Trader Slang, Explained: 20 Terms Beginners Get Wrong

Trading has its own vocabulary, and a lot of it is jargon wrapped around a fairly simple idea. The problem isn't that the words are hard. It's that people pick them up from group chats, use them slightly wrong, and then make decisions based on a definition they never checked.

Here are 20 you'll hear constantly.

Positions and direction

Long. You own it and you profit if the price rises. That's all it means. It has nothing to do with how long you hold.

Short. You've borrowed and sold something you don't own, hoping to buy it back cheaper. Your upside is capped, because the price can only fall to zero. Your downside isn't, because there's no ceiling on how high it can go.

Bull and bear. A bull expects prices to rise, a bear expects them to fall. The usual explanation is that bulls attack upwards with their horns and bears swipe downwards. Nobody's certain that's the real origin, but it's the one everyone repeats.

Flat. No position. Sitting in cash. Underrated as a choice.

Price behaviour

Dip. A short-term fall inside a longer uptrend. The word does a lot of quiet work, because whether a fall is a dip or the beginning of something worse is only knowable afterwards. We wrote about that here.

Dead cat bounce. A brief recovery inside a serious decline that fools people into thinking the worst is over. Grim name, useful concept.

Support and resistance. Price levels where buying or selling has repeatedly shown up before. They aren't laws of physics. They're places where enough people have previously changed their minds that it might happen again.

Breakout. Price moving decisively past one of those levels. Roughly half of them fail and come straight back, which is why the follow-through matters more than the break.

Consolidation. Price moving sideways in a range. Boring, and often where the actual decision gets made.

Gap. When a market opens at a very different price from where it closed. Common after earnings or overnight news.

Risk and mechanics

Stop loss. An order that closes your position automatically at a set price. The point is to make the decision while you're calm rather than while you're losing money.

Stop hunt. A move that pushes just far enough to trigger a cluster of stop losses before reversing. Whether this is deliberate or just what happens when everyone puts stops in the same obvious place is an argument with no ending.

Leverage. Trading with borrowed money. It multiplies gains and losses equally, which people tend to remember in one direction only.

Margin call. Your broker telling you to add funds or have your position closed. Almost always arrives at the worst possible moment, because that's the moment that triggers it.

Liquidity. How easily you can get in or out without moving the price yourself. Thin liquidity is why a small position in an obscure asset can be much harder to exit than it was to enter.

Culture and psychology

Diamond hands. Holding through volatility without selling. Meant as a compliment, though it describes conviction and stubbornness equally well, and only the outcome tells you which one it was.

Paper hands. The opposite. Selling early out of fear. Usually an insult, occasionally just good risk management with bad PR.

HODL. Originally a typo for "hold" in a 2013 bitcoin forum post written by someone who admitted they'd been drinking. It became a philosophy anyway.

Bagholder. Someone still holding an asset well after the rest of the market moved on. Nobody plans to become one.

FOMO. Fear of missing out. The feeling responsible for more bad entries than any indicator ever built.

The three people use most loosely

"Oversold" doesn't mean cheap. It means an indicator crossed a threshold. Things can stay oversold for a very long time while continuing to fall.

"Due for a bounce" isn't analysis. Markets have no memory and no obligation to be fair. A decline doesn't build up recovery the way a spring builds tension.

"Investing" gets used to describe holding a position you originally opened as a two-day trade and refused to close. That's not investing, that's a stop loss you never set. Worth being honest with yourself about which one you're doing.

Why any of this matters

Vocabulary shapes decisions. Call a losing trade an investment and you'll hold it longer. Call selling "paper hands" and you'll talk yourself out of a sensible exit. The words are doing more work than they look like they're doing.
