Quick Answer — Breakout Position Sizing
- • The 50% rule: never risk more than half your 3% daily drawdown limit on a single trade. That's 1.5% of your account per trade.
- • On a $100K account, your daily limit is $3,000. Max risk per trade: $1,500. This gives you two full shots before stopping.
- • Position size formula: Risk Amount / (Stop Distance % × Leverage) = Position Size as % of Account.
- • At 5:1 BTC leverage, a 0.3% BTC move against you equals 1.5% account drawdown. That's your entire safe risk budget on one trade.
- • Altcoins at 2:1 leverage require wider stops relative to account impact, making position sizing more forgiving but profits smaller per trade.
Strategy context: The approach outlined here is built around Breakout's specific rule set — 5:1 BTC/ETH leverage, 3% daily loss limit, no consistency rules, and 24/7 markets. What works on futures prop firms won't translate directly to crypto. Your results depend on execution, risk management, and market conditions.

Position sizing is the single most important skill at Breakout. Your analysis can be perfect, your timing can be spot-on, and you can still lose your account if you size wrong.
The 3% daily drawdown limit is unforgiving. One oversized trade during a volatile move and you're done. Here's the exact math for every account size, every stop distance, and every leverage level.
The 3% Daily Drawdown Explained
Breakout resets your daily drawdown limit at UTC midnight. Each day, you can lose up to 3% of your starting daily balance (which equals your previous day's closing equity) before the account is breached.
| Account Size | 3% Daily Limit | 50% Rule (Max/Trade) | 33% Rule (Conservative) |
|---|---|---|---|
| $25,000 | $750 | $375 | $250 |
| $50,000 | $1,500 | $750 | $500 |
| $100,000 | $3,000 | $1,500 | $1,000 |
| $200,000 | $6,000 | $3,000 | $2,000 |
| $250,000 | $7,500 | $3,750 | $2,500 |
The 50% rule: never risk more than half your daily limit on one trade. Two losses at 1.5% each = 3%. You're at the daily limit and must stop. This is the standard approach during evaluations.
The 33% rule: risk only one-third of your daily limit per trade. Three losses at 1% each = 3%. This is the conservative approach for funded accounts where preserving capital matters more than speed.
The Position Sizing Formula
Here's the formula:
Position Size (notional) = Risk Amount / Stop Distance %
Then check that notional against your leverage limit:
Max Notional = Account Size × Leverage
If the calculated position exceeds your leverage limit, reduce the position or widen your stop.
Practical Example: BTC at $90,000
Account: $100K | Daily limit: $3,000 | Max risk per trade: $1,500
Stop distance: $1,350 below entry (1.5% of BTC price)
Calculation:
- Risk per BTC: $1,350
- Max risk budget: $1,500
- Position size: $1,500 / $1,350 = 1.11 BTC
- Notional value: 1.11 × $90,000 = $100,000
- Leverage used: $100,000 / $100,000 = 1:1
At 1:1 leverage with a 1.5% stop, you risk exactly $1,500. Clean and safe.
What If You Want a Tighter Stop?
Stop distance: $450 below entry (0.5% of BTC price)
- Risk per BTC: $450
- Max risk budget: $1,500
- Position size: $1,500 / $450 = 3.33 BTC
- Notional value: 3.33 × $90,000 = $300,000
- Leverage used: $300,000 / $100,000 = 3:1
At 3:1 leverage with a 0.5% stop, you still risk $1,500. But now a 0.5% BTC move hits your stop. That's a $450 BTC price move — roughly 5-10 minutes of normal BTC volatility. Tight stops at high leverage get stopped out constantly.
How Leverage Interacts With Position Sizing
This is where traders get burned. Leverage amplifies both gains and losses proportionally to your account.
| BTC Move | 1:1 | 2:1 | 3:1 | 5:1 (max) |
|---|---|---|---|---|
| 0.3% | 0.3% | 0.6% | 0.9% | 1.5% |
| 0.6% | 0.6% | 1.2% | 1.8% | 3.0% (daily limit) |
| 1.0% | 1.0% | 2.0% | 3.0% (daily limit) | 5.0% (BREACH) |
| 2.0% | 2.0% | 4.0% (BREACH) | 6.0% (BREACH) | 10.0% (BREACH) |
The critical insight: at 5:1 leverage (max for BTC), a mere 0.6% adverse BTC move wipes your entire 3% daily limit. BTC moves 0.6% in minutes during normal trading. At full leverage without a tight stop, you're gambling.
Safe leverage zones for swing trading:
- 1:1 to 2:1 — comfortable room for 1-2% stops
- 2:1 to 3:1 — workable with 0.5-1% stops
- 3:1 to 4:1 — tight, requires 0.3-0.5% stops that get clipped easily
- 5:1 — only for very tight, very confident scalp-style entries with immediate stops
Altcoin Position Sizing at 2:1 Leverage
Altcoins on Breakout get 2:1 leverage maximum. The math changes significantly.
Example: ETH at $3,000 (Wait — ETH Gets 5:1)
ETH is in the same tier as BTC. 5:1 leverage. Same calculations apply.
Example: SOL at $150
Account: $100K | Max risk: $1,500 | Stop: 3% below entry ($4.50 per SOL)
- Risk per SOL: $4.50
- Position size: $1,500 / $4.50 = 333 SOL
- Notional: 333 × $150 = $50,000
- Leverage: $50,000 / $100,000 = 0.5:1
At 0.5:1 leverage on SOL with a 3% stop, you're well within limits. Altcoin position sizing at 2:1 is generally more forgiving because the lower leverage cap prevents you from oversizing.
The catch: altcoins move faster than BTC. A 3% SOL stop that would hold for days on BTC might get triggered in hours on SOL. The wider percentage moves on alts compensate for the lower leverage, but the volatility also means more frequent stop-outs.

Common Position Sizing Mistakes
Mistake 1: Calculating Risk Without Fees
Every round trip on Breakout costs 0.08% (0.04% per side). On a $200K notional position, that's $160 in fees. If your calculated risk is $1,500, your actual risk is $1,660. If you're close to the daily limit, fees can push you over.
Always add 0.08% of your position's notional value to your risk calculation.
Mistake 2: Ignoring Slippage on Stops
Your stop at $86,500 might fill at $86,450. That's $50 per BTC of additional loss. On a 2 BTC position, that's $100 of unexpected slippage. During high-volatility events, slippage can be worse.
Build 0.1-0.2% slippage buffer into your risk calculations.
Mistake 3: Adding to Losing Positions
You're down $1,000 on a BTC trade. Instead of closing, you add to the position to "average down." Your total risk is now $1,000 (existing loss) plus the new position's risk. You've effectively doubled your exposure. If BTC continues down, you breach the daily limit in a single candle.
If a trade is going against you, reduce or close. Don't add.
Mistake 4: Running Multiple Positions Without Aggregate Risk Tracking
Long BTC and long SOL simultaneously. Each position is sized at $1,500 risk. But if crypto dumps across the board, both positions lose at the same time. Your aggregate risk is $3,000 — the entire daily limit — not $1,500 per position.
Track your total portfolio risk, not just individual position risk.
Frequently Asked Questions
What's the maximum risk per trade on Breakout?
Breakout's 3% daily limit means your maximum risk per trade should be 1.5% of account (the 50% rule). On a $100K account, that's $1,500 per trade, giving you room for two losses per day.
How do you calculate position size on Breakout?
Divide your maximum risk amount by the stop-loss distance in percentage terms. Breakout example: $1,500 risk / 1% stop distance = position notional of $150,000 (1.5:1 leverage on $100K account).
Does leverage affect position sizing at Breakout?
Yes. Breakout's 5:1 BTC leverage amplifies moves — a 0.3% BTC move equals 1.5% account impact at full leverage. Higher leverage requires tighter stops or smaller positions to stay within the 3% daily limit.
What happens if you breach Breakout's daily drawdown?
Breakout permanently closes your account if you exceed the 3% daily drawdown limit. No second chances, no appeals. The breach is based on unrealized + realized P&L hitting 3% below your starting daily balance.
Should you use the 50% rule or 33% rule at Breakout?
Use the 50% rule (1.5% risk/trade) during Breakout evaluations for faster progress. Switch to the 33% rule (1% risk/trade) once funded to protect your account and income stream with three attempts per day.
How do fees affect position sizing at Breakout?
Breakout charges 0.04% per side (0.08% round trip). On a $200K notional position, that's $160 in fees. Add this to your risk calculation — fees can push you past the daily limit if you're near the edge.
Can you hold multiple positions at Breakout?
Yes, but track aggregate risk. Breakout counts all positions against the 3% daily limit. Two positions at $1,500 risk each means $3,000 total risk — your entire daily budget consumed if both lose simultaneously.
What stop-loss distance works best for BTC on Breakout?
At Breakout, 1-2% BTC stops at 1-2:1 leverage are the sweet spot for swing trades. This gives you $900-$1,800 of stop room per BTC at $90K pricing, keeping risk well within the 1.5% per-trade budget.
How do you size altcoin positions on Breakout?
Breakout gives altcoins 2:1 max leverage, so position sizing is naturally more conservative. A 3% SOL stop at 1:1 leverage risks the same percentage of account as a 0.6% BTC stop at 5:1 leverage. Wider stops are normal for alts.
What's the biggest position sizing mistake on Breakout?
Ignoring aggregate risk across multiple open positions. Breakout's 3% daily limit applies to ALL positions combined. Two "safe" individual positions can equal an unsafe total exposure if both move against you at the same time.
The bottom line: position sizing at Breakout is pure math. The 3% daily limit is your hard constraint. Use the 50% rule (1.5% max risk per trade), calculate your stop distance, determine notional size, and check against leverage limits. At 5:1 BTC leverage, a 0.3% move equals 1.5% account impact — that's your entire safe risk budget on one trade at max leverage. Stay at 2-3:1 for swing trades, add fee and slippage buffers, and always track aggregate risk across multiple positions. Traders don't fail at Breakout because of bad analysis. They fail because they sized too big for their stop distance.
