[ HOW IT WORKS ]
The overlay replaces the usual options-tape staring contest. Instead of reading a put-call ratio table, you see the chart with the levels that actually constrain price.
Rails are recomputed intraday as open interest shifts and as the term structure updates. The overlay re-anchors automatically.
A single keystroke toggles between expiry-weighted, all-expiries, and a single-expiry projection — useful for OPEX days where one chain dominates.
