Most trading mistakes trace back to fear or greed. Learn how they show up, why automation helps, and how to keep them from overriding your rules.
Every trader has a plan when the market is closed. The trouble starts when money is moving. Fear and greed are the two emotions that most often turn a good plan into a bad result.
How fear shows up
- Closing winning trades too early "before it comes back".
- Skipping the next valid signal after a few losses.
- Moving entries further away, so you miss the move entirely.
- Refusing to take a loss and hoping instead - fear of being wrong.
How greed shows up
- Raising lot sizes after a winning streak.
- Removing take-profit levels to "let it run" without a plan.
- Adding to losing positions to get back to break-even faster.
- Switching off safety limits because they "cost money last time".
That last one is worth pausing on. A stop loss or drawdown limit will sometimes close a trade that would have recovered. Those are the moments greed remembers. The one time the limit saves the account is easy to forget until it happens.
Why automation helps - and where it doesn't
An Expert Advisor does not feel anything. It will take the tenth signal after nine losses as calmly as the first. That is one of the strongest arguments for algo trading.
But the human is still in control of the settings. The emotional decisions simply move:
- Turning the EA off after a drawdown, just before the recovery.
- Increasing the lot multiplier after a good month.
- Overriding trades by hand because the market "feels wrong".
Practical defences
- Write the rules down before you trade, including when you are allowed to change them (for example only on weekends, only after a review).
- Size small enough that a normal losing streak does not hurt emotionally. If you check the account every five minutes, the size is too big.
- Separate review from trading. Analyse results weekly, not trade by trade.
- Keep a journal of every manual intervention and what happened next. Most traders discover their overrides cost money.
- Use hard limits you cannot casually switch off: a maximum daily loss, a maximum drawdown, a maximum lot size.
The goal is not to feel nothing
You will feel fear and greed. The aim is to build a process where those feelings do not change what you do. Good risk sizing, clear rules and automation are the tools; the discipline to leave them alone is the skill.
