1. Failed Impulse Sell

Generally, after a market makes a new price, momentum, and TICK (market internals) low, we would expect lower prices yet to come. A good trade set-up – that I call the “Impulse Sell” – occurs when price rallies into resistance after a sharp downward thrust. We expect lower prices ahead.
2. Rounded Reversal Formation
3. “Kick-off” Sign of Strength
4. Bollinger Band and 50 period EMA Breakout

I’m not sure this gave you much of a ‘warning’ but it was the final signal needed – the final nail in the bearish coffin for the day – that odds strongly favored a reversal. This was your execution signal to get long – or take your stop-losses if you remained in an intraday short-sale position.
