Leverage for Ripple -  XRPUSD has been changed from 1:100 to 1:50 until further notice from January 3rd, 2021 due to the unstable situation as a result of the SEC filing proceedings against Ripple and its key Directors. 

With the recent volatility in the Silver market, many prominent liquidity providers together with multiple trading platforms are increasing the margin requirements for Silver (XAGUSD).

In order to guard our clients and their funds, the leverage for XAGUSD will be reduced to 1:100 as of market opening time on Thursday the 4th of February
