Quote from NoDoji:
I am only beginning this plan of adding to winners, so I don't have the "live" experience yet. I have manual back testing experience. My tactic of initiating on a pullback and adding on a breakout is one of many scaling tactics. If I get into a trend off an early reversal signal, and the reversal breakout confirmation move is strong, I think I'd consider holding through the pullbacks and adding at those points.
Size on breakouts is not a place I can yet provide feedback, because I've only traded 1 lot on breakouts, and have gotten significant slippage when the breakout is strong. BUT if you have a nice profit cushion from the initial position, and the trend is early or midstream (or ridiculous as in "There's no way this can go any higher/lower!"), I'm thinking size is the right thing to do. Some of these breakouts lately have run 50 ticks out of the gate.
I know there are counter-trend traders and faders who average down and make a great living trading. I find it too stressful and too dangerous when I have a small trading account and have to produce consistent significant returns off it.
This post pretty much sums it up for those who average down without a position size/risk management plan set in stone and known in advance.
The biggest problem is that MOST of the time you CAN average your way out of trouble, thereby having a 90% or better win rate which satisfies your ego because you're never wrong. This conditions you to believe that price always does a certain thing if you're patient enough.
Dejavu informed us not long ago that mathematically speaking price reverts to the 20-period moving average 100% of the time. I'm pretty sure it does because on every chart I've seen it does indeed.
But it's a MOVING average, and by the time price finally gets back to it, it may have moved very far from where it was when you first began fading what you calculated to be an "extreme", and by then you may be out of bullets and in deep trouble. I believe Dejavu had a 100% win rate for a few months and stopped posting the day we had a massive trend that ran all the way into the close. The moving average was well over a point from the initial signal to begin fading the first extreme move and the pullbacks were shallow. A trader who can't take a small loss because s/he conditioned to believe the 100% win rate will never fail as long as s/he keeps averaging, will suddenly have that day that wipes out weeks, months or years of profits.
