Risk management

Module 10 of 12 · Trading From Scratch

If you remember only one module from this entire course, make it this one.

Risk management is the least exciting topic in trading and the single most important.

It is, quietly, the whole game.

The real job is not getting wiped out

Beginners think trading is about picking winners. It is not. Even skilled traders are wrong constantly.

The real skill is making sure that being wrong never costs you much, so you survive long enough to get good.

Everything below is just how to do that on purpose.

Rule 1: never risk money you need

Money for rent, food, bills, and your future is untouchable. It does not go anywhere near a trade. You only ever trade with money you could lose completely without it changing your life.

This is not a motivational nicety. Trading with rent money makes you desperate, and desperate people make terrible decisions. The calm you need to trade well is impossible when the stakes are your survival.

Rule 2: the 1 percent rule

Here is the rule that keeps professionals alive: on any single trade, never risk more than about 1 percent of your total pot.

With a $1,000 account, that means a single bad trade should cost you no more than $10. Not $50, not $200. Ten dollars.

That sounds almost insultingly small, and that is exactly the point. If no single trade can cost you more than 1 percent, then no single mistake, and no run of bad luck, can ever wipe you out. You get to keep playing, and keep learning, no matter how many you get wrong.

Rule 3: always set a stop-loss

You met the stop-loss in Module 6: the order that automatically sells you out at a price you choose, capping your loss.

Risk management is where it earns its keep.

The discipline is simple. Decide where you are wrong before you enter, while you are calm, and set the stop-loss there.

Then the decision is made by your sensible self, not your panicking self. Serious traders set one on every single position, no exceptions.

Position sizing: how it all connects

Now the piece that ties it together, and the part most beginners never learn. The 1 percent rule and your stop-loss, working together, tell you exactly how much to buy. Watch:

• Your account is $1,000, so your maximum loss on a trade is $10.
• You want to buy a stock at $50, and you decide your stop-loss goes at $48. That means you are risking $2 per share.
• How many shares can you buy? Take your $10 of allowed risk and divide by the $2 of risk per share. That is 5 shares.

So you buy 5 shares. If the trade goes against you and the stop-loss triggers at $48, you lose exactly $10, the 1 percent you planned for.

You did not guess how much to buy. The risk rules decided it for you.

That is position sizing, and it is the difference between a professional and a gambler.

Rule 4: losses are tuition

You accepted this at the very start of the course, and it deserves saying plainly. A losing trade where you followed all your rules is a good trade. A winning trade where you broke your rules is a bad trade, because you just got lucky, and luck teaches terrible habits.

Judge yourself on whether you followed your plan, never on whether one trade happened to win. The wins and losses average out over time. The discipline is what compounds.

That is risk management. Trade only money you can lose, risk about 1 percent per trade, set a stop-loss every time, let those rules size your position, and treat losses as the price of learning.

It will never feel as exciting as a big win.

But it is the only reason anyone is still in the game long enough to have one.
