What is Position?
Crypto Glossary Definition
An single element in a portfolio. The amount of a specific asset that is held.
Why Position Matters
A "position" is simply the size and direction of a trade you're currently holding — being "long" a position means you profit if price rises, being "short" means you profit if it falls.
Position in Practice
A trader convinced that Ethereum is about to break out above a key resistance level opens a long position, buying ETH with the expectation that its price will rise, and if he's right, the value of that position grows along with the price. A different trader, watching the same chart but reading it as an exhaustion pattern near the top of a rally, instead opens a short position through a derivatives exchange, borrowing and selling ETH he doesn't own with the expectation that its price will fall, profiting only if it actually does. Both traders now hold a position, in the simplest sense just the specific amount and direction of an asset each currently has exposure to, but their positions point in opposite directions and carry opposite risk. When ETH's price whipsaws sharply in the following days, first spiking upward then reversing hard, the long trader watches unrealized profit briefly balloon before shrinking back, while the short trader experiences the exact mirror image, temporary unrealized losses before the reversal turns them profitable instead. Neither position becomes a locked-in, realized gain or loss until each trader actually closes it out, a distinction that matters for both risk management and, eventually, tax reporting.
