BB 25 with Barcolors — Indicator by rmwaddelljr

6/19/15 I added confirmation highlight bars to the code. In other words, if a candle bounced off the lower Bollinger band, it needed one more close above the previous candle to confirm a higher probability that a change in investor sentiment has reversed. Same is true for upper Bollinger band bounces. I also added confirmation highlight bars to the 25 sma (the basis). The idea is that lower and upper bands are potential points of support and resistance. The same is true of the basis if a trend is to continue. Nothing moves in a straight line. As with any indicator, it is a tool to be used in conjunction with the art AND science of trading. As always, try the indicator for a time so that you are comfortable enough to use real money. This is designed to be used with "BB 100 with Barcolors"

// BB 25 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.
