If you've tested out your strategies in paper 'simulated' trading, and you're looking to add money to your trading account so you can begin 'real' trading, you'll need to identify the procedure that your broker requires for adding money to your account. There are typically several ways to do this, with an ACH, a wire, mailing in a check, etc., depending on what your broker offers.
This is between you and your broker, and we suggest that you contact your broker to get the details on how this is done. It might require obtaining the broker's ABA number or other numbers needed to set up an ACH or other type of transfer. Make sure you understand the timing requirements and costs associated with transferring funds to or from your broker. as some transfer methods take longer than others and can vary in cost - though many offer ways to transfer funds to your brokerage account for free.
