Coinbase Pro Market Structure Update

On Friday, March 22 @ 6:00 pm PDT, Coinbase Pro will implement a set of changes to further optimize the market health of our platform. These changes are designed to increase liquidity, enable better price discovery for trades, and to make price movements smoother. This will lead to a more efficient market and increase trading opportunities for all of our customers. The changes include:

1. New fee structure that is designed to increase liquidity by reducing the delta between maker and taker fees

2. Updated order maximums designed to help protect customers from large price movements

3. New order increment (“tick”) sizes aimed at improving market structure

4. Turning off stop market orders

5. Adding market order protection points

New Fee Schedule

The calculation for volume tiers will continue to be based off trailing 30 day volume. You can also see your trailing 30 day volume within Pro.

Updated Order Maximums

We periodically review our maximum order size, which is designed to mitigate the impact of large orders on market liquidity. The latest order maximums can be found on our markets summary page.

Updated Tick Sizes

The tick size of a market is the minimum increment between orders. We will be decreasing the tick size on the following 5 books: ETC-USD, ETC-EUR, ETC-GBP, LTC-BTC, ETC-BTC

The latest tick sizes for all products can be found on our markets summary.

Deprecating Stop Market Orders

Coinbase Pro and Prime will no longer support stop market orders. All stop orders must now be submitted as limit orders and include a limit price. All currently open stop market orders will be canceled on Friday, March 22 @ 6:00 pm PDT.

Adding Market Order Protection Points

Coinbase Pro and Prime will introduce a 10% market protection point for all market orders. Market orders that move the price in excess of 10% will stop executing and return a partial fill. For example: a market buy submitted when the last trade price is $4,000 will only fill at price levels below $4,400. Protection points help prevent large orders from causing more than 10% slippage.

Scheduled Downtime

Coinbase Pro will be offline Friday, March 22 @ 6:00 pm PDT to 6:30 pm PDT. Please subscribe to the Coinbase Pro Status Page to receive updates on the market closing and re-openings.
