//|The idea was from Ron's bolltrade EA                                        |
//|He is a genius                                                              |
//|To avoid confusion, let me tell first:                                      |
//|This proposed trading system is different from Ron's bolltrade EA.          |
//|So do not try to match the entries from this proposed system                |
//|with Ron's Bolltrade entries.                                               |
//|Althought the idea of this proposed system was inspired by Ron's EA,        |
//|they are not matched, you may get confused                                  |

//+----------------------------------------------------------------------------+
//+----------------------------------------------------------------------------+
//|How to use this indicator into a trading system:                            |
//+----------------------------------------------------------------------------+
//|First is to determine decreasing volatility,                                |
//|place an ATR(30) on a >>>>15min<<<<< chart                                  |
//|Then overlay an SMA(30) on that ATR window.                                 |
//|When the ATR itself below its SMA,                                          |
//|then we have a decreasing volatility                                        |
//+----------------------------------------------------------------------------+
//|When we have decreasing volatility, we trade the range.                     |
//|That means: selling the top and buying the bottom.                          |
//|There are 2 kinds of top/bottom.                                            |
//|Example for top (bottom is the reverse):                                    |
//+----------------------------------------------------------------------------+
//|1st kind of top is:                                                         |
//|When the previous bar breaks the upper bollinger (green) band               |
//|and the current bar's high is not higher than the previous bar's high       |
//|Rules for selling this 1st kind of top:                                     |
//|Sell at next bar. Place limit sell order at current bar's pivot (H+L)/2     |
//+----------------------------------------------------------------------------+
//|2nd kind of top is:                                                         |
//|When the bar is touching the ATR (Blue) band                                |
//|Sell at market.                                                             |
//+----------------------------------------------------------------------------+
//|Initial SL is 4*ATR(500).                                                   |
//|For example: for eurusd, it will be arround 4*6 = 24 pips                   |
//|For gbpusd, it will be around 4*9 = 36 pips                                 |
//+----------------------------------------------------------------------------+
//|Exit trade when price touching either one of these levels:                  |
//|Exit #1: the level where the bollinger band is WHEN THE TRADE WAS ENTERED   |
//|Exit #2: moving average (middle bollinger band) that moves along the way    |
//+----------------------------------------------------------------------------+
//|                                                                            |
//|                                                                            |
//|Money Management ( VERY IMPORTANT!! )                                       |
//|"Risk 2% for each trade". What does this mean ?                             |
//|When having a 20pips SL and a 10k account,                                  |
//|a loss of 20 pips should decrease the account by a $200                     |
//|this will allow a $ 100,000 position = 1 standar lot = 10 mini lot          |
//|                                                                            |
//|                                                                            |
