Which of the following is a general rule for trading futures?

Due to the fact that markets only trend 30% of the time, 100% of capital should be invested at all times

The majority of capital should be committed to the strongest market since it is rare that more than two or more markets will experience a major move simultaneously

Total amount risked on any single trade should not exceed 5% of equity

At least 50% of total equity should be dedicated to the market group with the strongest trend
