Ja, some spectacularly bad answers here. For most MT brokers around you need about $100k if you intend to have any chance to make it at all.
The reason is very simple. Regardless of how much leverage you have, most of them have 0.01 lots minimum trade size on 100 000 unit size lots. The brokers that do offer small lot sizes are for the most part not reputable with one notable exception.
To put that into perspective, the value of your trade is : current price x lot size x lots
So in EurUsd at current prices 1.09 x 0.01 x 100 000 = 1090.
If your account has $200 in it, or $500 or even $1000 your minimum trade sizes are far more than the actual value of your account. In fact when you get to $100k only is it about 1%.
Doesn't matter what you're going to do, the account will not survive unless you're one of the top 1% of traders in the world. That's why so many people fail at fx. You're better off taking that money and buying beer with it or watching movies or buy the wife something. Putting a few hundred into fx is just a waste of time and money.
There is one broker that will allow 1 unit trades. Oanda. I suggest opening an account with them and doing a demo till you're happy you can pull it off. Then start with very small trades and up your trade sizes as a percentage of equity as your confidence grows.
Ultimately it's your DD that decides how much money you can make. Not your leverage and not your start amount.
