session plan

Here is a plan you can start this week. It follows the same steps I use: narrow, record, judge, repeat.

  1. Narrow. Pick one market, one setup and one session. Write the rules on one page.
  2. Fix your size. Trade the same size every time, such as one MNQ contract, and don't change it during the 30 sessions.
  3. Record every session. After each one, write down your trades in points, whether you followed every rule, and one sentence on how you felt.
  4. Judge the process. After 30 sessions, count your rule breaks before you look at profit. A small profit with many rule breaks is a warning, not a win.
  5. Repeat or stop. If the record shows you can follow the plan, run another 30. If it doesn't, you've learned something real without losing money.

Thirty sessions is not a magic number. It is simply enough days to see patterns in your own behavior, and few enough to finish. The Trading Record course walks through each step in more detail, including what to write down after every session.

The takeaway

Start in a simulator, because it lets you learn the mechanics and test your discipline for free. Remember that a sim flatters your fills and hides your emotions. Run a fixed number of sessions, keep a written record, and judge yourself on rules followed before profit. If the record says this isn't for you, that is a good and cheap answer.

Do this today

  • Open a simulator account on any platform and place one practice bracket order.
  • Write your one-page plan: one market, one setup, one session, one fixed size.
  • Set up a simple record with columns for date, trades in points, rules followed and one note.

Check yourself

Answer each one in your head, then open it to check.

What are the two main things a simulator can't teach you?

Realistic fills and real emotions. Sims often fill orders more kindly than live markets, and fake money doesn't create the same pressure.

Why trade the same size in every simulator session?

Fixed size keeps your results comparable, so you are judging the method and your discipline, not changes in size.

After 30 sessions, what should you look at first?

Your rule breaks. A profit made while breaking rules is a warning, because the process that produced it isn't repeatable.
