//
// Rhapsodyy's Combo Indicator v6
//
//  So to get around the indicator limit built within trading view i've combined
//  a bunch of the things i use to save on the indicator count.
//
//  I should think there's neater ways to write some of the code and there may be old code ive
//  left in and havn't cleaned up but everything should work as intended.
//
//  Items Included:
//
//  Simple Moving Averages (SMA):
//  These can be changed to any figures or colors you may prefer to use.
//  And can be individually or as a whole group turned on and off through settings.
//  10  - Purple - #8A2BE2
//  30  - Cyan - #00FFFF
//  50  - Olive - #556B2F
//  80  - Gold - #DAA520
//  200 - Maroon - #800000
//
//
//  Exponential Moving Averages (EMA):
//  These can be changed to any figures you may prefer to use.
//  And can be individually or as a whole group turned on and off through settings.
//  21  - Blue - #4682B4
//  50  - Green - #00FF00
//  89  - Yellow - #FFFF00
//  200 - Orange - #FF7F00
//  377 - Red - #FF0000

//  Bollinger Bands - With Included Buy and Sell Signals Following the Below Strategy
//
//
// Description:
// ============
// This indicator is an implementation of the Bollinger Band and EMA system.
// Id say have a look at it on the chart and see how it performs on different timeframes
// and you'll start to get the idea how it works. Then i start to include signals from MA/EMA's to look for targets or other factors.
//
//
//
// Here's the strategy:
// --------------------
// Going LONG:
// Enter a long position when the black 3 EMA has crossed up through the Bollinger red
// middle band MA.This is indicated by "Buy" alert.
//
// Going SHORT:
// Enter a short position when the black 3 EMA has crossed down through the Bollinger red
// middle band MA.This is indicated by the "Sell" Alert.
//
//  Stop Loss Ideas:
//  The Low (Long) or High (Short) of the candle that printed a buy or sell signal, or the previous candle.
//  This could depend on how tight the price action was and how much risk you wanted to take.
//  Possible to make a Trailing Stop loss? Or move Stop loss up if first targets hit?
//
//  Take Profit Ideas:
//  Basic % target, this may be more viable on higher time frames.
//  After a signal, targeting a MA/EMA, BB Band.
//  As entry and exit signals wont catch exact tops and bottoms, being able to refine the exit signal to fire
//  of another input than this Bollinger Strat may be more beneficial.
//
//  Increasing Position Size:
//  Example: On a Long Entry If candle following signal decreased in price but remained above stop loss at close,
//  Could increase position size.
//
//
// HINTS: Best trades tend to occur when price reversing bounce off outer band and
// and outside Optional Bollinger Squeeze indication.
