A malicious website or script that persuades you to connect your wallet and sign a request which lets the attacker move your funds.
Example: A fake sale page asks you to sign a request that grants an attacker spending power. Connecting a wallet and approving a signature are distinct steps; inspect each request.
Keep in mind: Connection alone does not necessarily authorise spending, but a separate signature or approval can create dangerous permissions.
Buying and selling the same asset at nearly the same time without any real change in who owns it, usually to make trading look busier than it is.
Example: A seller repeatedly trades an item between accounts it controls to make demand look strong. Reported activity can rise without independent buyers or genuine ownership changes.
Keep in mind: The two retained source definitions describe the same broad concept. Suspicious activity needs evidence; high volume alone is not proof of manipulation.
Buying and selling the same asset, at the same time, without any real change in who owns it, to create a false picture of trading volume and demand.
A wallet that tracks addresses using public information without holding their signing keys. It can display activity and, in some implementations, prepare transactions or broadcast transactions signed elsewhere. It cannot independently authorise spending from those addresses.
Example: A shared budget dashboard displays balances but cannot authorise payments. A watch only wallet similarly observes public information without holding the signing keys.
A difference between a price before a weekend closure and a later price when quoting or trading resumes.
Example: A shop’s Friday price may differ from the price displayed when it next opens.
Keep in mind: A stop instruction does not guarantee that execution will occur at a requested price across a gap.
The sum of each executed price multiplied by its filled quantity, divided by total filled quantity in compatible units.
Example: Invented fills of 100 units at 1.10 and 200 at 1.12 give (110 + 224)/300, about 1.11333 per unit.
Keep in mind: Use actual compatible fills and quantity weights; a simple unweighted average gives a different figure.
The part of a conventional candlestick showing an extreme beyond the open-to-close body, also called a shadow.
Example: With open 10, close 12, high 13 and low 9, the wicks cover 12–13 and 9–10.
Keep in mind: A wick does not identify who traded or prove the next price direction.
The fraction of completed cases with positive results under the stated result and cost convention, using the defined denominator.
Example: In an invented ledger with two wins, one loss and one zero, wins are 2 of 4 completed cases: 50%.
Keep in mind: Zeros and unresolved cases need distinct treatment; sample win rate is not an established future win probability.
A setting that lets your account send crypto only to addresses you have saved in advance, often with a waiting period before a new address can be used.
Example: A payment account permits transfers only to saved destinations. A waiting period may help review a new destination, but the control does not guarantee the destination or account is safe.
A charge for a withdrawal under the provider’s and payment route’s terms.
Example: Withdrawing an invented 50-unit amount may carry a separately stated 2-unit fee.
Keep in mind: A withdrawal reduces cash balance but is not itself a trading loss; unexplained advance payment demands need scrutiny.
