Wallet
A wallet is a digital tool used to store, send, and receive money or digital assets. In finance, it usually refers to a digital wallet, such as Apple Pay or PayPal, or a crypto wallet, which helps users manage cryptocurrencies like Bitcoin or Ethereum.
A digital wallet can be connected to a bank card or hold stored value, allowing users to make payments online, in stores, or through QR codes. A crypto wallet works differently: it does not store coins directly. Instead, it stores the private keys needed to access and manage assets on the blockchain.
Wallets can be custodial, where a third party manages access, or non-custodial, where the user controls their own keys. They can also be hot wallets, connected to the internet, or cold wallets, kept offline for stronger security.
Example:
If you use a mobile wallet to pay for coffee by scanning a QR code, that is a digital wallet in action. If you use MetaMask to send Ethereum, that is a crypto wallet.
In simple terms, a wallet is your digital access point to money, payments, and crypto assets.
Wash sale
A transaction in which a trader sells a financial instrument at a loss and then repurchases it shortly thereafter.
Wash Trading
Wash trading is an illegal form of market manipulation where a trader (or colluding parties) buys and sells the same asset to create a false impression of activity, demand, or price momentum. No real economic change happens, but the market may appear busy or bullish.
It is often called round-trip trading because the trader may end up in the same position, while making the market appear active. Unlike genuine trading, there is no real change in ownership or investment interest.
Wash trading can appear in stocks, commodities, crypto, and even NFTs. It is often linked to market manipulation schemes such as pump-and-dumps, where fake activity draws in real buyers before prices collapse.
Example:
A trader uses two accounts to repeatedly buy and sell a low-volume token. Reported volume surges, other investors assume the asset is gaining momentum, and they start buying. Once the price rises, the manipulator sells for profit.
It’s important not to confuse wash trading with a wash sale. A wash sale is a tax rule involving selling at a loss and rebuying within 30 days. Wash trading, by contrast, is intentional deception and is illegal.
Weak Shorts
Weak shorts are traders who bet that an asset’s price will fall, but they do not have strong confidence in that position. They are usually quick to exit when the market moves against them, especially if the price starts rising.
In simple terms, a weak short is a nervous short seller. They may enter a short trade based on short-term sentiment, rumors, or weak price action, but they often close the trade quickly to avoid larger losses.
Weak shorts matter because their exits can add buying pressure. When short sellers close a position, they must buy back the asset. If many weak shorts do this at the same time, the price can rise sharply and even trigger a short squeeze.
Example:
A trader shorts a stock at $30, expecting it to fall. The company then releases better-than-expected earnings, and the price jumps to $33. Afraid of bigger losses, the trader quickly buys back the stock to close the position.
If many weak shorts do the same, the price may climb even faster.
Wedge
A wedge is a chart pattern in technical analysis where price moves inside two trendlines that gradually come closer together. It shows that the market is consolidating and that pressure is building before a possible breakout.
There are two common types. A falling wedge slopes downward and is often seen as a bullish signal when price breaks above resistance. A rising wedge slopes upward and is often seen as a bearish signal when price breaks below support.
Example:
If a stock keeps making higher highs and higher lows, but the distance between them becomes smaller, it may form a rising wedge. If the price then breaks below the lower trendline, traders may see this as a sign that upward momentum is weakening and a move lower could follow.
Traders usually wait for confirmation, such as a clear breakout, stronger volume, or support from indicators like RSI or MACD. A wedge does not guarantee direction, so risk management is essential.
Wedge Chart Pattern
A wedge chart pattern is a technical analysis pattern that forms when price moves inside two narrowing trend lines. These lines connect recent highs and lows, creating a shape that looks like a wedge. Traders use it to spot a possible breakout, reversal, or continuation in price direction.
There are two main types. A rising wedge slopes upward and is usually seen as a bearish signal, meaning the price may break lower. A falling wedge slopes downward and is usually seen as a bullish signal, meaning the price may break higher.
The main thing to know is that the price is not moving much. When the price is stuck in an area people who buy and sell things wait for the price to go up or down before they do anything with the price momentum. The price momentum is what people are watching. They want to see what happens to the price momentum next.
Example:
A stock rises from $40 to $50, but each new high becomes weaker while the price range narrows. This forms a rising wedge. If the price breaks below the lower trend line, traders may see it as a signal that buying momentum is fading and a decline could follow.
Wedge patterns are useful, but traders often confirm them with volume, momentum indicators, or stop-loss levels.
