Frozen balance on Indodax is the amount of digital assets or rupiah that cannot be used temporarily for transactions due to unsuccessful trading activities. When you make a coin buy/sell transaction, a certain amount of funds or digital assets will be frozen until the process is complete. The frozen balance aims to ensure that the funds being processed cannot be used in other transactions. This provides additional security for users. You can see the frozen balance status in your account transaction history either through the Indodax application or website. Or if you want to cancel the trading transaction, please access the following link. After the process is complete, the frozen balance will be available again and can be used for other transactions or withdraw rupiah to a bank account.
