Read the curves and legend

The toolbar above the risk graph sums up the curve in focus, and the legend on the graph lists every curve with its P&L at one price. Read them together to see the trade’s range of outcomes.

The toolbar sums up the curve in focus.

  1. 1 Max P and Max L
  2. 2 PoP at expiration
  3. 3 Greeks of the focus curve
  4. 4 Risk graph settings
  • Max P / Max L: the best and worst case at expiration, or “Unlimited”. One expiration gives exact figures. With several, “Unlimited” still shows when a side has no bound, but a bounded figure is the extreme inside the chart’s price range and the tooltip says so. See Max profit and max loss.
  • Credit / Debit: the opening price per unit of the structure; unfilled legs count at their mid.
  • PoP: probability of profit at expiration. The tooltip names the distribution and one standard move. See Probability of profit.
  • Δ Γ Θ V: the focus curve’s Greeks in position units (delta in shares, theta in dollars a day).
  • ≈ before a figure means a leg is valued on an estimate. The “N legs estimated” chip lists them. See Estimated marks.

The legend. It lists each curve with its P&L at the projection strip’s price (live spot unless you changed it). Click a row to hide or show that curve; click the header to collapse the legend to one row of values.
