These are the worst of all gaps to trade, what I call "inside" gaps.

How to spot them: these are gaps that occur inside the prior day's high/low range.

Why they're bad: because they don't have institutional volume trades behind them, so they often chop around, despite initial 1/2 point up to 1 point inside gap moves.

Instead, focus on >1-point gap continuation (and rare fade) plays, as discussed in other threads.

Here's another one, from AAPL. Normally AAPL's a top trading stock, at least it has been this past 4-6 months. But I personally avoid interior/inside gaps like this because they're just so darn unpredictable. I prefer to wait to "take a bite out of AAPL" til it's moved outside prior day's high/low.
