The Lot Size change for the XBTUSD Swap and XBT Futures we announced last week will be released on Testnet on 31 May 2021 at 04:30 UTC, prior to going into production at 04:30 UTC on 8 June 2021.
We ask that traders take the opportunity to adjust their positions, strategies, and systems before and after the Testnet release to prepare for the Mainnet (production) release.
As a recap, effective 04:30 UTC on 8 June 2021, the Lot Size (or minimum trading unit) on the XBTUSD Swap and XBT futures (XBTM21 and XBTU21) will be amended from 1 contract to 100 contracts.
We expect a 10-second pause in trading starting at 04:30 UTC on 8 June 2021 to apply the Lot Size change, and highly encourage traders to amend open positions and orders to reflect the new Lot Size before the change takes place.
Open orders and open positions that are not adjusted by this time will be affected – please read more about the change here, or take a deep dive into the technical details via our explainer here.
If you have any questions or require additional help, we encourage you to get in touch with our Support team here or email support@bitmex.com.
