We wanted to provide our customers with an update on Bitcoin Cash (BCH) trading on GDAX.
At 4:00pm PST on December 19, 2017, we launched three BCH order books on GDAX. All BCH order books opened in post-only mode, allowing customers to place open orders and establish liquidity.
At 5:20pm PST, we enabled trading on the BCH-USD book. The BCH-EUR and BCH-BTC books remained in post-only mode.
At 5:22pm PST, we paused trading in the BCH-USD order book due to significant volatility. Once paused, we cancelled resting orders and cleared all BCH order books. We made this decision to ensure a fair and orderly market.
BCH order books will reopen on December 20th at 9:00am PST. All BCH order books will open in post-only mode for a minimum of one hour to establish liquidity. We will continue to closely monitor market activity.
