When it's going down is precisely when you should buy.. Thats easy for anyone to do but can be done horribly wrong and have opposite effect than desired.. The key(and most difficult) part is knowing when to buy while others are selling.. figure out When are people going to stop selling and start buying again and at what price this will happen and place your orders near that price before the switch from selling to buying happens on a regular basis then youl get very rich very fast

but if you dont know much/anything about day trading or swing trading dont even try.. the vast majority of people who day/swing trade lose money to the very few who know exactly what they are doing..
