CryptoGuru Signals [v2018-08-25]

Built an all in one indicator providing buy / sell signals for CryptoGuru
from the ProfitTrailer trading bot discord as a Birthday Present for him.

Others on the discord seemed to like it so I am publishing it here for general use.

He made a request in our TradingView channel:

I'm looking to put together a buy signal for a 5 min time
frame that shows alerts me when a coin in BTC pairs. Is at
the lower of B.B. band or below the lower B.B. band combined
with RSI 30, and a 8/13 cross with the cross showing the coin
moving in up trend.

I made the indicator generic so it will work with any market, trading pair and timeframe.

You can select between ticker price / period or closing price.

The script uses multiple indicators including an EMA cross as its main signal and then optionally
makes use of RSI and Bollinger Bands to support the cross.

These individual indicators parameters can all be configured via the input screen and their colours
changed to suit your preference.

The display of the EMA lines is optional as is the display of the RSI and Bollinger Bands. The
signals will always display based on whatever input criteria you provide. If your input values
don't produce any signals then adjust them until they do.
