Working alongside **4CastMachine AI**, the Assistant applies your chart changes in seconds and gives you an Undo button on every card. Example: Tell the Assistant: "Open `XAUUSD` on `15m` to check the `4018.90` pivot, the Buy zone from `4018.90` to `4055.92`, and targets `R1 4067.88` to `R5 4125.55`.

You can open [spot gold (XAUUSD)]() or `BTCUSD` across all nine timeframes from `1m` to `M`. - **Switch symbol and timeframe together:** Say "Open `XAUUSD` on `15m`". You immediately see the live pivot at `4018.90`, the **Buy zone** from `4018.90` to `4055.92`, and profit targets from `R1 4067.88` to `R5 4125.55`. - **Pin favorite timeframes to the top toolbar:** Say "Pin `5m`, `15m`, `1h`, `4h` and `D` to the top chart toolbar". - **Change the chart type:** Ask to switch between Candles, **Heikin Ashi**, Hollow Candles, Line, Area, or Candles + Daily shadow overlay. - **Zoom, reset view and jump to dates:** Say "Zoom out slightly" or "Reset the chart view".

Multi-chart workspaces let you monitor correlated assets or check [top-down multi-timeframe alignment]() across up to 16 panels without opening layout menus. - **Split the screen across 1 to 16 charts:** Say "Open a 6-chart layout with `EURUSD`, `GBPUSD`, `USDJPY`, `XAUUSD`, `BTCUSD` and `ETHUSD`". Layouts of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14 and 16 charts are supported. - **Sync panels across your layout:** Say "Turn on timeframe and `crosshair` synchronization across all charts, and keep symbol sync off". - **Save, switch, duplicate and share workspaces:** Say "Save this workspace as Crypto Scalping and favorite it". You can also say "Switch to my Forex Swing workspace" or "Give me a share link". ## What chart settings and 4CastMachine AI layers can you toggle? The **4CastMachine AI** forecast layer is always on by default. Every supported symbol opens with its active [Buy zone, Sell zone and Reverse zone]() already visible on the chart. - **Forecast and higher-timeframe lines:** Say "Show higher-timeframe support, resistance and trendlines on the chart". You can also say "Hide the **4CastMachine AI** forecast layer temporarily". - **Price scale and timezone:** Ask to switch the vertical price scale to logarithmic, percentage or inverted mode. You can also set the chart timezone to `Europe/London` before the [London and New York session overlap](). - **Session breaks, grid lines and theme:** Say "Turn on **Session breaks** on the chart". Or say "Hide vertical and horizontal grid lines" or "Switch the chart to dark mode". - **Journal trades and side panels:** Say "Show my open and closed journal trades on the chart". Or say "Open the watchlist panel" or "Hide the left drawing toolbar". ## How do you run Bar Replay, Blind chart and snapshots? Practice price action on historical candles or share a clean chart picture with a single voice or text command. - **Start and control Bar Replay:** Say "Start **Bar Replay** from `2026-10-15 08:00`". Then say "Step forward 10 candles", "Pause replay", or "Exit replay mode". - **Practice in Blind chart mode:** Say "Start **Blind chart** practice" to open a randomized symbol and date range with ticker names hidden. - **Capture and share chart snapshots:** Say "Download a PNG snapshot of this chart" or "Copy the chart snapshot link".
