    Sharks I have placed 20 unit bollinger bands on my chart but they do not get closer as the stock becomes more attractive to a break upwards. Can you assist me with this ?
    I also have Lead+/Lag- and Std deviations= numbers on my bollinger band set-up ...... do I need to tweak these numbers,they are currently set at 20 & 10.
    Cheers
