Fundamental truths and haiku

[Karmasaur]

I know, right.

I just wondered if I needed the 7 grand to buy the shares so I could sell them a minute later for 8 grand,.....or if I merely dealt with the contract cost and profit (or loss of contract investment) and the actual buying of the shares and subsequent selling of the shares was done without the need for my 7 grand.

But thanks anyway,.....
