What's is the advantage of trading with 100:1 or 200:1. My live currency acct is 100:1 leverage, my commodities acct is 200:1. I trade 0.3 lots with the 100:1 which cost me $300 per trade. What would be the advantage of moving up to 200:1? Can't I just do 0.6 lots with 100:1 leverage. What's the advantage here? Thanks!
