Market Quality
Market microstructure terms for depth, impact, liquidity, order books, order queues, imbalances, stabilization, and transaction costs.
Trading terms for order types, execution, quotes, price increments, positions, market activity, and execution quality.
Trading and orders covers the market-structure terms that explain how instructions become trades: order types, quotes, spreads, price increments, market data, execution quality, trade size, positions, sessions, halts, and settlement workflow.
Use this section when the finance question depends on a trade ticket, order instruction, quote timestamp, bid-ask spread, venue route, execution report, market-data field, settlement date, or position record. This content is educational and is not trading, legal, tax, or investment advice.
| Area | Use it when the question is about | Evidence to check |
|---|---|---|
| Order Types and Execution | Market orders, limit orders, stop orders, duration instructions, fills, and execution mechanics | Order ticket, instruction, route, timestamp, fill price, partial-fill status, and cancel/replace log |
| Quotes, Prices, and Market Data | Bid, ask, spread, tick size, real-time quotes, tickers, screening tools, and price states | Data vendor, ticker, exchange, quote timestamp, delay status, market session, and price-increment rule |
| Market Quality and Microstructure | Liquidity, depth, transaction costs, order books, order queues, impact, and price discovery | Depth, spread, volume, queue position, market impact, and execution-cost estimate |
| Trade Size, Volume, and Market Activity | Block trades, lots, odd lots, round lots, volume, open interest, and trading activity | Trade size, lot convention, print record, volume source, open-interest date, and market segment |
| Trading Positions, Margin, and Short Selling | Open positions, short interest, locates, margin requirements, overnight positions, and position exposure | Position record, borrow locate, margin rule, account equity, short-interest date, and risk limit |
| Trading Sessions and Halts | Pre-market, after-hours, trading hours, halts, limits, and suspensions | Session calendar, halt notice, limit rule, exchange bulletin, and resumption time |
| Trade Reporting, Settlement, and Processing | Trade dates, regular-way settlement, when-issued trading, sell-outs, confirmations, and processing | Trade date, settlement date, confirmation, clearing route, fail status, and processing exception |
| Price Action, Sentiment, and Volatility | Gaps, rallies, overbought language, whipsaws, sentiment terms, and volatility references | Price series, session range, volume, volatility measure, indicator setting, and time window |
Start with Order Types and Execution when the term controls what a broker or venue should do. Use Quotes, Prices, and Market Data when the issue is a displayed price, data feed, ticker, screener, or price state. Use Trade Reporting, Settlement, and Processing when the question turns on trade date, settlement date, confirmation, clearing, or fails.
Use Market Quality and Microstructure when a term changes liquidity, depth, impact, or transaction cost. Use Trading Positions, Margin, and Short Selling when the evidence belongs to an account, borrow, margin, or position record.
