// Title:   [STRATEGY][UL]QQE Cross v1.1
// Author:  JustUncleL
// Date:    22-Oct-2016
// Version: v1.1
//
// Description:
//  A trend following trading Strategy that uses fast QQE crosses with Moving Averages
//  for trend direction filtering. QQE or Qualitative Quantitative Estimation is based 
//  on the relative strength index, but uses a smoothing technique as an additional 
//  transformation. Three crosses can be selected (all selected by default): 
//    - RSI signal crossing ZERO (XZERO)
//    - RSI signal crossing Fast RSIatr line (XQQE)
//    - RSI signal exiting the RSI Threshhold Channel (BUY/SELL)
//  The (BUY/SELL) alerts can be optionally filtered by the Moving averages:
//    - For BUY alert the Close must be above the fast MA and 
//        fast MA (EMA8) > medium MA (EMA20) > slow MA (SMA50).
//    - For SELL alert the Close must be below the fast MA and
//        fast MA (EMA8) < medium MA (EMA20) < slow MA (SMA50).
//  and/or directional filter:
//    - For BUY alert the Close must be above the slow MA (SMA50) and the
//      directional MA (EMA20) must be green.
//    - For SELL alert the Close must be below the slow MA (SMA50) and the
//      directional MA (EMA20) must be red.
//. The XZERO and XQQE are not included in the filtering, they are used to indicate
//  pending BUY/SELL alerts, particularly the XZERO. 
//
//  This Strategy should work on any currency pair and most chart timeframes.
//  *** USE AT YOUR OWN RISK ***
//  
// 
//
// Mofidifications:
//  1.1 - Added Target Profit option, cleaned up the risk management code.
//        Changed Trade Close to EMA20 direction change instead of opposite BUY/SELL
//        signal, which will be earlier, this means stop loss setting should not be
//        required when an AutoTrader is available.
//        Modified code to prevent potential repaint issues.
//  1.0 - original
