Hello ThalesR1195,

Thanks for posting tot he forums.

It is difficult to identify specific factors that influence price action on an instrument, but most usually it is dependent on volume. If there are many calls at say, $1002 dollars and not much at $1001 dollars, it would be easy for a market's price to go up from $1000 to $1001. There can also be 100 buyers wanting 1 contract, and one seller with 100 contracts that can essentially "negate" each other, so to speak, so number of buyers is not as important as volume. Lastly, the market price is determined by the exchange directly, and may be able to provide further insight on how their market making works.

Please let me know if I may be of further assistance.
