BB 100 with Barcolors — Indicator by rmwaddelljr

I cleaned up the highlight barcolor to reflect red or lime depending if it closed > or < the open.

The description is in the code. you want to catch bounces off the 25 (upper or lower) and 100 (upper or lower).
Works well on the hourly and 30 min charts. Haven't tested it beyond that. Haven't tested Forex, just equities.

// BB 100 with Barcolors by Robert Waddell
// I came across an unusual Bollinger Band setup where they use 100 sma and a 25 (not 20) sma.
// I've seen it traded on a 1 hr chart.  I noticed that the combo (100 & 25) produced interesting
// results with bounces off the hourly chart.  you have to load the BB 25 with barcolors
// and the BB 100 with Barcolors seperately.  Also, repo32's "BuySellEMA" is included in the chart
// and provides 8EMA buy/sell signals.  If you see something that needs changing, go for it.
