A cent account is a micro account for trading little quantities of instruments and any deposit you make is converted into US Cent currency hence the name cent account.
if you deposit $1 into a cent account, your account balance will be 100 cents and so forth.
On a cent account, your lot size is limited to maximum of 1,000 units so you cannot trade more than 1,000 units of any instrument.
The reason for this lot size restriction is to manage risk and keep it low, as cent accounts are meant for beginners who just got off using demo accounts and want to try the real thing albeit with minimal risk exposure.
Experts can also use cent accounts to test out high risk strategies while risking little money.
Brokers like HFM, Exness, FBS, Just Markets, Headway & RCG Markets; all offer cent accounts.
