- Script: --seed-chart flag writes OHLCV candles into dashboard_history.db
- Dashboard: auto-seeds from ohlcv/*.json on first run if DB is empty
- Dashboard: /history/symbols endpoint for pre-populating chart dropdown
- Frontend: loads available symbols on page load for pre-session chart display
- Fix HISTORY_DB default path after shared_data -> shared/data merge
- 1W shows ~5 daily candles, 1M shows ~20 daily candles with real prices

Add dynamic LLM provider/model selection to AI Analyst
- ai_analyst: add Groq support, _active_provider/_active_model globals,
refactored call_llm routing (Ollama → Groq → HF auto fallback),
handle Kafka 'set_llm' control message to switch provider at runtime
- dashboard: /ai/select now publishes set_llm to Kafka control topic so
the AI Analyst service picks up provider changes immediately
- dashboard + index.html: sync LLM selector UI (provider/model dropdowns,
badge, SSE llm_config event) to latest working version

Fix AI Analyst: align model default, actionable provider-not-enabled error
- dashboard.py: change HF_MODEL default from Qwen2.5-3B to Qwen2.5-7B-Instruct-1M
(matches docker-compose ai_analyst service)
- Detect 400 model_not_supported / provider errors and return a clear message
with link to huggingface.co/settings/inference-providers
- /ai/debug: add "fix" field with provider setup instructions when 400 occurs
- docker-compose: add HF_TOKEN + HF_MODEL env vars to dashboard service
- index.html: error insights shown in red; status header turns red on error

Fix Generate Now: move LLM call into dashboard.py directly
- Scheduler: change elif condition to start_t <= now < end_t so the
session is never auto-started when current time is past end time
(previously: end at 17:00, then next tick 17:00>=10:00 restarts it)
- nginx: replace localhost with 127.0.0.1 to avoid IPv6 connection
refused errors on HuggingFace (localhost resolves to ::1 there)
- AI panel: indigo top border + shadow to make it visually distinct;
button enlarged and labelled with ✨ for better discoverability

AI Analyst: add Generate Now button for on-demand insights
- Button in AI Analyst panel header calls POST /session/ai_insight
- Dashboard publishes {"action": "generate_insight"} to control topic
- ai_analyst listens and runs LLM call in a background thread
- Button shows "Generating…" / disabled while waiting, re-enables on result
- Fix: control topic key was "command", now correctly uses "action"

Add AI Analyst service: Ollama (local) + HuggingFace (HF Spaces)
New ai_analyst/ai_analyst.py service consumes trades/snapshots from
Kafka, builds a market-context prompt every 30 min, calls Ollama
(llama3.1:8b) locally or HuggingFace Inference API (Mistral-7B) as
fallback, and publishes insights to the ai_insights Kafka topic.
Dashboard consumes ai_insights and broadcasts via SSE. New full-width
AI Analyst panel displays timestamped insights with animated cards.
- ai_analyst/ai_analyst.py: new service (Ollama-first, HF fallback)
- ai_analyst/Dockerfile: minimal Python image for local compose
- shared/config.py: add AI_INSIGHTS_TOPIC
- dashboard/dashboard.py: consume ai_insights, SSE broadcast
- dashboard/templates/index.html: AI Analyst panel + JS handlers
- Dockerfile: copy ai_analyst.py into HF single-container image
- entrypoint.sh: create ai_insights topic, start ai_analyst.py
- docker-compose.yml: ai_analyst service with OLLAMA_HOST + HF_TOKEN

Replace the individual orange dots with a continuous orange polyline +
dots overlay. Remove the filled candlestick bodies (keep wicks) so the
horizontal flat lines no longer clutter each price point.

Frontend (disconnected root cause):
- All fetch('/endpoint') calls were hitting nginx '/' (dashboard) instead
of '/frontend/endpoint'. Added BASE detection at page load:
const BASE = window.location.pathname === '/' ? '' : pathname.replace(/\/$/, '');
Applied to /securities, /order, /book, /trades
FIX UI (session disrupted by reloader):
- debug=True caused Flask reloader to spawn a child process and restart
the app, breaking the QuickFIX session on startup
- Changed to debug=False, use_reloader=False
Entrypoint timing:
- FIX OEG sleep increased from 3s → 6s (allow full socket bind)
- FIX UI sleep increased from 2s → 3s (allow QuickFIX initiator to start)
Dashboard:
- Local clock added to header bar (updates every second, browser timezone)

Add Frontend button to dashboard; wire frontend into single-container
Dashboard:
- FRONTEND_URL env var injected into template; button only shown when set
- docker-compose: FRONTEND_URL=http://localhost:5000 added to dashboard service
- Button opens frontend in new tab (indigo pill style, matching FIX UI)
Single-container (HuggingFace):
- nginx: /frontend/ route added → localhost:5003
- entrypoint.sh: starts frontend on port 5003 with correct template folder
- Dockerfile: copies frontend.py + templates to /app/frontend_templates/
- frontend.py: TEMPLATE_FOLDER env var support added
- Dockerfile: also copies market_schedule.txt to /app/data/

Price chart:
- Volume bars narrowed to 25% slot width, capped at 5px
- Close-price overlay replaced with orange dots per candle (not a line)
- Legend updated to dot symbol instead of line
Multi-symbol chart:
- Volume data now passed from loadAllHistory (live + candle modes)
- drawMultiChart splits into 70% price / 30% volume when volumes present
- Aggregated volume bars (sum across symbols per 60s bucket) shown below
- Volume Y-axis labels on right side (0, 50%, max)
FIX UI:
- Added "← Dashboard" back button in header (links to /)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Volume bars width reduced to 35% of slot (was 65%) for cleaner chart
- Volume Y-axis labels added on right side (0, 50%, max) with k-suffix
- pad.right widened to 46px to accommodate volume labels
- Trading Statistics thead row: background #f0f0f0 (matches Orders/Trades)
- Auto mode: End of Day button stays enabled when session is active
- Default mode changed to Automatic (backend + frontend)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Add Start/End Day toggle, Manual/Automatic mode with schedule-based auto-trading
- Merge Start of Day / End of Day into single toggle button (green→Start, orange→End)
- Add Manual/Automatic toggle button; Automatic mode disables manual day control
- Add shared_data/market_schedule.txt (Start 10:00, End 17:00)
- Backend: schedule_runner thread auto-starts at 10:00, auto-ends at 17:00
- Backend: POST /session/mode endpoint; broadcasts mode via SSE
- Fix scheduler logic: end check takes priority, nothing fires before 10:00

Price Chart: show all securities as normalised % chart when no symbol selected
- Default selection is "All Symbols" (empty value) instead of auto-picking first symbol
- drawMultiChart(): plots each security as a % change line from its first data point,
so differently-priced securities (e.g. EXAE ~42 vs AAAK ~4) are comparable on one chart
- Right-side vertical legend with colour-coded symbol names
- Zero-line dashed when chart spans positive and negative % territory
- loadAllHistory(): live mode groups state.trades by symbol; historical mode fetches
all symbols in parallel via Promise.all and draws the multi-line chart
- loadHistory() routes to loadAllHistory() when no symbol is selected

Move Price Chart into grid beside Trading Statistics; traditional chart style
- Remove standalone Trade Chart panel from the grid
- Rename Price History panel to Price Chart (full-width, below grid)
- Add "Live" as default period option: shows last 100 trades as a line chart
that auto-refreshes on every SSE trade event
- Historical periods (1H/8H/1D/1W/1M) now also use a consistent line chart
style (close price line + gradient fill + volume bars) instead of candlesticks
- Unified drawChart() function renders both live trades and OHLCV candles with
the same visual: green line, gradient fill, blue volume bars, time axis
- Remove renderPriceChart() and dead #chart-symbol dropdown references

- md_feeder: add _suspended flag; handle suspend/resume control messages
to pause/unpause order generation without ending the session
- dashboard: add suspended field to session_state; add POST /session/suspend
and POST /session/resume endpoints that publish to control topic
- dashboard template: Suspend button (blue-grey) between Start and End of Day;
toggles to Resume (green) when paused; session badge shows PAUSED (amber)
with pulsing dot when suspended; button disabled when session is idle
