yes. it's easier. to mimic future, my suggestion1). is to use 1$ for one index point and that's for 1 contract.
2). people can specify the no. of contract they bet...
3). introduce margin requirement.
however, the no. of the contract should 0, someone goes bankruptcy and have to close the position... where, since we are talking about finance, there is always risk with return. you get to know the leverage risk in index future trading....
my two cents...
the no. is for demo. we can discuss the margin/contract.
(more...)
太麻烦了, 还要 margin ??
玩最简单的: 只用说明你要 买还是卖, 多少个 contract,
