3. Technical Trading (Charting)

Relative value has its own chart: the ratio between your two legs. Instead of reading BTC and ETH separately, you read BTC/ETH as one line, and the whole technical toolkit (support/resistance, trend, mean-reversion) applies to it.

Orchard charts the spread with the analytics that matter for pairs: a rolling z-score with ±2σ bands (how stretched the spread is versus its own recent history), correlation overlays (is the relationship holding?), and the hedge ratio (how to size the legs so the chart reflects a clean spread, not a lopsided one). A mean-reversion trader fades the spread when the z-score tags ±2σ and targets the mean; a momentum trader plays breakouts in relative strength when one side decisively pulls away. Pick your window 1H / 4H / 1D to match your horizon, choose the order type that fits the setup (Market, Limit/Trigger, TWAP for size, or Ladder to scale in), and set TP/SL on the ratio itself.
