I'm trying to figure out how my TSLA1 Jan 2019 $30 (originally standard SCTY $30) options are comparing to equivalent standard TSLA options. I expect the spread to be wider since they'll be less heavily traded, so I wanted an idea of how much wider. Here are my best calculations: Does that look correct? The TSLA bid/ask is nicely centered inside the converted TSLA1. Not crazy about the additional $6 spread on either side, but it is what it is. Hopefully by Jan 2019 $6 will be rounding error.
