Strategy development is generally done on a forward trading demo account.
Once you believe you have a strategy that works and are comfortable with the results, then I would suggest opening a real account.
When you open the real account, do so with the understanding that the money you deposit, is probably going to be lost because you are moving from a demo to a live account and there may be problems you didn't foresee happening.
New people have a tendency to dump thousands of dollars into an account when they were first starting to trade, and then get extremely upset when they find out they just lost it all on a couple of very bad trades.
Trade only with funds, that are truly disposable, and won't have any negative impact on you.
Never trade with money that you can't afford to lose.
If it looks too good to be true, it's probably a scam! Let the buyer beware.
