Typical tick fields
Timestamp, price, volume and side are common. Vendors use different names — normalize in your integration layer.
Ticks vs candles
Candles aggregate ticks over an interval. Backtests often use candles; execution and market making need ticks or Level 2 depth.
Getting ticks via API
TIQEX pushes live updates over WebSocket and serves snapshots/history over REST. Pick granularity by use case and confirm entitlements.
With klines
Execution cares about ticks/streams; research/backtests usually use OHLCV. One auth model covers both channels.
