Long and Short

Two words come up constantly in markets: long and short. They describe the direction of your exposure — which way price has to move for a position to gain or lose. Everything else builds on this, so it's worth getting exactly right.

Long: the familiar direction

Being long is what most people already picture as "investing". You buy something, you own it, and you gain if its price rises and lose if it falls. Buy at 100, price goes to 120, you're up 20 per unit; price goes to 80, you're down 20.

The defining feature of a long position: your downside is bounded. The most an asset's price can fall to is zero, so the most you can lose on a long is what you put in. Painful, but finite. Your upside is open-ended — there's no ceiling on how high a price can go.

Short: the mirror image

Being short is the reverse: it's a position that gains when price falls and loses when price rises. The mechanism is less intuitive because you're selling something first.

In the classic form, to short you borrow the asset (from a broker), sell it at today's price, and now owe it back. If the price later falls, you buy it back cheaper, return it, and keep the difference. If price rose instead, you have to buy it back at the higher price to return it — at a loss. (In practice much shorting is done through derivatives rather than literal borrowing, but the payoff — gain when price falls, lose when it rises — is the same.)

Shorting is simply the tool that lets a position profit from a decline. That is a description of a mechanism, not a suggestion to use it. Nothing here is a recommendation to short anything.

The asymmetry that matters

Long and short are not mirror images when it comes to risk, and this is the single most important thing to understand before the word "short" ever appears in a real decision:

On a long, your loss is capped — price can only fall to zero.
On a short, your loss is unbounded. Price has no upper limit, so there is no ceiling on how far it can rise against you. A short that goes wrong can, in principle, lose more than the position was worth — potentially more than you started with.

That asymmetry is not a detail; it's the defining risk of shorting. It's why short positions demand far more care around sizing and protective stops, and why "I think this will fall" is a completely different proposition, risk-wise, from "I think this will rise." This lesson states that risk as a fact of the mechanism; how to think about position sizing and the risk of ruin is its own subject — see the risk track's Position Sizing and Risk of Ruin.

Long, short, and crypto

You can be long or short many asset classes — equities, FX, commodities, and crypto among them (see Asset Classes). A reminder specific to crypto in Visor: Visor treats crypto as read-only data to analyse, never as something to go and acquire. Describing that a crypto instrument can be looked at long or short is a statement about market mechanics; it is not encouragement to hold, buy, or trade it.

Where Visor fits

Visor doesn't place trades — it's a charting and intelligence workspace, not a broker. "Long" and "short" still matter here because the whole vocabulary of the charts and lessons assumes them: an "uptrend" is the terrain a long-biased reader watches, a "downtrend" the terrain a short-biased one does, and the same candlestick reads differently depending on which side of it you're imagining.
