I have an idea I wish to test that requires knowing at a particular entry time whether the VIX High Of The Day had exceeded some level. It is a binary decision. For example, at 3 pm, if VIX High Of The Day > 30, allow the trade to enter. Note in above example, if the VIX level is greater than 30 at 3 pm, it satisfies the condition. If VIX level is less than 30 at 3 pm, but it had exceeded 30 at some point in time before 3 pm, it STILL satisfies this condition. This usually would be used in combination with some other signal, such as underlying percent move from the previous Close, which currently OO backtester does not have either and I have submitted a separate request for it. Of course, for completeness, VIX Low Of The Day can be added as well and the comparison can be either > or < for either High Of The Day or Low Of The Day, but for my idea to test, I only need VIX High Of The Day to be greater than a specified level to test. I've not seen this anywhere else so OO would be a first if implemented. I believe it may add value as a signal... but unknowable until various tests can be done.
