What does the Pro plan unlock?

Real-time alerts (email, webhook, MCP), unmasked backtest, portfolio tracking, REST API at 600 req/min, and priority CSV exports.

Why this price

Cheaper than 2iQ, more markets than TipRanks.

TipRanks Premium is $29.95/mo and stays US-centric with no API. Quiver Trader climbs to $75/mo for the US only, with no MCP. GuruFocus Premium bills $449/yr. 2iQ Research and Smart Insider, the institutional gold standard, start north of several thousand dollars per seat per year (publicly undisclosed). Sigma Pro at €19/mo covers 28 live regulators with API and MCP, a slot no peer fills.
