Personally I was starting from 100 euro deposit. Really I do not recommend anyone to try trading with such small amounts. You should have experience in this otherwise it’s to risky. Optimal starting trading deposit should be at least 1 000 eur or usd. In this case your trading lot should be 0.01 lot and maximum positions size to one direction not more then 0.1 lot
In order to start trading you should carefully select broker company or bank where you will open your trading account because if you will use offshore brokers – they may disappear with all your money. Other reason why many traders use broker companies – they simply do not want to pay income tax.
