These Bollinger Bands are exponential because the variance is calculated using the exponential moving average, rather than just adding the normal standard deviation to the ema. This may be more useful because the exponential standard deviation should be more sensitive to near term increases or decreases in volatility.

I've been working on a top and bottom picker script over the past couple of weeks, based on RSI of multiple timeframe closing price. It've been a pretty good trading system that's tested over the last meteoric rise from 220~270 and back down to 230 right now, and I think it should be released to the community.
Sure, I'm not worried about this strategy not working...
You also need to add a MA30 to the chart and set a timeframe of W on FOREX and others and H4 or D for BTCUSD.
Buy: when MA30 changes from downtrend to uptrend, price is over MA30 and magarto indicator shows a crossover in the top.
Sell: opposite scenario
Update 1: Sorry, for LTCUSD it didn't work. I used the wrong chart when I published it so check it in BTCUSD.
