It's the same as for other stocks, 5 cents for options under 3.00, and 10 cents for options over 3.00.
I thought like this , but if you check for example AAPL , MSFT options chain u will c as low as 1 cent spread between the bid and the ask ...
These are part of the penny pilot program, hence their tick size is 1 penny. Stocks that are not part of the program have regular 5/10 cent tick size.
Thanks mate , could you explain further cuz i chceked many popular stocks and it is 1 cent , Sbux , jpm , c , gs , wmt , rimm ...
