Every trade you enter has two possible outcomes — it goes in your favor or it goes against you.
A stop loss is your plan for when it goes against you.
Without a stop loss — you have no plan. You are at the mercy of your emotions — and emotions in losing trades are terrible advisors.
A stop loss is a pre-defined price level at which your trade automatically closes — limiting your loss to a predetermined amount.
You set it when you enter the trade. If price reaches that level — the exchange closes your position automatically. No decision required. No emotion involved.
Example:
You buy Bitcoin at $80,000.
You set stop loss at $77,000.
If Bitcoin falls to $77,000 — your position closes automatically.
Maximum loss: $3,000 per Bitcoin — or whatever your position size calculates to.
Without stop loss:
Trade goes against you.
You tell yourself it will recover.
It keeps falling.
You still hold — hoping.
It falls further.
Now you are too deep to sell — “I will wait until it recovers.”
It never recovers to your entry.
Months later — account devastated.
This is called hope trading — and it destroys more accounts than any other mistake.
With stop loss:
Trade goes against you.
Stop loss triggers at $77,000.
You lose $3,000 — exactly what you planned.
You move on to the next trade.
Account intact. Trading continues.
Some traders argue stop losses are bad — they get triggered and then price reverses.
This is true sometimes. But consider:
Without stop loss — one trade can destroy your account.
With stop loss — no single trade can destroy your account.
The occasional stop out that leads to a reversal is a small cost. The protection against catastrophic loss is priceless.
A stop loss is not a sign of weakness. It is a sign of professionalism.
Market stop loss:
When price hits your level — order fills at market price.
Guaranteed to trigger — but may fill slightly worse than expected in fast markets.
Called slippage.
Limit stop loss:
When price hits your level — a limit order is placed at specified price.
More precise — but may NOT fill if price moves too fast past your level.
Risk of not being stopped out — dangerous in fast crashes.
For most traders: Market stop loss is safer — guaranteed execution.
The hardest part of stop losses is not setting them — it is keeping them.
The urge to move stop losses:
Trade goes against you. Stop loss approaching.
“Just a little more room — it will bounce.”
You move stop loss lower.
Price keeps falling.
You move it again.
Eventually — catastrophic loss.
Rule: Never move stop loss further from entry.
You may move it closer — locking in profit.
You may never move it further — increasing risk.
This rule must be absolute. No exceptions.
Too tight:
Stop placed just below entry.
Normal market noise triggers stop.
You are stopped out before trade has chance to work.
Frustrating and costly.
Round numbers:
Many traders place stops at $80,000 or $50,000.
Large players know this — they push price to these levels to trigger stops.
Called a stop hunt.
Place stops slightly beyond round numbers.
Obvious levels:
Right below major support that everyone can see.
Stop hunts target these obvious levels.
Add buffer beyond the obvious level.
Stop loss should be placed at a level where your trade idea is proven wrong.
Long trade:
Your idea: price will bounce from support.
Stop loss: below the support level.
If price closes below support — your idea is wrong. Stop out.
Short trade:
Your idea: price will reject from resistance.
Stop loss: above the resistance level.
If price closes above resistance — your idea is wrong. Stop out.
The stop loss answers: “At what price is my trade idea proven incorrect?”
