Params:
event - Tick data we parse through to determine if we want to create a strangle for the strategy.
Required:
optCallDelta: Optimal delta for call, usually around 16 delta.
maxCallDelta: Max delta for call, usually around 30 delta.
optPutDelta: Optimal delta for put, usually around 16 delta.
maxPutDelta: Max delta for put, usually around 30 delta.
Optional:
expCycle: Specifies if we want to do monthly ('m'); unspecified means we can do weekly, quarterly, etc.
optimalDTE: Optimal number of days before expiration to put on strategy.
minimumDTE: Minimum number of days before expiration to put on strategy.
roc: Minimal return on capital for overall trade as a decimal (not handled).
minDaysToEarnings: Minimum number of days to put on trade before earnings (not handled).
minCredit: Minimum credit to collect on overall trade (not handled).
maxBidAsk: Maximum price to allow between bid and ask prices of option (for any strike or put/call).
minDaysSinceEarnings: Minimum number of days to wait after last earnings before putting on strategy (not handled).
minIVR: Minimum implied volatility rank needed to put on strategy (not handled).
We go through each option in the option chain and find all of the options that meet the criteria. If there
are multiple options that meet the criteria, we choose the first one, but we could use some other type of
rule for choosing.
