| Operating system | Windows 10 (build 1803+) or Windows 11, 64‑bit. Windows only — there is no macOS or Linux build. On Windows 10 the system draws a yellow border around captured screens while recording (a Windows indicator Recap can’t disable there; it is not in the footage) — Windows 11 records without it. |
| GPU / encoder | A GPU with a hardware H.264 encoder and an attached display. Recap requires a hardware H.264 encoder to record; if none is available, it shows a “No encoder” warning and won’t start. |
| Disk | Substantial free space. Recap records your full session to disk (idle time included) — on the order of tens of GB per day, more with multiple monitors. A retention policy keeps this bounded (default: keep 7 days or 200 GiB, whichever hits first). A disk‑full guard self‑stops recording when free space drops below ~200 MB. |
| Account | A Recap account (sign in with Google or an emailed sign‑in code). The app is gated behind sign‑in. |
| Runtime redistributables | None. There’s nothing extra to install — just run Recap. |
| A supported trading platform | A platform connector feeds your trades to Recap. Stable connectors are available for Sierra Chart, NinjaTrader, and MotiveWave; Quantower and ATAS X connectors are in beta. A direct Tradovate account connection is also in beta and needs no platform add‑on — see Connect your platform. |
