I was bookmarking a link to a site that determined the potential profit / loss of an options trade. I lost the link when I bought my new laptop and the bookmarks did not transfer. Does anyone have it ? Thanks
You should be able to visualize the profit / loss of an options trade in your head - no need for some sort of online calculator.
I usually just look at the maximum loss which is usually calculated for me by my broker every time before I submit the order. If it's acceptable to me, I submit the order, otherwise I don't. Profit, unless you are shorting the option, is whatever the market can and will give you. You won't know that anyway and I don't bother to calculate it beforehand.
Your broker should have the tools to easily graph the trade. But here is a very easy to use grapher: https://optioncreator.com/
