Risk & Capital Management

Most traders focus on finding good trades. The professionals focus on not losing their account. Risk management is the single skill that separates traders who survive long-term from those who blow up. You need to understand this before you place a single trade.

The Math Nobody Tells You

Losses hurt more than equivalent gains help. This isn't psychology — it's pure math:

Why Avoiding Losses Matters More Than Making Gains
Start: €1,000 -10% loss = €900 Need +11.1% to recover Start: €1,000 -25% loss = €750 Need +33.3% to recover Start: €1,000 -50% loss = €500 Need +100% to recover

This is why professionals obsess over limiting losses. A 50% drawdown doesn't just hurt — it requires a 100% gain just to break even. Your first goal as a trader isn't to make money; it's to not lose it.

Risk of Ruin — Why Position Sizing Is Existential
Risk per trade → 0.5% Near-zero ruin. 200 consecutive losses needed. Forever safe. 1% <1% ruin. Standard professional sizing. Recommended default. 2–3% 10-20% ruin risk with normal losing streak. Use with caution. 5% 50%+ ruin risk. Wipe-out after moderate drawdown. 10% Ruin Risk 1% per trade. Your survival depends on sizing, not on finding better setups.

The 1–2% Rule

Professional traders risk a maximum of 1–2% of their total account on any single trade. Not 10%. Not "whatever I feel comfortable with." 1–2%.

Here's why: if you risk 2% per trade and have a rough streak of 10 losses in a row, you've lost 20% of your account. Painful, but survivable. You can recover. If you risk 20% per trade, 5 losses in a row = 100% gone.

Example: 1% Risk Rule in Action

Account size€10,000
Max risk per trade (1%)€100
Entry price€60,000 (BTC)
Stop loss€58,500 (−2.5%)
Risk per BTC€1,500
Position size = €100 ÷ €1,5000.0667 BTC

The position size comes from your risk budget — not from how much you "feel like" buying. This is the core of professional risk management.

Drawdown Recovery Math — Losses Are Asymmetric
DRAWDOWN NEEDED TO RECOVER VERDICT −10% +11.1% Easy — a few good trades −25% +33.3% Weeks to months −50% +100% Need to DOUBLE — years −75% +300% Almost impossible Losses compound asymmetrically. Avoiding a 25% DD is worth more than finding "hot" setups.

Risk/Reward Ratio

Before entering any trade, you should know: if this works, how much do I make? If this fails, how much do I lose? The ratio between those two numbers is your risk/reward (R/R).

R/R of 1:1 = you risk €100 to make €100. You need to be right more than 50% of the time to be profitable.
R/R of 1:2 = you risk €100 to make €200. You only need to be right 34% of the time to break even.
R/R of 1:3 = you risk €100 to make €300. You only need to be right 26% of the time to break even.

Break-Even Win Rate by Risk/Reward
1:1
Need 50% WR
1:1.5
Need 40% WR
1:2
Need 34% WR ✓
1:3
Need 25% WR ✓
The Goal: Minimum 1:2 Risk/Reward Never take a trade with less than 1:2 R/R. If your stop is 2%, your target must be at least 4%. This means even with a 40% win rate, you're still profitable. Good risk management can make even a mediocre strategy profitable.

Setting Stop Losses

A stop loss is your pre-defined exit point if the trade goes against you. You set it before you enter — never after. Here's where to put it:

Never Move Your Stop Loss to a Worse Position Moving a stop from -5% to -10% because "it'll probably bounce" is how accounts die. The stop is your risk limit — if you move it, you've broken your own rules. It's okay to move a stop to protect profits (trail it), but never to give a losing trade more room.
Rule Before Every Trade Before you click buy: write down 1) your entry price, 2) your stop loss price, 3) your target price. Calculate the R/R. If it's below 1:2, don't take the trade. This 30-second habit will save your account.
Practice: Calculate R/R Before You Trade Use the CryptoEdge Backtester to run a strategy and check if its average R/R is above 1:2. Real data, real numbers — not theory. Try CryptoEdge Lite
