Backtesting

Saved sessions

What's persisted when you save a backtest, what isn't, and how sessions follow you across devices.

Saved sessions let you walk away from a backtest and come back later — same security, same position in time, same trade history — without re-running the whole replay. Sessions are scoped to your account and follow you across devices.

Saving is manual

Sessions are not auto-saved. You decide when a backtest is interesting enough to keep. Hit Save in the session panel; the engine snapshots the current state and pushes it to the cloud. From then on, "Save" updates the same session; rename it from the same panel.

On a fresh load (no edits since the last save), Save is a no-op — there's nothing new to snapshot.

What gets saved

Each saved session captures:

  • Security & data provider — ticker, asset class, source.
  • Date range — start, end, and the exact moment the replay was paused at.
  • Interval & last speed — so reopening drops you back at the same chart granularity and pace.
  • Account state — starting balance, current balance, equity.
  • Trades — every fill, closed trade, and pending order from the simulation.
  • Open positions — what was still in-market at save time.

What doesn't get saved

Chart layout and drawings are not part of a saved session. Trendlines, fibs, and on-chart annotations live in the chart's local memory only; reopening a saved session does not restore them.

Indicators behave differently. Custom indicators you've created and saved live in your account and are available on every device when you sign in. But which indicators are currently on the chart for a given session is part of the chart layout, not the session — so you may need to add them back when reopening a saved backtest.

Sessions list

Open the sessions panel to see your saved backtests. Each row shows the security, date range, trade count, and net P&L. From there you can:

  • Open — load the session into the engine and resume from the saved tick.
  • Rename — give it a meaningful name once a strategy is taking shape.
  • Duplicate — clone a session to branch into a "what if I'd done X here" variant without losing the original.
  • Delete — permanent. The session and its simulation history are removed from your account.

Cross-device sync

Sessions are tied to your StrategyTune account, not to a browser. Sign in on a different device and your saved sessions are there. There's no per-device cache that needs to be cleared, and no "export and re-import" step.

While you're signed out, you can still run replays and trade — but Save is disabled. Sign in to start saving.
