Time controls
Speed, intervals, jumps, and the keyboard shortcuts that drive them.
Time control is the heart of StrategyTune. You can replay at anywhere from real-time pace to fifty thousand times faster, jump anywhere in history, and switch chart intervals on the fly. None of these reload the engine — the replay just adjusts and keeps going.
Speed
Speed is a discrete ladder of fifteen steps:
1× · 2× · 5× · 10× · 20× · 50× · 100× · 200× · 500× · 1,000× · 2,000× · 5,000× · 10,000× · 20,000× · 50,000×
New replays start at 200× by default. The ladder is geometric: each step is roughly 2–3× the previous, which keeps the controls usable across the full range.
- Speed selector: dropdown in the controls bar, or use the +/- buttons.
- Hotkeys:
↑/↓step the ladder up / down. - Speed can be changed any time the engine is running or ready to start. The change takes effect on the next frame — no reload, no jump.
Higher speeds are still tick-accurate. Speed only changes the wall-clock time between frames; it does not skip ticks or
interpolate. 50,000× means a long backtest finishes fast — not that
ticks were dropped.
Chart interval
The chart can be drawn at any of these intervals:
1m · 3m · 5m · 15m · 30m · 1h · 4h · 1D
Default is 15m. Changing intervals doesn't change the replay clock — only how
candles are drawn. Your trades, P&L, and indicators stay correct across intervals because
they all bind to the underlying tick stream, not to a particular candle size.
- Hotkeys:
Shift+↑/Shift+↓step the interval up / down.
Jumping in time
The progress bar at the bottom of the chart is interactive. Drag the thumb to scrub anywhere in the date range; the engine pauses, loads the momentum bar at that timestamp, and shows you the chart as it was right then. When you release, replay resumes from there if it was running.
This is how you do "what would have happened if I'd entered here" — drop the thumb on a time, place the trade, hit Play.
Pause and resume
- Space toggles play / pause. From a fresh load, Space presses Play. Mid-replay, it pauses; press it again to resume.
- Pause is instant — no in-flight tick is dropped. The next press of Space picks up on the very next momentum bar.
Hotkey reference
| Key | Action |
|---|---|
Space | Play / pause / resume |
↑ | Speed up one step |
↓ | Speed down one step |
Shift+↑ | Larger interval (e.g. 5m → 15m) |
Shift+↓ | Smaller interval (e.g. 15m → 5m) |
Shift+F | Toggle fullscreen |
Shortcuts are silent whenever you're typing, so they never accidentally pause the replay or change speed while you're entering text somewhere else.
