if abeginner wants to earn a handsome money then he should start with at least $1000. the more he will invest, the less risk he will face. if a trader invest a capital of like $1000 than i think his lot volume should never exceeds 1-1.5! i think this range of lot volume will help him to trade safely. never go beyond this range. a trader should always bear in mind that proper money management is the only stair to success in forex.
