I really think you'd benefit from understand how a bollinger band works first of all, once you grasp the idea of 'volatility' and how bollinger bands measure it in a variety of ways. You'll be able to comfortably use any length.
BUT the data varies from time frame to time frame, for example a 200 length on the 1hour timeframe, should be 100% the same as the 50 length on the 4 hour right? Sure they MIGHT be exactly the same, but the 1H time frame may have experienced something that's invisible on the 4H time frame.

Look at this example here.
>Ioaded the 1h chart with 200 length BB
>loaded the 4h chart with 50 length BB

If you can read the indicator values (the labels on the right hand side) you'll notice that price varies EVER so slightly. Take a look for yourself by opening up a 50 length 4h BB and a 200 length 1h BB if you want.
