**What is the Exchange Validation for Stop-Loss Limit Order?**

As per **Exchange Circular NSE/CM/57613**, for **Stop-Loss Limit Orders**, there are specific validation rules in place. If the difference between the trigger price and the limit price of an SL-Limit Order exceeds the permissible limit, the order will be rejected by the Exchange.

The permissible limits vary based on the stock price as give below:

- When the stock price is more than Rs.50, the difference between the limit price and trigger price cannot exceed 3%.
- When the stock price is less than or equal to Rs.50, the difference between the limit price and trigger price cannot be more than Rs.1.5.

**Example 1 (Stop Loss Buy Order - Stock Price: Below Rs.50)**
