Contract size changed
On the 18th of August the contract size of several trading assets - AABA [Altaba Inc.], AXP [American Express Co.], SNAP [Snap Inc.], WMT [WAL-MART STORES Inc.], - is going to be changed. The contract size will be standardized to the average 100'000 USD.
Due to these changes, until the 18th of August, these assets work in "Close only" mode, which means that you can work with the open orders, but you cannot open new ones.
From the 18th of August trading will be resumed to normal.
