System Updates – Lot Size Changes

To allow existing orders to support the new lot size granularity, we will be making an update to every order currently active in each market.

To make this update and guarantee correct execution behaviour for the orders during the update, we will be canceling the current orders and booking a replacement via an atomic transaction.

All order parameters will be preserved through the update and users will not see any behavioural differences in order execution or future updates to these orders.

Users will be notified of this cancel/replace transaction through an Execution Report for each order. The cancellation of the original order and the replacement will also be visible to users querying their order history via API or via the Cancelled and Filled Orders widget.

These changes have already been made successfully for all EOS markets. For orders in these markets, users will have seen the behaviour described above and should have already received their Execution Reports for orders.

The final phase of the update, which will allow users to execute orders in the new lots sizes, will take place December 29, 17.30 UTC.
The new lot sizes and price steps will be:
LTC/BTC: lot 10-3 LTC, step 10-7 BTC
LTC/ETH: lot 10-3 LTC, step 10-6 ETH
LTC/USDT: lot 10-3 LTC, step 10-4 USDT
DOGE/BTC: lot 10 DOGE, step 10-10 BTC
DOGE/ETH: lot 10 DOGE, step 10-8 ETH

During the final phase of the update, pairs under maintenance will be unavailable for approximately 5 min. You will not be able to place or cancel orders on these pairs during this short maintenance period. API users might also receive a “2001: Symbol not found” response on these pairs during this period.

Should you not see this behaviour or if you have any questions or concerns – please reach out to our support team.
