If anybody is interested...toby crabel thinks that if there is a narrow range bar (the market's range is much narrower than the previous 4-7+days) and then the next day the market gaps up above/below yesterday's high/low (say by 1 percent), you've got a good chance that the stock will run up for a while. If there is high volume and the stock runs up for 5-10 minutes, then it's probably even better. Natalie, if you can test that, I'll send you some flowers.
better to use 1 day! If I find a large range day followed by a single narrow range day (less than half of the previous day), I look for a continuation in same direction as large bar on the third day. Not backtested, just an observation... I am sure Fibonacci would agree
