The broker changed the overnight fee from 0.075 to $30 per share and multiplied by 3 on Wednesday and burned the account. I sent e-mail for inquiry, but the complaint was not replied. For example, the stock I bought with the code MRCK.U from November 26 to December 2 which is 6 days, but the value difference of the overnight fee is exceeded $300 after changes. After the adjustment causes a burn, the platform is adjusted back to the original level. However, the negative value caused by overnight cannot be changed back
