To be a professional trader, you need to live on trading.
if you have 5k, buy a TV, do not try to invest.
fxinvesta, you are absolutely right on that one.
during the last two years I have lost about -130k on forex, chasing the dream of making money with just 10k accounts. meanwhile I have built a very profitable, sort of stop strategy, which works one and only with accounts larger than 300k. I would even recommend a min of 1 mil. Then, I realized I do not have that kind of money, to trade it. I was very very disappointed and still is, a little. That is how forex works. One needs a shitload of money to trade with little to no anxiety.
Then, few weeks before, I figured out that the DD that was causing my losses (due to margin calls mostly), can be used in my benefit, instead. To make the story short, I am now building a guardian strategy, that guards the major trend strategy, by reducing the DD of the major strategy with over 80% sometimes. And not only that. It gives me the opportunity to cash in the saved 80% DD as an unexpected profit, on the top of the profit of the major strategy.
Sometimes you win, sometimes you... learn.
A system should work with any amount of money, the problem is that work pay off.
If your back testing shows that in the worst situation, must withstand 300 pips against (it's just a number to understand), you must adjust your money management, not more than 50% of the account.
That will give you maximum exposure, if that exposure is very low, you need more money, otherwise you worked 15 hours a day for a few dollars ....
I think an acceptable return is 20% per year.
If you invest 10k, you will earn 2 K in a year, with that money you can not afford even your Internet connection ...
You've got one option, to force the system, which will take you, no doubt, to the bankruptcy.
Nobody tries to be a doctor without going to college, no one tries to put a restaurant with no money, but incredibly, is full of fools, who think they can be traders, by the grace of God ...
And the market feeds on them ....
Risk comes from not knowing what you're doing.
