One lot of BANKNIFTY, 25 units, priced at the settled close of Fri 18 Sep 2026. The small pair under each figure is the same position after one ordinary daily move of about 574 points — down first, then up. Halfway to expiry, on Wed 23 Sep 2026, the same position reads differently again; the builder shows it for the legs you choose.

These are structures, not suggestions. The desk states what each one is exposed to and never which one to hold.
