## buy.AskPrice is the filled price of the long order. Similarly sell.BidPrice is the filled price of the short order.
## Quantity for short order is negative.
## self.Securities[buy.UnderlyingSymbol].Price is the current underlying price.
## Options contracts are for 100 shares, so multiply by 100
## and multiply the number of contracts that will be exercised
