Trading at 16: how to get an account, which apps work, and what to do with the next two years

You searched for trading apps for 16 year olds and got lists that contradict each other. Here's how it actually works at 16, which apps to ask about, and the thing nobody tells you: the two years before 18 can be the most useful of your trading life if you use them right.

Getting an account at 16

Every regulated broker opens accounts for people under 18 the same way: a custodial account. It's your money and your trades, with a parent or guardian's name on the paperwork until you're of age. Most big brokers set one up in a day.

The apps and their rules change, so instead of trusting a list, ask any broker one question: do you offer custodial accounts? If the answer is yes, they're on your list.

What to do with the next two years

Most people who start trading at 18 with their own account lose it in the first stretch, because they're learning the routine with real money. You get to learn the routine now, on paper and at small custodial size, and arrive at 18 with the only thing that actually decides whether you keep an account: the habit of following your own rules on a red day.

That isn't a smaller version of trading. It's the part the 18 year olds skip.

The routine, from day one

• Before the session. Read your rules. Write down what you'll trade, the size, and the loss at which you stop for the day.
• During. Take only the trades that match your rules. That's the whole job, and it's harder than it sounds. Put a stop-loss on everything.
• After. Log every trade, including the ones you shouldn't have taken, with a line on why.
• The stop. When you hit the daily loss you wrote down, you're done for the day. That goes for paper too, especially for paper, because if you won't stop when the money is fake, you aren't going to stop when it's real.

Do that for a stretch and your journal will tell you something the videos can't: whether you can follow rules you wrote yourself. If the answer isn't yet, that's the most valuable thing you can learn at 16, and it cost nothing.

The way to make it stick is to give the routine a shape outside your head. Put the session in MoreLife as a block with a hard end, and tell it the loss rule. When the block ends, it asks: stopped at the number? Logged? A yes takes ten seconds. A no gets a question, which is the point.

Where 16 year olds go wrong

Not the account. The routine, which falls apart exactly because the money is small or fake. You stop logging. You stop reading the rules first. You trade when you're bored instead of when there's a setup. By 18 you have two years of bad habits and a real account to spend them in.

FINRA's page on day trading and their plainer one on risk are worth twenty minutes before the first real trade.

The short version

Custodial account at a major broker, paper for the routine. Ask the one question. Use the two years the way the 18 year olds wish they had. Rules before, log after, hard stop, even when the money is fake. And give the routine a witness.
