Learn hubBlogLock in the words used on every screen that follows: order book, depth, delta, OI, funding, liquidation and the rest.
Words that come up on every screen. Order book, bids, asks and trades were on the previous screen — here they sit next to the rest. Read it once; you can come back any time.
| Order book | The list of limit orders. Bids (buy) sit below the price, asks (sell) above. |
| Bid / ask | A buy / sell order. DYOR counts them in dollars. |
| Limit / market | A limit order sits in the order book and waits for its price. A market order fills immediately against the order book. |
| Taker / maker | A taker fills with a market order, a maker places a limit order. “Buys” and “sells” in trade indicators are takers. |
| Depth | Distance from the current price in percent. A 3% depth is all asks from the price up to +3% and all bids from the price down to −3%. DYOR counts seven depths: 1.5 · 3 · 5 · 8 · 15 · 30 · 60%; each one includes the ones before it. |
| Bar | One candle on the chart. On the 15m timeframe a bar is 15 minutes. Indicators compute a value for each bar. |
| Delta | The difference between two values. Trade delta is buys minus sells; order book delta is bids minus asks. |
| Spot / futures | Spot is buying the coin itself. A future is a contract on the coin's price, traded with leverage. Most indicators have a SPOT / FUTURES switch. |
| Long / short | A long is a position betting on a rise (you bought). A short bets on a fall (you sold borrowed coins to buy them back cheaper). |
| Leverage / margin | Leverage is a position bigger than your own money; the exchange covers the difference. Margin is your own money behind that position. |
| OI | Open interest: the total of all open futures positions right now. |
| Funding | A periodic payment between longs and shorts on a perpetual future, usually every 8 hours. The sign of the rate shows who pays. |
| Liquidation | The exchange force-closes a position when the margin no longer covers the loss. |
| Stablecoin | A coin pegged to the dollar: USDT, USDC. |
| COIN / TOTAL | COIN is data for the coin on the chart. TOTAL is the sum across all coins on the market. It gets its own screen later. |
Order book: orders that wait. Trades: what got filled. Depth: distance from the price in percent. Delta: the difference between two sides. You can come back to this table from any screen.
“Bid at 3% depth” is…
Correct answer: The sum of buy orders from the price down to 3% below it
