After a big gap up the market generally continues in that direction for the first 5-10 minutes. Then it generally tries to fill 50% of the gap. So mark yesterdays close and the first 15 min spx candle to measure the move. Then check breadth and advance decline numbers. If the pullback is less than 50% it is a strong market and will continue the strong up day. If it breaks the 50% level it will then attempt to fill the gap. A sideways move means hold longs till at least the afternoon.
FAS I got in way too early (EOD thursday). The market is correcting my poor entry point.
My thinking is gap and crap. However catching the bears so off guard will give this some juice. If breadth and advance decline stay strong stay long. I will post a chart after 10am
