Have you ever had this experience?

You buy a stock, and it rises by 10%. You think to yourself, "Wait a bit longer; it can go higher." It rises to 15%, and you are even more reluctant to sell: "Tomorrow it will definitely be higher." Then the next day, the market opens with a sharp drop, and your profit shrinks from 15% to 5%, leaving you with just a small gain. You slap your thigh in regret, saying, "If I had known, I would have sold at 15%!"

Where does the problem lie? It's not that you don't know how to buy; it's that you have a monster living inside you that can never be satisfied—greed.

It makes you unwilling to exit while in profit, always wanting "a little more"; it causes you to treat unrealized gains as your capital and to see pullbacks as an opportunity to add to your position; it transforms your gains into losses, large earnings into small ones.

Greed is the number one culprit in trading that leads to profit erosion.

1. The Nature of Greed: You Always Feel "It's Not Enough"

Greed is not just wanting more; it is "wanting more even when you are satisfied."

You make a 10% profit, and greed says, "Not enough, you can make 20%"; you make 20%, and greed says, "Not enough, doubling is just the starting point"; you double your investment, and greed says, "Not enough, you could have made three times that." It is like an insatiable monster; the more you give it, the more it wants.

The core deception of greed: making you treat "the money you've already made" as "the money you should have made." 

When a stock rises to 15% and you don't sell, then drops back to 10%, you feel like you've "lost 5%". But that 5% was never yours—you were just watching it pass through your account.

Greed gives you the illusion of "ownership" and then makes you suffer when that illusion shatters.

Worse, greed can team up with fear. Greed keeps you from leaving when you're making money, and fear makes you cut losses when there is a pullback.

You originally made 15%, but when it pulls back to 12%, you fear losing the profit and close your position. As soon as you close, the stock price rises to 20%. You get hit from both sides. Greed and fear are the two wheels of the emotional roller coaster for traders.

2. How Does Greed Gradually Eat Away Your Profits?

Let's look at a typical "greed death spiral."

Step 1: Enter the market. You buy based on signals, and the price starts to rise. You're happy with a 5% unrealized gain.

Step 2: Greed kicks in. "Only 5%, still far from my target, let's wait a bit longer." The price rises to 8%, and greed says, "See, I told you it could rise more."

Step 3: Profit erosion. The price falls from 8% to 6%. Greed says, "It's just a normal pullback; don't be afraid." The price continues to fall to 4%. Greed becomes silent, while fear starts speaking: "It's over; profits are disappearing—should we cut losses?"

Step 4: Cut losses or hold on. If fear takes over, you will close your position, making only a 3% profit (or even losing on fees). If you refuse to concede and choose to hold on, the price may continue to fall, turning your unrealized gains into unrealized losses.

Outcome: You could have safely made an 8% profit, but due to greed, you end up making only 3% or even a loss. Greed turns you from "actively taking profits" into "passively cutting losses."

Does this cycle feel familiar to you?

3. How to "Satisfy" the Greed Monster?

It's not about eliminating it, it's about containing it.

You cannot eliminate greed; it is part of human nature. But you can contain it and restrict its movement. The method is: use rules to lock in profits and prevent greed from negotiating.

Method 1: Set "Mandatory Profit-Taking Levels." 

Think ahead before opening a position: how much profit do I want to take from this trade? It can be a fixed percentage (like 10%) or based on technical levels (like previous high resistance levels). Once you hit that level, close it without any "let's wait a little longer."

Set your profit-taking order in advance, allowing the system to execute it, giving yourself no chance to hesitate. Greed might want to say "let's wait," but the system has already closed it for you—greed has no chance to speak.

Method 2:Trailing Stop Loss, Lock in Profits. 

If you don't want to fix your profit-taking but want to hold longer, then use a trailing stop loss. For example, every time the price rises by 2%, move the stop loss up by 1%. This way, your minimum profit will continually increase, and you will never experience "big gains turning into smaller ones."

Greed may still urge you to hold, but the trailing stop loss has already locked in most of your profit.

Method 3: Take Profits in Batches. 

This is a "compromise solution" for dealing with greed. When profits reach your first target (like 5%), sell half your position, letting the other half run. This way, you secure part of your profit while still allowing part of your position to seek higher returns.

Greed will receive a little reward, so it won't force you to hold on. Your mindset will also be steadier.

Method 4: Mandatory Rest After Profit. 

If you have consecutive profitable trades or make a large profit in one trade, greed will be particularly active. At this point, give yourself a "cooling-off period"—no trading that day, or halve your position the next day. Allow the dopamine to decrease and make greed's voice quieter.

A Real Case of "Defeating Greed"

Xiao Huang has been trading forex for three years, and his biggest flaw is "not selling when he’s profitable." He once bought euros and had an unrealized profit of 200 points but eventually lost 50 points due to a stop loss. He regretted it deeply but made the same mistake the next time.

Later, he set a strict rule for himself: every trade must have a trailing stop loss set from the moment he opens the position. For example, after entering, he sets a trailing stop loss 10 points above the entry price. When the price rises by 20 points, the stop loss moves up by 10 points. This way, his profit floor is always increasing. The first time, after the price rose by 100 points and then retraced, his trailing stop loss was triggered at 70 points, and he made 70 points. Although he didn’t get the maximum profit, he was very satisfied because he didn’t have to struggle with "when to exit."

He said, "I used to want to sell at the highest point, but I often ended up selling at the lowest. Now the trailing stop loss helps me make the decision; I no longer have to fight with greed. Even though I don’t always make the most, my profits have become more stable over the long term."

Greed can be "designed away"

Greed is not your enemy; it is your primal instinct.You cannot kill it, but you can bypass it. Use rules, systems, and trailing stop losses to cage it. When you no longer have to choose between "to leave or to stay" each time you make a profit, greed will no longer have a stage to perform.

The greed monster can never be satisfied.But you can deny it opportunities for feeding. Starting today, before every trade, write down your profit-taking rules. Exit if you reach the target; don’t guess if you don’t. Let profits run on their own, and let greed starve itself.
