• Settings — stake, SL, TP now entered as % of capital; engine computes dollar amounts at session open from live balance
• EO safeguards — separate EO max runs (default 30) and per-session EO loss cap (% of capital)
• EO side cooldown — after a 4-loss chain, the losing side (ODD/EVEN) is blocked for 5 min; bot trades the other side if a signal exists
• Session end — asset name added to Telegram notification
• Telegram settings — now sync live to running engine on Save (was localStorage-only)

• Settings hydration — opening any browser anywhere auto-populates all settings (including Telegram) from the running server instance
• Admin live feed — balance events, Feed clients KPI, connected banner
• Admin users table — real account name (when available from Deriv profile)
• Docs locked behind Deriv auth gate

• Server-side bot — closes browser, bot keeps running on VPS
• Multi-user — each Deriv account gets its own isolated bot instance
• Admin dashboard — fleet overview, live feed, per-user drilldown

• Deriv OAuth login — connect with your Deriv account instead of pasting an API Key; supports Live + Demo switching

• DYNAMIC mode sets TP/SL as editable defaults — fields remain open so you can fine-tune without losing auto-calculated values; stake fields stay read-only

• Fix: DYNAMIC no longer shrinks Stop Loss mid-session — SL/TP lock at session start, preventing balance fluctuations from collapsing the stop gate during a martingale run

• Fix: DYNAMIC settings now applied immediately on connect — stake/TP/SL recalculate as soon as balance loads, not just after trades
• Help menu — What's New, Documentation, Check for Updates, Report an Issue, About
• Auto-update: app checks for new releases on launch and prompts to restart when ready

• Removed Legacy (API Token) connection mode — API Key (PAT) is now the only supported auth method
• Connection panel simplified: API Key + App ID always visible; no mode toggle
• Fix: account token restore no longer ignores pat_ tokens when loading saved Live/Demo keys

• Fix: pre-trade SL gate — stake that would breach session stop loss is blocked before the proposal is sent (was checked only after settlement)
• Fix: 3 consecutive trade timeouts now trigger an automatic WS reconnect instead of re-entering on a broken subscription
• Fix: 4-consecutive-loss circuit breaker — pauses new entries for 60s after 4 straight losses, then auto-resumes; resets on any win or new session

• Auto-resume: bot restarts automatically after an unexpected disconnect — no manual Start required
• Reconnect now uses the token active at drop time — Demo/Live account is preserved across reconnects
• Linked alt-account token is no longer cleared on auto-reconnect

• ODD/EVEN signal: both sides now evaluated independently — the stronger hot-digit percentage wins instead of ODD always taking priority

• Fixed: Legacy reconnect no longer picks up a PAT token from localStorage when the partner previously connected in API Key mode (and vice versa)

• Fixed: API Key mode now uses underlying_symbol in trade proposals — resolves "Properties not allowed: symbol" errors on custom App IDs

• Fixed: Demo/Live toggle now appears in API Key mode after connecting (was hidden because state.connected was not yet true when the toggle first rendered)

• API Key mode account switching: Live↔Demo now triggers the full OTP flow with the target account's PAT
• Fixed: Demo account misclassified as Live — Deriv REST returns "demo" not "virtual" for demo accounts
• Alt-account section in API Key mode now prompts for a PAT (pat_xxx) from developers.deriv.com

• Fixed: state.accounts.live always null — Deriv account_list omits tokens; primary token now captured before authorize response and saved to typed key
• Fixed: race condition on account switch — old WS close event could fire after connect() re-enabled auto-reconnect

• Fixed: Demo→Live switch now instant — was taking ~5 min because Deriv silently drops re-authorize on an existing connection; app now disconnects and reconnects cleanly

• Fixed: account switch looping on Demo — single dba_alt_token key was ambiguous after switching; replaced with typed dba_live_token / dba_demo_token keys

• Demo/Live segmented toggle added directly in Connection panel — visible and usable in both Legacy and API Key modes
• Active account highlighted (amber = Demo, green = Live); clicking unavailable account prompts for token inline

• Fixed: accordion content clipped on mobile — sidebar flex-shrink was compressing cards; all options now fully visible with scroll

• Mobile accordion padding, touch targets, and single-column form grid improvements

• Removed accordion pinning — one accordion open at a time; tapping a header closes the current and opens the new one

• Fixed: Excel export now includes row colors — replaced xlsx with xlsx-js-style (free fork that honours cell styles)

• Light/dark theme toggle — sun/moon button in topbar; preference saved across sessions

• Export activity log to Excel — color-coded rows (green = win, red = loss, amber = signal/system)

• Multi-mode trade side — select Even, Odd, Under 4/6/8 simultaneously as checkboxes; first qualifying signal across all active modes fires the trade

• Fixed: lookback window inconsistency — processTick and fetchTicksHistory now both default to 1000 ticks; 5000 max cap enforced

• WebSocket keepalive ping every 25s — prevents Deriv idle timeout mid-session
• Auto-reconnect on unexpected disconnect — reconnects within 3s, stops cleanly on manual disconnect
• Asset locked during active session — market dropdown reverts and warns if changed mid-run
• Fixed: scanner cursor invisible on hot digit — last-tick highlight restored with !important

• Fixed: API Key mode now correctly shows Demo/Live badge and alt-token section on connect
• Fixed: removed invalid underlying_symbol field from proposal payload (was causing trade errors in API Key mode)

• Alt-account token linking instructions now mode-aware — API Key users and Legacy users see different guidance

• Live/Demo account switching — link your alternate account token in the Connection panel to enable one-tap switching without reconnecting

• Account badge now shows switch target (e.g. "Demo → Live") and is clickable
• Tooltip on badge confirms action or explains why switching is unavailable
• Fixed: day-key month was 0-indexed (Jan showed as 0) — now correctly 1–12
• Fixed: proposal failure now resets inTrade lock (bot no longer freezes on Deriv error)
• Fixed: stale proposal can no longer execute a buy in the wrong session
• Fixed: account switch no longer creates duplicate tick/balance subscriptions
• Daily P&L, peak, and halt state now persist across page reloads
• Ghost proposal_open_contract subscriptions cancelled after each trade and on stop

• New contract modes: Under 4, Under 6, Under 8 — selectable from Trade side dropdown
• Under 4: enters when all four digits 0–3 exceed strength threshold; fires on any 0–3 tick
• Under 6: enters when digits 6–9 all drop below 10%; fires when scanner lands on 7, 8 or 9
• Under 8: enters when digits 7–9 are stable (no trend); fires on 2 consecutive 7/8/9 ticks
• Amber scanner highlight for UNDER trigger digits; trade badge shows contract mode
• Signal panel shows live qualifying status for each UNDER mode while waiting

• Trade settings persist across page reloads — all fields (stake, martingale, runs, SL/TP, break, market, scanner thresholds, daily risk) saved automatically
• "Reset trade settings to capital defaults" button recalculates from live balance and applies risk-calculator values in one click

• Daily P/L, peak, and halt state now persist across page reloads — daily risk controls survive a refresh
• Fixed: proposal failure no longer locks the bot permanently (inTrade was never reset on proposal error)
• Fixed: stale proposal from a previous session can no longer execute a buy in the wrong session
• Fixed: account switch no longer creates duplicate tick/balance subscriptions
• Ghost proposal_open_contract subscriptions cancelled on every trade settle, timeout, and bot stop
• Dirty trade state (currentTradeId, pendingProposal) cleared on WebSocket close and session open

• Configurable daily reset time — set any UTC hour (0–23) as your day boundary
• Live countdown to next reset — "Resets in Xh XXm XXs" updates every second
• UTC-aware day key — day boundary correctly handles hours before/after reset hour
• Reset hour persists across page refreshes via localStorage

• Daily stop loss — halts trading if total day losses exceed limit
• Daily take profit — locks in gains and stops for the day
• Profit protection — trailing stop on daily peak P&L (prevents giving back gains)
• Daily P/L shown in topbar (Day) and Daily risk controls panel
• Auto-reset daily stats at midnight via localStorage date check

• Fixed: digit 0 always showing 0% (JS trailing-zero stripping on float prices)
• Fixed: ODD/EVEN percentages now match DCircles (root cause was digit 0 bug)
• Fixed: EVEN trades now fire when parity conditions are met
• Fixed: entry now gates on HOT digit tick — bot waits for scanner to land on target
• Fixed: no more trades on non-qualifying digits
• Fixed: reconnect no longer causes uncontrolled trading (full state reset on close)
• Lookback default and max raised to 1000 to match DCircles sample size

• Fixed: trade stuck in "In progress..." when buy fails with Deriv error
• Fixed: watchdog timeout increased 5s → 15s to handle slow contract settlement
• Fixed: late contract results after watchdog fire are now ignored (no double-count)
• Scanner cursor flash extended to 900ms for smoother digit tracking
• Seeded aggressive defaults: Stake $3, Runs 30, TP $50, Break 30s, Parity 51%, Strength 10.5%, Min qualifying 2

• Risk calculator: enter balance → stake auto-calculated
• Stop Loss and Take Profit now derived from worst-case exposure
