Quote from Dustin:
The notion that averaging down is for losers is absolutely incorrect. For a new trader with no risk management it can be very dangerous, but if you have your rules in place it can be the difference between failure and success. Obviously the usual place for averaging down would be a reversion-to-mean (RTM) trade. I'm not talking about midday news 5-10-20% news spikes, just morning or afternoon unusual buying/selling. When I see an RTM setup (which is where I make most of my $) there's an automatic thought process that happens.
1-How far is this likely to go?
2-How big do I want to be at the max range?
3-If I want to start scaling now what size should I start with?
4-After my initial position if I scale in every 5-10-20c what size do I place if I want to end up with my max size, at my max risk?
I don't cognitively think about these. I'll pull up a chart and in the back of my mind think (ok this may go $1-2 more in the next 1 hour, if that happens I want to have #k shares, if it goes further my max loss is $$k so that would get me out around xx.yy price. If it doesn't go to the extreme price I want to at least have xxxx shares, so I can make yyy to zzzz dollars.) This thought process literally takes a few seconds, and I'll usually already have my first lot. It becomes instinctive once you trust the edge.
Personally my max single RTM loss is around $10k. I hit this only twice this year. Find your comfort level and trade accordingly with rules in place and it won't be a problem. If I couldn't average down I would be working at Burger King right now.
