Heatmap — cells
Coin rows, grid, cell numbers and width relative to candles.
Show heatmap cells (on by default) draws the coin rows. Turn it off if you only want the Σ strips — at least one of cells or Σ bars / % must stay on. Cell grid (on) draws hairlines over the cells. Show cell numbers (K) (off) prints the Stoch value in the cell; Hide 0 / 100 numbers (on) blanks those extremes while the colour stays. Cell width = candle width (off) makes each cell match the candle body when the matrix shares the chart time scale; off keeps flush full-bar spacing.
History always loads 1000 bars from the feed (Bybit’s maximum). Cells follow
the chart time scale (sync); older “legacy” fixed-width layouts are coerced to
sync when a tab is loaded. The legacy cell-width value (16 px) is kept in
storage for that old path but is not what the live product uses after normalize.
Candles are not toggled from matrix settings — on a Surface they belong on the
chart above.
