Quote from fseitun:
If your entries were correct from the start, you wouldn't need to average down at all. Since your entries are probably off, you then "cheat" and start averaging down.
Most of the times, averaging down will reward you, this is why it's the most evil of all cheats. It's the DEVIL for me.
Instead of averaging down, you should seriously start to ask yourself why your entries are off and find a way to become more accurate.
Fseitun, I find this to be an extremely valuable post. I am still in the beginner stage as a trader and fight certain demons a lot. I will do very well day trading with strong risk management strategies, then I'll throw in some riskier trades and do well on those, too, even though they may run against me at first. That is very bad, because it causes me to change my rules for risk management on "certain trades", as if certain trades are just so good they don't require risk management. The biggest demon to take me down is the one that says a price is ridiculous and could not possibly get more ridiculous therefore staying in the losing trade is the right thing to do, because surely people will regain their senses and the trade will do what it was supposed to do originally.
I've been drawing up theoretical examples comparing two styles of trading:
1. Cutting losses quickly when a trade fails to do what the setup indicated it should do.
2. Averaging as the trade moves against you, because the setup is so strong that the price MUST eventually retrace some of that move. (Be sure to define "eventually" because as they say "the market can stay irrational longer than you can stay solvent".)
Scenario 1: You short 1000 shares of stock at 20.00 on a fantastic setup, .20 cent stop. The trade moves against you and you're down $200. You see the stock move to an even better short entry price when it stalls at 20.50 and you put on 1000 shares with a .20 cent stop. The stock rallies once more and you're down another $200. The price moves within pennies of the next round number and pulls back a bit, and now the setup is really strong so you put on your full position of 2000 shares at 20.90, .20 cent stop. It's late in the day, the buyers are finally done and the price falls hard to 20.40. You take your $1000 profit, and end the day up $600 overall.
Scenario 2: You short 500 shares of stock at 20.00 on a fantastic setup, no stop because you plan to build into a full 2000 share position if it moves in your favor or against you. The trade moves against you and you add 500 shares at 20.30. The stock moves to 20.50 and stalls, so you add the rest of your intended position (1000 more shares) at 20.50, giving you 2000 shares at an average price of 20.33. The stock suddenly rallies further moving within pennies of the next round number and pulls back a bit, and now the setup is stronger than ever. Do you violate your max position size for the trade and add more here? Let's try it both ways: a) You hold the existing 2000-share position and wait. End of day selloff to 20.40 gives you a net profit of $140. b) You add 1000 more shares at 20.90 for 3000 shares at an an average price of 20.52. End of day selloff to 20.40 gives you a net profit of $360.
OK, this isn't so bad, all trades ended the day profitable, but the safest method of trading ends the day the most profitable. This is a win-win situation.
Now let's assume the setup was not only strong intraday, but even stronger looking on the 30-day chart and the fact that the stock will surely retrace a good part of the move up within a few days convinces you to hold the winning position overnight to catch larger piece of the move.
Next morning you check the stock and it's gapped up to 22.50 in pre-market trading on good news.
Scenario 1: You have 2000 shares at 20.90, now an unrealized loss of $3200.
Scenario 2: You have 3000 shares at an unrealized loss of $5940.
Is there a down side to a strict risk management and re-entry strategy vs. an averaging strategy? I can't seem to find one.
