Do bond traders accept mobile phones?

Fund securities companies, involving trading positions and their own research positions, as well as fund managers, need to hand in their mobile phones at the opening.

Bond is a kind of financial contract, which is a creditor's right and debt certificate issued to investors when the government, financial institutions and industrial and commercial enterprises directly borrow money from the society and promise to pay interest at a certain interest rate and repay the principal according to the agreed conditions. The essence of a bond is a certificate of debt, which has legal effect. There is a creditor-debtor relationship between bond buyers or investors and issuers. Bond issuers are debtors and investors (bond buyers) are creditors.
