Yes. Coin buying/selling transactions on Indodax can still be done even though the related digital assets are undergoing maintenance. The maintenance process usually only affects the deposit and withdrawal features of digital assets, not trading activities. Members can still place buy or sell orders in the market and trade as usual. However, if you want to withdraw or add digital assets to your account, this cannot be done until the maintenance is complete. Information regarding the estimated maintenance time cannot be informed from the Indodax side. Even though the trading process is still running, it is better to always monitor the related digital assets independently, especially if you plan to make a deposit or withdrawal transaction. Thus, your trading activities will not be disrupted during maintenance.
