Median should still be OK to use though, as long as you're also including at least twice as many sufficiently long enough TWAPDurations! {% hint style="danger" %} Be careful while using TWAPs in isolation and without aggregation with low time durations; as short term TWAPS can be easily manipulated by bad actors! {% endhint %} ### **Spot Price** TODO ### **Settlement Price** TODO ### **Multiple Prices** TODO ### **Aggregated Price** TODO ### **Safety Considerations** in general, it's better to use an aggregation. e.g. use MAX of spot & recent LTWAPs (60 sec - 60+ mins) while selling calls, but MIN while buying calls; vice-versa for puts -- such that it's "favorable to the party involved". MEDIAN is also a good choice, generally speaking. --- # Agent Instructions This documentation is published with GitBook.
