There are multiple ways a credit balance can arise in a trading account:
Profits from Closed Trades
When a trader sells a security and earns a profit, the realised gain is added to the account as a credit.
Fund Transfers and Margin Top-Ups
Any direct deposit or fund transfer made by the trader into the account will appear as a credit.
Dividend or Corporate Action Credits
Dividend payouts or corporate actions like rights issues or buybacks, when credited, add to the account balance.
Brokerage Adjustments or Refunds
Occasionally, brokers may refund certain fees or charges, which reflect as credit.
How Credit Balance Is Shown in Daily Trade Statements
Trading platforms generally display credit balance as part of the account summary. It may be labelled as "Cash Available," "Free Balance," or "Ledger Balance." Traders receive this breakdown in contract notes or daily margin reports, helping them track their financial standing. It is essential to differentiate this from the total account value or unrealised profits, as only the credit balance represents funds that are liquid and actionable.
