Repair
Repairing the batch helps you place fresh market orders for those stocks/orders that weren't filled so your smallcase can be complete. Once you click on 'Repair' from the orders page, you would see a preview of the stocks you're placing fresh orders for. After reviewing this, you can confirm the order.
This will only fix those orders arising due to the following reasons:
You're trying at a point where there's liquidity for the stock
You have added funds to your bank account
If you're unable to repair the batch after trying multiple times, please get in touch with the support team.
