# Cycle indicators (Hilbert transform)

> Hilbert-transform dominant cycle period and phase, in-phase and quadrature components, sine and lead-sine waves, and the trend-versus-cycle mode.

Toolset `ta_cycle`: 1 tool.

| Tool | What it does | Notes |
| - | - | - |
| `ta_cycle` | A Hilbert-transform cycle indicator of the closes (or source, or one series): its output(s) aligned to the dates with the warm-up (63 bars for most) reported, the last values and a line chart. | |

Inputs, limits and outputs are described in [Fincept Technicals](/guides/fincept-technicals). Full schemas: `fincept_describe_tool`.
