This rule comes straight from Jack Schwager's Market Wizards, the interviews with America's greatest traders, and it names one of the most insidious dangers in the whole business — because it disguises itself as enthusiasm. Trading delivers a genuine chemical hit. The position is on, the price is moving, your money is live, and your body floods with adrenaline. It feels exciting. It feels like being alive. And that feeling is exactly the problem, because it is, quite literally, a drug — and a trader can become an addict as surely as any other kind of junkie.
The rule is therefore simple to state and hard to live by: don't be a junkie trader.
The pit and the fix
Think back to the floor traders of the old days — the men in the trading pits of the nineties, shouting and signalling, swept up in the roar of the open outcry market. Market Wizards is full of that world, and it captures something important about it: the pit was thrilling, and the thrill was addictive. For many of those traders, being in the market stopped being a means to make money and became an end in itself. They needed to be in. The action was the fix, and they could not stand to be out of it.
That is the junkie trader, and the screen-based version of him is alive and well today. He is not in the market because his homework found a good trade. He is in the market because he cannot bear not to be — because flat feels like withdrawal. He opens positions to feel something, scratches the itch with a trade whenever the boredom builds, and mistakes his own restlessness for opportunity. He will tell you he loves trading. What he loves is the adrenaline, and the trading is just how he gets it.
The cruel twist: the fix doesn't need a win
Here is the part that makes this addiction so uniquely destructive, and it is the heart of the rule. The adrenaline rush does not depend on the trade going well. In fact, the rush is often bigger when the market runs against you.
Think about it. When a position is quietly working in your favour, it is almost calm — pleasant, but not electric. But when the market is moving hard against you, when the loss is mounting and your heart is pounding and everything is on the line — that is the biggest hit of all. The fear, the stakes, the desperate hope of a turn: it is the most intense feeling the screen can give you. And this is catastrophic, because it means the junkie trader's reward is completely decoupled from his profit. He gets his fix whether he wins or loses — and he gets the strongest fix from the losing trades that are destroying his account.
Sit with that, because it inverts everything. A normal activity punishes you when it goes badly, and the pain teaches you to stop. But the trading addict is rewarded by his worst trades — they give him the most adrenaline. The feedback that should make him quit a losing position instead makes him feel most alive in it. This is why the compulsion is so ruinous and so hard to break: the very experiences that are emptying his account are the ones his brain is chasing. He is not trading to make money. He is trading to feel the rush, and the rush and the money have come completely apart.
The quiet bleed of overtrading
Even when it does not blow up dramatically, the junkie's habit drains him steadily through sheer overtrading. Because he needs to be in the market, he manufactures trades that are not there — entering on thin reasons, on setups that do not really qualify, on pure restlessness. Every one of those unnecessary trades carries a cost: the spread, the commission, the financing, and the simple statistical drag of taking positions with no real edge. Trade for the sake of trading and you pay the broker a toll on each one while gaining nothing in return. The account does not die in a single crash; it bleeds out a few points at a time, trade after pointless trade, until there is nothing left and the trader genuinely cannot understand where it went.
This is the exact opposite of the patience that Rule No. 7 demanded. The chaser ran after a specific move out of frustration; the junkie is worse, because he doesn't even need a move to chase — he just needs to be in, on anything, all the time.
Wait for the market to speak
So what is the cure? It is the same discipline that runs through the whole second half of these rules, applied to the deepest layer of the problem: you do not need to be in the market.
You wait until the market gives you a signal. And if you have done your homework — if you have a plan and you know the setups you are waiting for — then the market really does, in a sense, talk to you. It shows you the level, the pattern, the moment your plan was built for, and it says: now. You are not inventing trades to feed a craving; you are waiting, patiently and without action, until the market itself tells you the conditions you defined have arrived. Until then, you sit. You may do nothing for four or five hours — no position, no action, no fix — and that stillness is not failure. It is the discipline working exactly as it should. Then the signal comes, and then you trade.
The junkie cannot do this, because the waiting is precisely what he cannot tolerate. Learning to sit flat and calm, feeling no compulsion to act, is therefore not just a trading skill — it is the direct antidote to the addiction. The trader who is comfortable doing nothing has already won the fight that the junkie loses every single day.
Trade for money, not for feeling
Underneath it all is a single mental shift. The professional trades to make money. The junkie trades to feel something. Get those two motives straight and most of the problem dissolves.
This is why the great traders so often describe good trading as boring — and why, if you find your trading thrilling, that is a warning sign rather than a badge of honour. Excitement in trading usually means you are overexposed, overtrading, or gambling, none of which is sustainable. The aim is not to feel the rush; the aim is to execute a sound process calmly and let the results accumulate over time. If you need excitement and adrenaline in your life — and most people do — find it somewhere that is not your trading account. Get it from sport, from the mountains, from anything where the thrill does not cost you your capital. Keep the need for stimulation entirely separate from the business of trading, because the moment the two mix, the feeling starts making your decisions, and feelings are the worst trader you could possibly hire.
It is worth being honest, too, that for some people this crosses from a bad habit into a genuine addiction, indistinguishable from gambling addiction in how it works on the brain. If you recognise that the action itself has become the point — if you cannot stop even when it hurts you — that is something to take seriously and, if needed, to seek real help with. There is no trading edge worth that.
The bottom line
Don't be a junkie trader. Trading delivers a real adrenaline rush, the rush behaves like a drug, and the cruellest part is that the biggest hit comes from your worst, losing trades — so the addiction rewards exactly the behaviour that ruins you. You do not need to be in the market. Wait, calmly and without compulsion, until the market gives you the signal your homework taught you to recognise, even if that means hours of doing nothing. Trade to make money, not to feel alive. And if you ever catch yourself entering a position just to feel the kick, close the screen — that is not a trader at work. That is a junkie looking for a fix.
