Hi! I didn't found in the Internet who (institution or person or whatever) create the different strike prices on a stock. Why some have lot of strike prices, and others only a couple of them. Do you know some information source to read about this?
Ah, I see, so if a stock is on Nasdaq, is the Nasdaq who create the options... Is there some rules for that? Why some stocks in very low prices (less than 2$) have options and others not?
The exchanges. They create rules: i.e. for stocks under $50 strikes are spaced $1 for the front and back months. for next months they are spaced $5 For stocks over $50 strikes, they are spaced $5 for front and back months, $10 for next months, etc. They publish the rules.
