FINRA replaced the Pattern Day Trader rule with intraday margin. Bob Iaccino explains what changed, what IML and IMD mean, and what day traders should do now.

A Level 2 quote shows the order book: bid and ask depth, sizes, and participant IDs beyond the best price. How traders read depth, order flow, and the ax.

Bob Iaccino's 3X Profit Protection Rule: when realized profit hits three times your daily risk unit, stop trading or cut size, and keep the good days good.

Bob Iaccino explains what separates a high-probability breakout from a false one — why confirmation of the retest is the real signal, where the stop belongs, and the three entry points most traders get wrong.

A scanner tech stack is the combination of data feeds, filters, alerts, and timeframes a trader can layer into a single screening system. Instead of acting on one indicator in isolation, a well-built trading stack typically includes a signal to confirm across multiple conditions and timeframes before you commit capital. No single tool gets you there — the edge is in the architecture. Here’s how to build effective scanner setups for technical screening, layer by layer.

A stock screener filters the full universe of listed stocks against static or end-of-day criteria to build a watchlist before you trade. A stock scanner monitors live market data during the session and flags stocks the moment they meet your conditions. In short: a screener tells you what to watch. A scanner helps you evaluate when to act.
