**Use Cases** [🧩 SDK](https://api.docs.coins.ph/reference/general#sdk)
- **Instrument Discovery** — Enumerate all active trading pairs to know which symbols are available before placing order.
**Best Practices**
- Cache the trading pairs list and refresh periodically (e.g., every 5–10 minutes).
- Use the `symbol` field when making requests to other market data endpoints.
- Validate trading pairs before attempting to place orders.
- Handle empty arrays gracefully in case no trading pairs are available.

**Use Cases** [🧩 SDK](https://api.docs.coins.ph/reference/general#sdk)
- **Pre-Trade Liquidity Check** — Inspect available depth before placing a large order to estimate fill size and average execution price.
- **Spread Assessment** — Compare `bids[0][0]` and `asks[0][0]` to measure market tightness before entering a position.
- **Market-Making** — Poll top-of-book continuously to set competitive bid/ask prices on both sides.
- **Slippage Estimation** — Walk through depth levels to predict average fill price for a given order size before submitting.
**Best Practices**
- Use smaller limits (5, 10, 20) for UI display; use larger limits (100, 200) for trading algorithms.
- Use `lastUpdateId` to track order book changes.
- Consider using WebSocket streams for real-time updates.
- Monitor your weight consumption and implement exponential backoff for retries.

**Use Cases** [🧩 SDK](https://api.docs.coins.ph/reference/general#sdk)
- **Technical Analysis** — Fetch recent klines to compute indicators (MA, RSI, Bollinger Bands) before an algorithm decides to place an order.
- **Backtesting** — Download historical klines to simulate strategy performance against real past price action before going live.
- **Volume Analysis** — Aggregate taker buy volume across intervals to gauge directional pressure and confirm a trend.
**Best Practices**
- Cache historical kline data locally to reduce API calls.
- Use `startTime` and `endTime` to paginate through historical data.
- Choose appropriate intervals: short (1m, 5m) for intraday; medium (1h, 4h) for swing trading; long (1d, 1w) for position trading.
- Don''t request more data than needed; use appropriate limit values.
- All price and volume fields are returned as strings to maintain precision.

summary: 24hr Ticker Price Change Statistics
description: 'Retrieves 24-hour rolling window price change statistics for one or multiple trading symbols. Returns comprehensive market data including price changes, volumes, and trading counts.
**Careful** when accessing this endpoint with no `symbol` parameter — it returns data for all symbols at a higher weight cost.
Use `symbol` for a single pair, `symbols` for multiple specific pairs (JSON array format, e.g., `["BTCUSDT","BNBUSDT"]`). `symbol` and `symbols` cannot be used in combination.
**Price change calculations:**
- `priceChange` = `lastPrice` − `openPrice`
- `priceChangePercent` = `((lastPrice − openPrice) / openPrice) × 100`
- `weightedAvgPrice` = `quoteVolume / volume`

| symbols (101+ symbols) | 40 |
| symbol omitted (all symbols) | 40 |
**Use Cases** [🧩 SDK](https://api.docs.coins.ph/reference/general#sdk)
- **Market Overview** — Load 24h stats for all symbols to render a market screener with price change, volume, and high/low per pair.
- **Price Change Alerts** — Monitor `priceChangePercent` across symbols to detect when a threshold is breached and trigger a notification.
- **Volume Ranking** — Sort symbols by `quoteVolume` to identify the most actively traded pairs and allocate attention or liquidity accordingly.
**Best Practices**
- Use `symbol` for a single pair; use `symbols` for multiple; omit both only when you truly need all symbols.
- Cache ticker data when real-time updates aren''t critical.
- Use WebSocket streams for continuous real-time data instead of polling.
- Requesting all symbols uses 40× more weight than a single symbol.

**Use Cases** [🧩 SDK](https://api.docs.coins.ph/reference/general#sdk)
- **Limit Order Pricing** — Read the best bid and ask before submitting a limit order to set a competitive price without crossing the spread unnecessarily.
- **Spread Monitoring** — Subtract `bidPrice` from `askPrice` to assess current market liquidity before entering a position.
- **Lightweight Level-1 Check** — Use this instead of the full order book when only the best price is needed, to reduce latency.
**Best Practices**
- Use this endpoint for top-of-book data; use the full Order Book endpoint when you need market depth.
- All prices and quantities are returned as **strings** to preserve precision.
- Calculate spread as `askPrice − bidPrice`; tight spreads indicate liquid markets.
- For continuous updates, consider WebSocket streams (`<symbol>@bookTicker`).
