Because Greek values generally change slowly and updating them takes a lot of processing time, CQG IC offers you the opportunity to set optimal update frequencies based on your preferences.
Update Frequency settings allow you to set the refresh period for average volatility, interest rate, and new/removed contract and to set update delays for theoretical value and the geeks.
These preference do not apply to Options Calculator.
