Introduction
Stop losses for options trades work differently from stock stop losses. You don't set a stop based on the underlying asset's price — you set it based on what it would cost to close the options position itself. For iron condors and spreads, this means defining a maximum buyback price relative to the credit you initially received.
Why Stock-Style Stop Losses Don't Work for Options
For stocks, a stop loss at $490 on a $500 position makes intuitive sense. For options, the price of the option moves based on multiple factors — not just the underlying price — including time decay, implied volatility, and how far in or out of the money the strike is.
Setting a stop at "close if the underlying drops to $490" might trigger prematurely on an options position that still has weeks to recover, or it might trigger too late relative to what the position is actually worth.
The correct approach: define the stop based on the cost to close the options position itself.
The Standard Iron Condor Stop Loss Method
For iron condors, the widely used standard is:
Close when the cost to buy back the spread reaches 2× the credit received
Example:
- Iron condor sold for $1.50 net credit
- Stop loss triggered when the position can be closed for $3.00
This approach:
- Is directly tied to the P&L of the position (not the underlying price)
- Limits losses to approximately $1.50 per share ($150 per contract) before commissions
- Is consistent regardless of which side (put or call) causes the loss
Position-Level vs. Spread-Level Stops
For an iron condor (four legs combined), monitor the total cost to close the entire spread. Some traders apply stops separately to the put side and call side — closing the threatened side while leaving the unaffected side open. Both approaches are valid; the combined approach is simpler for automated execution.
GTC (Good-Till-Cancelled) Exit Orders
Once you open an iron condor, placing a GTC buy-to-close order at the profit target price lets the broker execute the exit automatically when the market reaches that level. A separate GTC or conditional order at the stop loss price provides the same automatic exit on the downside.
In fully automated strategies, both exits are managed by the platform without requiring manual GTC order placement.
How Automated Stop Losses Work
Tradematic applies stop loss rules automatically on every iron condor position. The platform monitors the current cost to close each position relative to the original credit received and executes a buyback order when the configured stop loss threshold is reached.
This removes the most common failure in manual stop loss execution: hesitating to close a losing position because you believe it will recover. The automated stop executes at the defined threshold, every time.

Conclusion
Stop losses for options trades are defined based on the cost to close the position — not the underlying asset's price. The standard for iron condors is closing when the buyback cost reaches 2× the credit received. Automated platforms apply this consistently on every position, eliminating the hesitation that makes manual stop loss execution unreliable.
