Why do you want to donate your money just like that?
As I see it, you have two options:
1) Lose those $2500 as you most likely will. Then save up a new minimum stake of $2500 and lose them all over again. Perhaps you give up after the first or second time, or perhaps you spend the next years running in circles opening accounts that are doomed to fail in the first place.
2) Spend your time reading, studying the markets, writing a trading plan, etc, while saving up sufficient capital so that you really have a chance of making it.
I have been told that $10 000 is a bare minimum. Personally I will not open an account until I have at least $30 000 to deposit.
Some things to think about:
How much is commissions on a $2500 account compared to a $30,000 account?
How much in percentage of the account is a $100-200 loss if you compare the small and the big account?
How many losers (yes, losing even though smart losing is inevitable even with the pros) can you take in a row in order to fullfill the expectancy of your system (you have one right?)?
Do it right the first time and make the best use of your time and efforts.
Good luck!
