You can also do this in an easier way by:
Plot the original bollinger bands on a 30 min chart (say 20 period
bollinger bands)
Superimpose a second set of bollinger bands set to 20*14 = 280 periods
(14 = number of 30 min periods in 1 day)
Superimpose a third set of bollinger bands set to 20*14*5 = 1400 periods
(number of 30 min periods in 1 week)
Make sure you have enough days in your 30 min chart to cover at least 1
week of data.

Eduardo,
Plot the 30 minute data as data1 and the daily data as data2 and the
weekly data as data3. You can make data2 and 3 hidden if you don't want
to see them. The plot bollinger bands based on datas 2 and 3, but plot
them in subgraph 1. Make sure scaling is set to "same as price data".
