Hi! I want to share this with you (from longtermtrading.com), it is one benefit of long term trading which combines the use of long term and short term trading:
Long Term Trading Can Provide Additional Diversification for Shorter
Almost every trader understands the importance of diversifying trading across many different commodities. Some larger advanced traders even diversify across trading systems. For instance, one may use a breakout trend following system in conjunction with a system designed to function in consolidating markets. Few traders, however, are adequately diversified across different trading time frames. For instance, if you normally trade short term swings of 1-5 days or day trade, the long-term approach to trading can provide a unique element of diversification not found in other shorter term trading systems. This diversification can increase overall trading profits while reducing drawdown on an absolute dollar and percentage basis.
