If that's your style fine. I only mentioned not holding overnight as 99% of the individual traders here avoid doing so, with one of the main reasons being the effect other markets have on the Nikkei.As a swing trader I hold over night - sometimes for weeks at a time -one time for over 2 months. I would not hold without having a decent profit and a stop loss. Its not that wild of a ride. The day I am afraid to hold overnight is the day I should quit trading. Gaps? There last one was June 2015 - no worse than our ES.
