The 1% rule in options trading means never risking more than 1% of your total account value on a single trade. On a $10,000 account, that's a maximum of $100 at risk per position. The goal is to survive a losing streak without material damage to your capital base.
Why 1% (and Not More)
The logic is about drawdown math. If you risk 5% per trade and hit 5 consecutive losers, you've lost 25% of your account. Recovering 25% requires a 33% return — a significant hill. At 10% per trade and 5 consecutive losses, you're down 50% and need a 100% return to recover.
At 1% per trade with 5 consecutive losses, you've lost 5% of the account. That's recoverable within weeks of normal trading. Some traders use 2% as the threshold, which is a common middle ground — still conservative enough to survive rough patches.
Iron condors, as defined-risk strategies, have a hard maximum loss built in. Unlike directional positions that can lose more than expected if the market gaps, the worst-case on an iron condor is the spread width minus the credit received, per contract. This makes the 1% rule easier to implement precisely.
How to Apply the 1% Rule to Iron Condors
The "risk" on an iron condor is the maximum loss per contract, which is:
Max loss = (Spread width - Credit received) x 100
For a 5-point wide iron condor where you collect $1.00 credit:
- Spread width = $500 per contract
- Credit = $100 per contract
- Max loss = $400 per contract
To risk no more than 1% on a $10,000 account ($100 max risk), you would need fractional contracts — which isn't possible in standard options. In practice, a single 5-point iron condor contract on a lower-priced underlying (or a micro-contract where available) may be the smallest feasible position at this account size.
A more realistic rule at small accounts is to cap exposure rather than use strict 1% sizing. You might risk $200–$300 on a single iron condor (2–3% of a $10,000 account) while maintaining no more than two or three positions open at once.
Practical Position Sizing Table by Account Size
| Account Size | 1% Max Risk | 2% Max Risk | Suggested Iron Condor Size |
|---|---|---|---|
| $5,000 | $50 | $100 | 1 contract (2-point wide spread) |
| $10,000 | $100 | $200 | 1 contract (5-point wide spread) |
| $25,000 | $250 | $500 | 1–2 contracts (5-point wide spread) |
| $50,000 | $500 | $1,000 | 2–3 contracts or 1 on wider spread |
| $100,000 | $1,000 | $2,000 | 3–5 contracts, diversified underlyings |
These are starting points. The right number of contracts depends on the spread width, the credit received, and how many positions you're running simultaneously.
Position Sizing vs. Trade Count
The 1% rule applies per trade. If you have three iron condors open simultaneously, your total account risk is 3% under the 1% rule. Some traders run a portfolio-level risk limit — for example, total open risk no more than 5–10% of the account — in addition to per-trade limits.

The Wing Width Question
One consequence of applying the 1% rule is that it drives you toward narrower spreads or fewer contracts. A 2-point wide iron condor has a smaller max loss than a 10-point wide one — but it also collects less credit. Finding the right trade-off between width, credit, and position size is a core skill in iron condor management.
A tighter spread (say, 2 points wide) on a higher-probability trade might make more sense for small accounts following strict risk rules than a wider spread that requires too much capital at risk to run within the rule.
How Tradematic Handles Risk Sizing
Tradematic is an automated iron condor trading platform that builds position sizing into its execution rules. Rather than requiring traders to manually calculate risk per trade, Tradematic uses account balance, the credit received, and spread width to deploy positions in proportion to the account. Risk management is systematic, not manual.
Account minimum is $1,000, with typical accounts in the $5,000–$20,000 range.
Frequently Asked Questions
What is the 1% rule in options trading? The 1% rule means limiting the maximum loss on any single trade to 1% of your total account value. On a $10,000 account, that's $100 at most at risk per trade.
Is 1% risk per trade too conservative for options? For most retail options traders, 1–2% is appropriate. It allows you to withstand a losing streak without material account damage. Traders with very small accounts may find strict 1% sizing impractical due to minimum contract sizes.
How do I calculate risk on an iron condor? Max loss per iron condor contract = (Spread width - Credit received) x 100. For a 5-point wide spread with $1.00 net credit, max loss is $400 per contract.
Can I use the 1% rule with automated options trading? Yes. Automated platforms like Tradematic incorporate position sizing rules that scale with account balance. The 1% concept is built into how positions are sized across the account.
What is a reasonable risk limit per trade for a $10,000 options account? Many experienced traders use $100–$200 (1–2%) per trade on a $10,000 account. With 2–3 positions open simultaneously, total portfolio risk stays within $300–$600.
Trading involves risk and losses can occur. Past performance does not guarantee future results. Options trading is not suitable for all investors. Only allocate capital you are comfortable risking.
