You know the feeling. The setup lines up exactly how you drew it. The stock fades right into your level, you put on a third of your size, and then the move happens without you. You read it correctly and still barely made anything, because the position was too small to matter.
The problem usually is not your read. It is your size, and specifically when you add it. That is the gap the 30/70 rule is built to close, and it is one of the first things we drill into members who keep getting the direction right and the paycheck wrong.
What the 30/70 rule actually says
Cap the front side of a move at 30% of your intended size. That is your feeler. Whether you scale it in over a few clips or take it in one, no more than 30% goes on before the trade proves itself. The other 70% goes on at confirmation, once the stock shows you the move is real.
On a short, confirmation is the backside coming in. The stock pushes into resistance, rolls over, prints the death candle on heavy volume, and starts trading back below VWAP. Look at the chart. The green zone on the left is the front side, where price is still grinding into resistance. The red zone is the backside, after the top is set. Your first 30% can work in the green. The rest goes on once you are in the red and the move is confirmed, and that is also where your stop moves to a level above the high that covers your full position.
That single split, 30 before and 70 after, is what keeps a feeler from quietly turning into a full-size bag on a stock that refuses to quit running. It also fixes the opposite mistake, the one where you are full size on a broken stock that has not actually proven anything yet. We saw a guy do exactly that recently, full size on a faded stock that bounces maybe one time in twenty or thirty. If you want to play that side, learn how to scale into broken stocks on the short side instead of loading up before the chart agrees with you.
Why most traders never add the other 70%
Here is where it falls apart for almost everyone. People love the 30%. It is safe. The feeler rarely hurts. So they keep their loss small on the front side, the trade turns, and then they panic and scalp out because all they wanted was to make the money back as fast as possible. Small win, small loss, small win, then a random huge loss that wipes the slate. That is the loop. We have lived in it ourselves for years.
If all you ever deploy is 30%, your winners will never be big enough to cover your losers. The bulk of your money comes from the 70%. The only thing standing between you and that size is confidence in the setup, and if you cannot bring yourself to add, you do not trust the read yet.
That is not a sizing problem. It is a preparation problem, and the fix is screen time. The charting we teach is simple on purpose. A backside is not hard to recognize once you have studied a few hundred of them. You learn to see when momentum has shifted, when the longs are done, when the top is set. Once you have backtested a setup enough to know how much range it gives you on the backside and roughly what it pays when it works, adding the rest of your size stops feeling like a leap and starts feeling like the obvious next click. Until you have put in that work, you will keep freezing at the exact moment you should be sizing in. This is also why becoming a consistently profitable trader takes the time it takes. The competence has to come before the size.
Find consistency in your losses
The thing that makes the 70% possible is knowing exactly what you will lose if you are wrong.
Set a max stop loss with auto liquidation at your broker. Base the stop on the chart, at the level where your thesis is broken. Then build the habit of keeping your losses roughly the same dollar amount, all within about a hundred bucks of each other to account for slippage. That sounds like a small thing. It is not.
Think about the math. If you lose a thousand dollars on the way into a position but your average winner is only five or six hundred, you will never have the stomach to hold the next trade through to the area where you should exit. Your losses are bigger than your wins, so every green trade gets scalped early out of fear. Flip it around. Once your losses are consistent and capped, you can use whatever size the setup calls for, because the downside is fixed no matter what. You could put on fifty thousand shares and still know your loss to the dollar, because the hard stop sits at the level you chose. If you are using big size and not using a hard stop, it is hard to say what you are even doing.
Members tell us this is the single change that pulled them out of the wild P&L swings, the days that were either great or a disaster with nothing in between. Risk management is what turns the size from terrifying into routine.
Scaling, scalping, and piking are not the same thing
These three get blurred together constantly, and the confusion costs people money.
Scalping, the way we mean it, is trading line to line. You go from support to resistance, and you take what the range gives you. Sometimes that is ten cents. Most of the time it is thirty or forty. That is Bao’s bread and butter, and it is a real strategy with a real edge, not the thing people on Twitter call scalping where they grab five cents and bail again and again.
Scaling is something else. It means building a position in pieces toward an average you have planned. Bao does this well with smaller bullets, scaling in and, just as importantly, scaling out, always knowing where his average sits and where he stops. Honestly, scaling was designed to solve a FOMO problem. People were getting in twenty cents below their level, watching the projection come, and then crying about a bad average. Scaling smooths that out. But if you do not have a FOMO problem and you are willing to wait, the simpler move is to put your size where you actually think the stock turns, add when you are proven right, and sell into the pop.
That is the role of anticipation size. Say you think a level is going to reject. It is fine to put a little on before it happens, your feeler, your 30%. Then when the move confirms, you add the rest. The mistake is going full size on the anticipation bullet before the stock has proven anything. Every trade needs a thesis you can defend, and the best way to size with conviction is to build a trade thesis first, then let the size follow the idea.
Piking is the failure mode. A piker covers a position way too early, not because the plan said to, but because the confidence was never there. If you scale into a clean setup and then scalp right back out of it for a tiny gain, that is a confidence leak, not a strategy.
Leave a little on for the runner
Covering too fast is one of the most common things members work through, and it is worth pulling apart, because there is a real tension here.
If the stock hits your support level, you get out. There is a reason we preach nail it and bail. Most of the time, when price reaches a support level, it bounces from there, so taking the money and walking is the right call ninety-nine times out of a hundred when you have nailed the move.
But if your goal is to grow your P&L, you do not have to take all of it off at once. A few approaches work well. Cover the bulk of your position at your planned exit, then leave a quarter on for the home run and let it ride as far as it goes. That is how Austin tends to do it, and the beauty is that he is not shooting for the home run, he just leaves the door open for one. Another version is to cover just enough to pay for your loss if the rest goes against you, which turns the remaining position into a free roll on a break-even trade. There is even a trick a few guys use, a small FOMO cover button on the hotkeys. If you are in a thousand shares, that button might take off only a hundred. Weirdly, our brains read that tiny cover as relief from the fear of giving it all back, and it lets you hold the rest for the actual move.
This is a muscle, not a personality trait. Start small. If you trade a thousand shares, leave a hundred on, then a hundred and fifty, then two-fifty as it gets comfortable. It is a reflex you train, and that little extra profit adds up to cover the small losses you take elsewhere.
One discipline that pairs with this is the 10:30 rule. A lot of the morning direction is set early, and stocks that are going to run tend to show it before 10:30. If you have a busy job and cannot babysit a position all day, set your line, see what the open does, take your move, and be done. There is nothing wrong with a clean morning trade if that fits your life and your head.
Master scalping before you try to hold
Everyone wants to be the trader holding the eight-dollar runner from four-sixty. Almost nobody wants to do the part that earns it.
Scalping is how you build the account and the experience to eventually hold longer. You start at level one. You scalp, you grow the account, you learn things about the market and about yourself, and you find your personality as a trader. Maybe you turn out to be a VWAP-projection short on higher-float names, where the thicker float makes the fade easier to control, like putting your hand in a peanut butter jar instead of a glass of water. You do not know yet, and that is fine.
When you miss a runner, do not beat yourself up over it. If you have true edge in a holding strategy, you would have piked ten or twenty of those in a row, not one. Missing a single stock that ran to eight bucks while every other trade that week was a clean, correct scalp is not a problem. But if you start tracking your scalps and notice that one after another keeps running well past where you got out, twenty or thirty times in a row, then you have evidence, and that is when holding longer makes sense. Let the data tell you when to expand, not your ego.
When the market is not yours, do not force it
Slow stretches are part of this. One January is great, the next February is a grind, the small caps go quiet, the setups thin out, and the few that show up are expensive to locate. That is when traders go looking for action in names that are not theirs, posting charts of large caps they have no business in, revenge-trading a ticker that has burned them twice already.
You are almost always better off shutting it down. Set parameters and hold the line on them. We will not short something that is not up at least 30%, and even then we want a new high of day, because without range there is nothing to trade. The cost of forcing it is not just the losses. It is mental capital. Burn through that over a slow month and you will be exhausted and foggy by the time the market heats back up and it is finally your turn. Protecting your head during the dead stretches is how you show up fresh when the moves come back.
So the next time a setup lines up and you feel that pause before adding, ask yourself which problem you actually have. If you do not trust the setup, go back to the charts. If you do trust it, the stop is set, and you know your loss to the dollar, then there is no reason to leave 70% of the trade on the table.
