Strategy decides how much you make. Risk decides how long you last. Today is the survival kit — the mathematics that keeps you in the game long enough for your edge to pay you.
They blow up from good analysis in oversized positions. You can be right 6 times out of 10 and still lose everything — if trade number 7 is five times the size of the others.
The professional's inversion
Amateurs ask "how much can I make?" Professionals ask "how much can I lose, and can I survive it?" — and answer that question before every entry.

The most important arithmetic in finance — and the reason professionals obsess over small losses.

The asymmetry nobody teaches beginners
A 50% loss needs a 100% gain.
DRAWDOWN RECOVERYwhat it takes to get back to break-even
Read the last row again
From −90%, you must turn €1,000 into €10,000 just to break even. This is why the professional obsession is never "how do I win big" — it's "how do I never take a wound that deep."
Day 13 · RUIN MATH · Section 01
The silent killer
Risk of ruin.
Risk of ruin is the probability that a losing streak ends your account before your edge can express itself. It depends on three things: your risk per trade, your win rate, and your R:R.
The lesson in one line
A profitable system with 10% risk per trade will still bankrupt you eventually — the streak always arrives. Small risk isn't caution; it's what makes the edge collectable.

⚡ Scored Checkpoint · The Mathematics of Ruin
Checkpoint 1: survival math.
1. After a −25% drawdown you need…
A +25% ✕
B +33% ✓
C +20% ✕
SolutionB. €10,000 → €7,500. To get back you need €2,500 on a €7,500 base = 33%. Losses always demand more than they took.
2. A profitable system with 10% risk per trade will…
A Make you rich fastest ✕
B Eventually be destroyed by a normal losing streak ✓
C Perform exactly like 1% risk, just faster ✕
SolutionB. Eight losses at 10% each is a −57% hole. The edge never gets the chance to pay because the account is gone first.
3. The professional's first question before a trade is…
A "How much can I make?" ✕
B "How much can I lose — and can I survive it?" ✓
C "What does social media think?" ✕
SolutionB. Downside is the only variable you control. Manage it and the upside eventually manages itself.

Section 02 · Position Sizing
The formula that saves you.
One equation, three markets, zero guessing — the most practical skill in this entire academy.
Day 13 · SIZING · Section 02
The foundation rule
Never risk more than 1%.
One percent of your account, per trade, maximum. On €10,000 that's €100 — regardless of how certain you feel. Certainty is a feeling; 1% is a rule.
Why 1% works psychologically
At 1%, a loss is boring. Boring losses don't trigger revenge trades. The rule protects your account and your mind at the same time.
BEGINNER
0.25 – 0.5%
While learning live execution. Small enough that tuition is cheap.
STANDARD
1%
The professional default once you've passed the 30-trade gate.
AGGRESSIVE
1.5 – 2%
Only with proven expectancy over 100+ trades. Rarely necessary.
NEVER
Above 2%
Not confidence — a countdown. One streak ends the account.
Three completely different instruments, three different position sizes — but the loss is always €100. That consistency is what makes 100 trades statistically meaningful.
Day 13 · SIZING · Section 02
The insight that fixes stop-loss anxiety
A wider stop is not more risk.
✕ The beginner's belief
"A wide stop means I lose more money"
So they squeeze stops into tiny distances
The stop sits inside the noise — and gets swept
Result: repeatedly right on direction, repeatedly stopped out
✓ The professional's truth
Risk is fixed at 1% — the stop's width changes the size, not the loss
Wide stop → smaller position. Same €100 at risk
The stop goes where the idea is wrong, never where it's convenient
Result: fewer stop-outs, and every loss is identical in size
Say it out loud
"The chart chooses the stop. The formula chooses the size." Once that clicks, stop placement stops being an emotional decision forever.

Checkpoint 2: the formula.
1. €20,000 account, 1% risk, stop 40 pips on EURUSD (€10/pip per lot). Size?
2. Your setup needs a stop twice as wide as usual. You…
A Tighten the stop to keep your usual size ✕
B Halve the position size — risk stays 1% ✓
C Skip risk management this once ✕
SolutionB. Stop width is dictated by the chart's invalidation point. Size is the variable you adjust — never the risk.
3. Position size is…
A An input you decide by conviction ✕
B An output of risk ÷ stop distance ✓
C Whatever the broker suggests ✕
SolutionB. Size is calculated, never felt. "I'm very confident" is precisely the mental state that oversizing punishes hardest.

Section 03 · R & Reward
Thinking in R.
Stop counting euros. Start counting risk units — the language professionals use to stay objective.
Day 13 · R & REWARD · Section 03
One unit to rule them all
R makes every trade comparable.
1R is simply the amount you risked. A trade that returns three times your risk is +3R — whether that's €30 or €30,000. The percentages and the psychology stay identical.
Why it protects your mind
"I lost €480" triggers panic. "I lost 1R" triggers a shrug and a journal entry. R strips the emotion out of the arithmetic — same information, no adrenaline.
R IN PRACTICE1R = €100 risk

⚡ Scored Checkpoint · R & Reward
Checkpoint 3: risk units.
1. At 1:3 R:R, break-even win rate is roughly…
A 50% ✕
B 25% ✓
C 60% ✕
SolutionB. One win of +3R covers three losses of −1R. Being wrong most of the time is perfectly survivable when the winners are big.
2. A setup offers only 1:1. You…
A Take it — action is good ✕
B Skip it and log the skip ✓
C Take it with double size ✕
SolutionB. At 1:1 you need to be right more than half the time just to pay the spread. The plan's minimum is 2R — and the plan doesn't negotiate.
3. Why journal in R instead of currency?
A To hide losses from yourself ✕
B It's comparable across account sizes and removes emotion ✓
C Brokers require it ✕
SolutionB. R keeps your statistics valid as the account grows — and keeps a −1R from feeling like a catastrophe.

Section 04 · Circuit Breakers
Limits that save your account.
Pre-set rules that switch you off before a bad day becomes a catastrophic month.
Day 13 · CIRCUIT BREAKERS · Section 04
Four layers of protection
Your personal risk limits.
PER TRADE
1%
Maximum loss on any single idea. Non-negotiable, computed by formula.
PER DAY
−2R
Two full losses and the platform closes. The day is over — no exceptions, no "one more".
PER WEEK
−5R
Stop for the week. Review the journal instead. Something is off in you or in the market.
OPEN RISK
Max 2%
Total exposure across all open positions — correlated trades count as one.
Why the daily limit matters most
Blown accounts almost never come from one bad trade. They come from the eighth trade of a bad day, taken at triple size, to "make it back". The −2R limit makes that trade impossible.
Day 13 · CIRCUIT BREAKERS · Section 04
The hidden way 1% becomes 4%
Correlated trades are one trade.
Long BTC, long ETH, long SOL, long a tech index — that feels like four positions at 1% each. It is really one position at 4%, because they all fall together when risk sentiment turns.
The rule
Before opening a second position, ask: "If today goes badly, do these lose together?" If yes — split the 1% between them or pick the better setup only.

Checkpoint 4: limits.
1. You hit your daily −2R limit at 10am. You…
A Close the platform — the day is over ✓
B Keep going, the day is young ✕
C Double size to recover before lunch ✕
SolutionA. The limit exists precisely for the moment you don't want to obey it. Tomorrow the market is still there — with a calm version of you.
2. Long BTC, ETH and SOL at 1% each means your real risk is…
A 1% — they're separate trades ✕
B Roughly 3% — one correlated bet ✓
C 0.33% — diversification ✕
SolutionB. Crypto majors move as one block. Three positions in the same cluster is leverage wearing the costume of diversification.
3. The weekly −5R limit exists to…
A Punish you ✕
B Force a review when something is clearly off ✓
C Satisfy the broker ✕
SolutionB. Five losses in a week means either the market regime shifted or your discipline slipped. Both are answered by the journal, not by more trades.

The unglamorous truth
3% a month sounds pathetic next to social-media screenshots. It doubles the account in two years — and, unlike the screenshots, it survives.

✓
Positive expectancy maintained at that size.
✓
Rule adherence above 90% over the sample.
✓

→
Then, and only then: increase size by ~25%. Never double.
⚠️ The scaling trap
After three winners, size feels too small. That impulse has ended more careers than any losing streak. Position size follows your statistics, never your mood.
📉 Scaling down
Equally important: after a −5R week or during personal stress, cut size in half until confidence and consistency return. Professionals shrink before they break.

Checkpoint 5: compounding.
1. 3% per month compounded for 24 months roughly…
A Doubles the account ✓
B Adds 36% ✕
C Barely covers costs ✕
SolutionA. 1.03²⁴ ≈ 2.03. Modest monthly percentages become dramatic totals — which is why survival matters more than speed.
2. You're allowed to increase position size when…
A You feel confident after 3 wins ✕
B 30+ journaled trades show positive expectancy and 90%+ adherence ✓
C Your account hits a round number ✕
SolutionB. Size increases are granted by data, not by emotion. Three wins is noise; thirty journaled trades is evidence.
3. After a −5R week the correct adjustment is…
A Increase size to recover faster ✕
B Halve size and review the journal ✓
C Switch to a brand-new strategy ✕
SolutionB. Shrink, diagnose, then rebuild. Increasing size inside a drawdown is the single fastest route to a blown account.

TAKEAWAY 1
Losses are asymmetric
−50% needs +100%. Keeping wounds shallow is worth more than any entry technique.
TAKEAWAY 2
Size is calculated
Risk fixed at 1%, stop set by the chart, size as the output. Never the other way round.
TAKEAWAY 3
