A DNE request prevents the automatic exercise of ITM options. This is helpful if your account lacks sufficient buying power to support the exercise. To submit a DNE request, email support@heygotrade.com before the following times, depending on the season in the US:
When Daylight Saving Time (DST) is in effect (approximately March–November):
Send the email before 01:00 WIB (early morning) on the expiration date.
When DST is not in effect (approximately November–March):
Send the email before 02:00 WIB (early morning) on the expiration date.
If the options have value, it is generally better to sell them to capture their value rather than submitting a DNE request.
