You are ostensibly a trader or an investor. Why would you care if this ends badly? Everyone should be wishing for another '08.
OK come on man... Why would you go long 20 points off ATH. I guess you can average down. You can even have a rule like don't buy when near top bollinger band/don't short bottom and that would save you a lot of money probably. Yes you'll miss a couple of trades but you'll never have this problem again.
I don't wish for my 401k to lose 50% value, for my home price to lose 30-50%, and for my friends and family to lose their job at the expense of a little volatility. We have plenty of volatility right now in the markets.
I'll give you the house, but you know you can sell stuff in your 401k. And if you think this is volatile, doesn't sound like you traded through '08.
