Questions about futures markets....Please help

[rusty JEDI]

I was taking a look at wsex, in particular futures.

I ran a search for the last 6 months in this forum about futures but couldnt find any info. I think i understand how bid and offer works. Buy at offer and sell at bid.

1. Are you always able to sell at bid as many holdings as you would like. I know that bid can go to 0 and then all your holdings are worthless. But if you had an insane amount could you sell at the bid price any amount of holdings for that listed bid price?

2. I see for stanley cup futures the spread between bid and offer is like 20-25, or 16-20, then 12-15. So the lower it gets the closer the bid and offer become. This spread is where the site makes its money, but are these fair spread amounts? Is there a better futures site?

3. Any tips on futures? Is there no talk about them here because they are in general not worth while?

4. Is there anything else i need to know?

Thanks
