Market Chameleon is a serious research desk: covered-call and naked-put screeners, historical IV, and CSV downloads at $99/mo (verified 2026-09-23). But screeners end at the trade. Days to Expiry adds the missing half — live broker-synced roll-adjusted cost basis, per-leg P&L, and a weekly execution plan for $50/mo.
Market Chameleon is a browser-based options research subscription: covered-call and naked-put screeners with 15+ filters, historical implied volatility, earnings and dividend calendars, order-flow sentiment, and CSV downloads — Premium is $99/month with a 7-day trial (marketchameleon.com, re-verified 2026-09-23). If your question is 'what trades look interesting?', it answers well. If your question is 'what did my book actually do after I sold the put, rolled the call, and got assigned?' — screeners end where the portfolio begins. Days to Expiry is the market chameleon alternative for the second question: connect Interactive Brokers via Flex Query or 32+ brokers via SnapTrade, and every position syncs into roll-adjusted true cost basis, per-leg P&L, coverage views, and an auto-generated weekly execution plan. You keep income-focused scanning — including a free covered call screener with model assignment probability — and add the portfolio-truth layer a research desk doesn't provide.
