Options Risk Management — Sizing, Rolling & Cutting Losses

Summary

The single reason 90% of retail option traders lose money is size, not strategy. Fix sizing first.

The 1% rule for defined-risk trades

Never risk more than 1-2% of the account on a single defined-risk options position. On the $100,000 TradeHQ practice account that's $1,000-$2,000 max loss per trade. Applied consistently, this lets you take dozens of trades without a single loss threatening the account.

The 3x rule for undefined-risk trades

Naked puts and short strangles have undefined loss potential. Professional risk desks cap capital at risk on any single underlying at 3x the credit received — meaning if you collect $200, you're prepared to buy back the trade at $600 and take a $400 realised loss.

Rolling — extending, not doubling down

Rolling is closing an existing option and opening a similar one further out in time (and sometimes at a different strike). It only works when you receive additional credit; rolling for a debit almost always compounds the original mistake. Set a rule: roll only for a credit, and only once per underlying per expiration cycle.

When to cut a loss

The simplest rule that outperforms most complex ones: exit any defined-risk long option position that loses 50% of its premium. Exit any short premium position that has doubled against you. These two rules alone stop most account-ending drawdowns.

Journaling every trade

For each trade record: thesis, IV rank at entry, position size in dollars, max loss in dollars, exit reason, actual P&L. After 50 trades you'll see your own edge and your own leaks. TradeHQ's ghost journal does this automatically on every simulated trade.

Key takeaways

• Cap defined-risk trades at 1-2% of account per position.
• Cap undefined-risk trades at 3x credit received.
• Only roll for a credit — rolling for a debit compounds mistakes.
• Cut long options at 50% loss, buy back shorts at 2x credit.

Check your understanding

• Recommended per-trade risk for defined-risk options: Options: 10-20%; 5-10%; 1-2%; 0.01%. Correct answer: 1-2%. Why: 1-2% per trade is the standard risk-management floor.
• Rolling should generally only be done: Options: For a debit; For a credit; On expiration day; Every day. Correct answer: For a credit. Why: Rolling for a debit compounds losses.
• Common exit rule for a long option is to cut it at: Options: 10% loss; 50% loss of premium; 90% loss; Only at expiration. Correct answer: 50% loss of premium. Why: The 50% rule protects against terminal decay.
• Why journal every trade? Options: Tax only; Identify your edge and leaks; Required by regulators; Boosts win rate automatically. Correct answer: Identify your edge and leaks. Why: Journaling surfaces real edge and recurring mistakes.
