I have traded JNUG, JDST and recently started trading TECS and TECL for over 3 years filling orders 2 to 3 times per week. I find these 3X ETF quite mentally stimulating. I have studied these ETF's quite extensively and all of the supporting charts and graphs for how these types of products perform. I think education on how settled and unsettled funds work should be mandatory for any one seeking to trade stock. Also all trading platforms should offer a basic charting course that all new traders would be required to complete before being allowed to place their first trade.
