What the diary watches

  • Grid — 1×1 up to 2×2. Cells are synchronized: pan or zoom one and the others follow the same dates; the crosshair tracks across all of them. 4 INDICES loads Rubin · HALO · AEI · AW40 side by side.
  • Type / Scale — OHLC, line or area; linear or log price axis.

  • Tap the box in a cell's header to browse every Closelooknet series — headline indices, sub-indices, sectors, layers of all six families — plus the constituents.
  • Or type any ticker (NVDA, 7203.T, ASML.AS …) and press Enter — it charts in the cell straight from our data lake.

Studies

  • Overlays / Oscillators rows toggle the standard set (SMA, Bollinger, RSI, MACD …) per cell.
  • Levels (stock cells) draws the structure engine's support lines — regression bands, pivot cluster, SMA-200, the active fib zone.

  • Delete key removes the selected drawing · Escape cancels a half-placed one · Clear wipes the symbol.

Wave counts

  • On stocks the scanner's machine count appears automatically in grey — it is fully editable: drag any point, double-tap a label to remove it, Delete to dismiss it for good, Adopt to bring the machine's proposal back.
  • The sequence picker switches 1-5 / A-B-C / A-E / W-X-Y-Z; 1 2 3 cycles the degree; Subdiv starts a one-degree-smaller child count inside a wave.
