We increased the security of the trading API (anti-replay protection). For Private REST Methods, the mechanism for signing requests will be changed. To ensure their integrity and authenticity, each request must include an arbitrary unique

nonce. At the end of the transition period, processing requests without
nonce will stop. The transition period ends on May 19, 2021.
