Do not over trade. One of the most common mistakes that traders make is leveraging their account too high by trading much larger sizes than their account should prudently trade. Leverage is a double-edged sword. Just because one lot (100,000 units) of currency only requires $1000 as a minimum margin deposit, it does not mean that a trader with $5000 in his account should be able to trade 5 lots. One lot is $100,000 and should be treated as a $100,000 investment and not the $1000 put up as margin. Most traders analyze the charts correctly and place sensible trades, yet they tend to over leverage themselves. As a consequence of this, they are often forced to exit a position at the wrong time. A good rule of thumb is to never use more than 10% of your account at any given time.
