Full changelog

Two visible bugs fixed after using the platform end-to-end through a real close + symbol-switch flow.

What's fixed

Day P&L now updates on close

/api/day_pnl read from journal_dir/<date>/trades.json — but no code path in v0.1.x writes to that file. Realized P&L is recorded to the SQLite journal_entries table (via the per-close auto-recompute we shipped earlier today). The endpoint now queries the right place, so Day P&L updates immediately after a close instead of staying at $0.

The response also now exposes realized_pnl and unrealized_pnl as separate fields if you want to surface the breakdown in the UI later.

Chart no longer blank after switching symbols

ChartManager.setSymbol() called timeScale().fitContent() to fit the new symbol's bars — but that only fits the time axis. The price axis stayed at the previous symbol's range. Switching from SPY (~$750) to AMZN (~$268) left the chart's price scale at 744-755 and every AMZN bar rendered off-screen. Added priceScale('right').applyOptions({ autoScale: true }) after fitContent() so the price axis re-fits.

How to upgrade

git pull
# restart the launcher, refresh the browser tab

Verified

Closed a SPY 751P position → Day P&L immediately shows the realized P&L (no manual journal-file step needed)
AAPL → AMZN → SPY symbol switches all render bars at the correct price range
All v0.1.1 — v0.1.4 fixes intact (CSRF, gevent, position auto-import, 0 DTE)
