Most folks have a day job to cover the essentials of life… like food. When you have to be at a job during market hours, it requires a bit more scrutiny; but, it CAN BE DONE.
Trade/Invest in Longer Bases. Trade stocks or ETFs that tend to trend. Steer clear of wild, whippy stocks (e.g. AMZN) While Amazon is a great company, its chart and price action whips around.
Focus on Clean and Simple Chart Patterns. Look for entries that provide tight stops. Pyramid into positions using 50%, 30% & 20%.
