TD Ameritrade's thinkorswim platform supports iron condor order entry directly. You can build all four legs as a single combined order, review the net credit and probability metrics before submitting, and manage the position using the platform's built-in risk analysis tools. This guide covers the full process.
TD Ameritrade and thinkorswim in 2025
TD Ameritrade merged with Charles Schwab, and thinkorswim is now Schwab's flagship options platform. Existing TD Ameritrade accounts were migrated to Schwab. For new accounts, the thinkorswim platform is available through Schwab. The options trading functionality, including multi-leg order entry for iron condors, remains the same.
What Is an Iron Condor?
An iron condor combines a bull put spread below the current market price with a bear call spread above it. Both spreads collect premium at entry. The position profits if the underlying stays within the defined range through expiration. Tradematic is an automated iron condor trading platform that executes this strategy systematically using institutional market data, without requiring manual order entry.

Options Approval Levels at TD Ameritrade / Schwab
Iron condors require Level 3 options approval (defined-risk spreads). This level allows:
- Vertical spreads (both debit and credit)
- Iron condors (four-leg defined-risk positions)
To apply: log into your Schwab/TD Ameritrade account, go to Account Features → Brokerage → Options, and complete the approval application. Schwab evaluates trading experience, income, net worth, and investment objectives.
How to Enter an Iron Condor on thinkorswim
Step 1: Navigate to the Trade Tab
Open thinkorswim. In the Trade tab, type the underlying ticker (e.g., SPY or QQQ) into the symbol field. The options chain loads below the main chart area.
Step 2: Choose the Expiration Date
Expand the options chain and select your target expiration. The expiration header row shows days to expiration (DTE). Iron condors on standard monthly options typically use 20–45 DTE.
Step 3: Build the Put Spread (Lower Wing)
- Right-click the short put strike → Sell Single
- Right-click a lower put strike → Buy Single
These two legs appear together in the order queue at the bottom.
Step 4: Build the Call Spread (Upper Wing)
- Right-click the short call strike → Sell Single
- Right-click a higher call strike → Buy Single
thinkorswim combines all four legs into a single iron condor order automatically.
Step 5: Review and Submit
The order queue at the bottom shows:
- Net credit (positive number = credit received)
- Max profit and max loss
- Probability of expiring worthless (probability of profit)
Set a limit order near the natural midpoint. Click Confirm and Send, review the full order summary, then Send Order.
Monitoring the Position
Open the Monitor tab to see all live iron condor positions. Key metrics to watch:
| Metric | What It Tells You |
|---|---|
| Delta | Overall directional exposure (target: near zero) |
| Theta | Daily premium decay (positive = earning daily) |
| Gamma | Rate of delta change (increases near expiration) |
| P&L Open | Unrealized profit or loss on the position |
The Analyze tab's Risk Profile chart shows the P&L curve across all price scenarios — useful for visualizing where the position starts losing money.
Closing or Adjusting the Trade
To close early, right-click the open position in the Monitor tab and select Create Closing Order. thinkorswim generates a buy-back order for all four legs simultaneously.
Common management approaches:
- Close at 50% of max profit — reduces gamma risk in the final 2–3 weeks
- Roll the tested spread — if one side is challenged, buy it back and sell further out in time
- Close early on large moves — define a loss threshold before entry (e.g., 2× the credit received)

Limitations for Automated Trading
thinkorswim does not have a public API for automated order submission. Every iron condor trade must be entered manually. For traders who want systematic iron condor execution without screen time, Tradematic automates the full process on Tradier and tastytrade. Capital stays in the trader's own brokerage account — Tradematic never holds funds.
