What is this fee?
The CAT fee is applied by the Financial Industry Regulatory Authority (FINRA) under the Consolidated Audit Trail (CAT) system โ a U.S. regulatory program that tracks all stock trades to help protect investors and ensure market transparency.
This fee has been in effect since April 1, 2025 and is implemented to cover the costs of maintaining the CAT system. It applies to each U.S. equity trade executed through our platform. In compliance with regulations, this charge is passed on to customers and is reflected in your trade confirmation documents.
How much is this fee?
Equities (NMS) | $0.000035 per share | 1:1 ratio |
Equities (OTC) | $0.000035 per share | 1:0.01 ratio |
Rounded up to the nearest whole share and to the nearest penny.
Examples of Fee Calculation:
If you execute a trade for 1,000 shares in the normal market:
1,000 ร $0.000035 = $0.035 (approximately 3.5 cents)
If you execute a trade for 1,000 shares in the OTC market:
1,000 * 0.01 (ratio applied) = 10 * 0.000035 = $0.00035 (0.035 cents, less than 1 cent)
