ⓘ How SL & lots are computed (capital-anchored)
Each alert deploys up to ₹50,000 of capital (lots × lot_size × entry premium).
The initial SL = 10% of capital deployed, translated back to a per-unit premium drop.
The Trail column shows the active step-down tier: 🟡 5% / 🟢 3% / 🔒 2%, ratcheting tighter as MFE grows.
When the trail ratchets the SL above the entry (BUY) or below (SELL/PE), the SL ₹ cell flips green and shows locked profit instead of pending risk.
5-lot example (LTF 260PE @ ₹2.05): lot_size 1,100 → qty 5,500 → capital ₹11,275 → max loss ₹1,128 (10%) → SL ₹1.84.
