Rules and discipline

Boring is a superpower

Watch a great basketball player shoot free throws. They do the exact same thing every time: bounce the ball three times, breathe, look at the rim, shoot. It's boring. It also works.

Trading is the same. Discipline means doing what your rules say, every single time, even when you don't feel like it.

Why doing it the same way matters

Remember expectancy from the Fruit level. A strategy with an edge only shows it over many trades. One trade is close to a coin flip. A hundred trades is where the edge appears.

But that only works if every trade is taken the same way. If you follow your rules on Monday, skip them on Tuesday, double your size on Wednesday and "just try something" on Thursday, you aren't trading one strategy. You're trading four, and you'll never know which one is making or losing the money.

A good trade vs. a winning trade

This is one of the most important ideas in the whole school:

• A good trade is one where you followed your rules.
• A winning trade is one that made money.

They are not the same thing! You can follow every rule and still lose, because every strategy has losers. You can break every rule and still win, because luck happens.

The dangerous one is the lucky win. When breaking a rule makes money, your brain learns "breaking rules works." Then it does it again, usually with bigger size, until the luck runs out.

So grade yourself on following the plan, not on the money from one trade. The money comes from lots of good trades added together.

Tools that help

• A checklist. Pilots run a checklist before every flight, even after 10,000 flights. Make a short one: Is this my setup? Is my stop set? Is my size right? Am I calm? If any answer is no, there's no trade.
• A daily loss limit. Pick a number, like 2 losing trades or $50. When you hit it, you're done for the day. No arguing with yourself.
• A max number of trades. For example, 3 a day. This stops you from clicking just because you're bored.
• Set hours. Trade the same time window each day, and stop when it ends.
• Orders placed up front. Put your stop and target in the moment you enter, so you don't have to decide anything in the heat of the moment.

How discipline breaks

It rarely breaks all at once. It breaks a little at a time. "Just this once I'll move my stop." "Just this once I'll trade during the news." Each "just this once" makes the next one easier.

Treat your first broken rule like a smoke alarm, not a small thing. Stop, write down what happened, and go back to the plan.

Remember

• Discipline means following your rules every time, even when it's boring.
• A good trade follows the plan. A winning trade makes money. They aren't the same.
• Grade yourself on following the rules. Profits come from many good trades over time.
• Checklists, a daily loss limit and a max number of trades keep you on track.
