Repairing the batch helps you place fresh market orders for those stocks/orders that weren't filled.
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 refer to this article or initiate the chat with the chat box option from the bottom right corner or also can mail to firstname.lastname@example.org
