If your Groww Balance is negative, then the following charges will apply:
Every day: Delayed payment charges (DPC) of 0.045% + GST will be added for each day it stays negative.
After 5 working days: Your pledged facility will be blocked if it continues to be negative for more than 5 consecutive trading days.
After 7 working days: Your pledged shares will be liquidated to recover the amount if your Groww Balance continues to be negative for 7 consecutive trading days.
To avoid this, add money to your Groww balance before the end of the day and ensure it's not negative.
