Market Direction

This script uses the ETF "VTI" to track the trend of the market
It requires 2 consecutive 5 day periods up or down to verify the direction otherwise the trend is neutral
It also uses a BB%B calculation to determine over bought and over sold conditions.
It will display numbers for 10 days ago, 5 days ago, downtrend today and uptrend today and finally the %B
