Your First Bull Put Spread on IBKR: From Level 3 Permissions to Position Exit
Bull Put Spread is the ideal first strategy for options sellers: maximum loss is locked in before entry, margin requirements are low, and the logic is clean. This guide walks through every step on IBKR — from applying for Level 3 permissions to placing a Combo order and setting your 50% profit exit.
- The Bull Put Spread is the most beginner-friendly options-seller strategy: maximum loss is fully defined before entry, margin requirements are modest, and the logic is straightforward.
- Executing a Bull Put Spread on IBKR requires Options Level 3 permissions (spread trading requires this tier).
- New traders must first practice on a paper trading account for 2–3 months — confirm you understand both the strategy logic and your own emotional responses before committing real capital.
- This article walks through every step: what a Bull Put Spread is → how to apply for IBKR permissions → how to select contracts → how to place the order → and how to manage the position to exit.
Why Choose a Bull Put Spread Instead of Selling a Naked Put?
In earlier articles we covered the logic behind selling puts, but selling a naked put carries one critical problem for beginners: your maximum loss can exceed expectations.
If you sell one AAPL $180 Naked Put, the margin requirement may reach $4,000–$6,000 (the broker requires you to hold enough capital to take assignment), and in theory your losses grow the further the stock falls — with no floor.
The Bull Put Spread solves this problem:
Two simultaneous actions: sell a higher-strike Put (collect premium) + buy a lower-strike Put (pay premium for protection). The net result is a credit — your maximum profit — while the difference between the two strike prices minus that net credit becomes your maximum loss.
Sell the higher-strike Put
Collect premium
This is your primary strategy leg
Buy the lower-strike Put
Pay a smaller premium
This is your protection leg (caps maximum loss)
The key point: your maximum loss is $360, and you know that figure exactly before you enter — it cannot grow beyond it. A $5 spread width is the ideal starting point for beginners: the tuition is controlled, yet the trade is real enough to teach you how the strategy behaves. This is the defining advantage of a Bull Put Spread — downside risk is defined, so you learn within a known boundary.
Phase 1: IBKR Account Setup and Options Permissions
Go to interactivebrokers.com and select "Individual Account." Taiwan residents should choose IBKR LLC (the U.S. entity). Documents required:
- Passport or national ID
- Proof of residential address (utility bill or bank statement within the past three months)
- Tax identification number (Taiwan residents use their national ID number)
In the IBKR web portal, navigate to: Account Management → Trading Permissions → Options, and apply for Level 3 (which enables spread trading). IBKR will ask about your options trading experience — answer honestly:
- Level 1: Buy calls and buy puts only
- Level 2: Sell covered calls and cash-secured puts
- Level 3: Execute spread strategies (Bull Put Spread requires this level) ⭐
IBKR offers a free paper trading account that runs in sync with live markets. To activate it: IBKR Portal → Paper Trader Account → Enable.
Recommended: practice for 2–3 months and complete at least 5–10 simulated trades. Focus on observing:
- Your psychological response when the position shows an unrealized loss
- Whether you can mechanically execute the 50% profit-taking / 2× stop-loss rules
- Whether you can resist the impulse to "just wait a little longer"
- Essential for single-stock options: let at least one position run through an earnings event — observe the full cycle of IV expanding into earnings and then collapsing afterward (IV Crush). This experience cannot be learned from a textbook.
Phase 2: Selecting the Underlying and the Contracts
For Bull Put Spread underlying selection, use PVL's Four-Filter System:
- Filter 1 — Sponsorship: PVL A/D Rating ≥ C (institutional buying continues; not distribution)
- Filter 2 — Moat: ROE ≥ 17%, EPS YoY growth > 25% (financially sound fundamentals)
- Filter 3 — Volatility: IV Rank in the 30–80% sweet zone (premium is rich but risk is reasonable)
- Filter 4 — Technicals: Stock price holding above its 50-day moving average (intermediate uptrend intact; never sell puts into a downtrend)
Options on SPY (S&P 500) and QQQ (Nasdaq 100) offer the following advantages:
- No single-stock black-swan risk — naturally diversified
- No earnings events — no IV Crush risk; the volatility curve is more predictable
- Best liquidity in the entire market; extremely tight Bid/Ask spreads and minimal slippage
- Weekly expiration options (Weekly Options) available — maximum DTE flexibility
- IV closely tracks VIX — learn to use VIX as an entry timing tool
- Ideal for building the muscle memory of "pure system execution" without stock-selection noise
Open the underlying's Options Chain in IBKR TWS:
- Expiration date: Select the expiration tab at 30–45 DTE
- Short Put strike price: Find an OTM Put near Delta -0.25 (approximately 8–12% below the current stock price)
- Long Put strike price: Choose one strike below the short put leg (typically $5 or $10 lower)
- Confirm liquidity: Both strikes should have OI ≥ 500 and a reasonable Bid/Ask spread
Phase 3: Placing the Order in IBKR TWS
A Bull Put Spread is entered in IBKR as a Combo Order — both legs execute simultaneously, eliminating the risk of one leg filling while the other does not:
- Search for the underlying in TWS and open the Options Chain
- Locate the short put strike price, right-click → "Sell"
- In the same expiration, locate the long put strike price, right-click → "Buy"
- TWS will automatically recognize this as a spread combination and display the combined Net Credit
- Set the order type to Limit Order — price it near the midpoint of the Bid/Ask
- Confirm the Net Credit is positive (you are collecting premium, not paying it)
Phase 4: Managing the Position to Exit
Immediately after entry, set two exit conditions in TWS (using Conditional Orders or Alerts):
| Exit Condition | Trigger | Action |
|---|---|---|
| Profit Target | Spread value decays to 50%–55% of the original premium (e.g., collected $1.40; buy back at $0.63–$0.77) | Buy to close — do not wait for expiration |
| Stop Loss | Spread value exceeds 2× the original premium (e.g., collected $1.40; cost to buy back is now $2.80 or more) | Buy to close immediately — take the loss |
This is not a "set it and forget it" strategy. Spend at least 30 minutes each week reviewing:
- Is the stock still trading above its 50 MA? (If it breaks below, evaluate whether to exit early)
- How many days until the next earnings report? (If earnings fall within the holding period, consider closing early)
- Has the unrealized P&L reached the stop-loss threshold?
- If the 50% profit target has been reached — close the position immediately, without hesitation
