DCA SPY/IVV made investment easy.

forget about all the noises, politics, or economy...  

looking back, all the stop loss became stop gain.  that's why I never use stop order for IVV.  stop order is only for individual stock.

what do investors really need to trade/invest then?  SIMPLE DCA with FOCUS and PATIENCE!  其他， 都是瞎忙。
