double bollinger bands

2. added option to hide bollinger bands.
3. added second level of visual alert (red marks vs yellow marks for first level check).
first level visual alert is correct 8 times out of 10.
second level visual alert is more rare, yet is correct 9 times out of 10.
again, these signals work best on 1m and 5m time frames.
