You can receive alerts when the bid or ask price of a contract is below or above a certain price according to your settings.
Please note that if you don’t subscribe to OPRA (Real Time Options) Market Data, the alert still can be triggered based on the real-time price, but you can only view the delayed options quotes when you check the options quotes.
You can set the Volume Alert. You will be alerted when the volume is higher than the number of you set.

In addition, if you don’t want to be reminded several times in a day, you can also set the frequency to ensure that you are not disturbed by the alert message.
