### Overview

This is a trend following strategy based on the QQE (Qualitative Quantitative Estimation) indicator and moving averages. It determines the trend direction and generates trading signals based on fast QQE crosses filtered by the direction of moving averages.

The strategy can use three kinds of QQE crosses to determine the trading signal: (1) Smooth RSI crossing 0 line; (2) Smooth RSI crossing fast QQE line; (3) Smooth RSI exiting the RSI threshold channel. By default it uses the third cross to open position and the second cross to close position.

The buy and sell signals can choose to add an additional filter by moving averages: the close price should be above (below) the fast MA line, and the fast MA line should be above (below) the slow MA line, to generate a trading signal.

This strategy is suitable to be used in automated trading with signal-to-signal mode.

### Principle

The core indicator of this strategy is QQE. Its calculation formula is as below:

``````Wilders_Period = RSILen * 2 - 1

Rsi = rsi(close,RSILen)
RSIndex = ema(Rsi, SF)
AtrRsi = abs(RSIndex - RSIndex[1])
MaAtrRsi = ema(AtrRsi, Wilders_Period)
DeltaFastAtrRsi = ema(MaAtrRsi,Wilders_Period) * QQEfactor

newshortband = RSIndex + DeltaFastAtrRsi
newlongband = RSIndex - DeltaFastAtrRsi
``````

Where RSILen is the length period of RSI, and SF is the RSI smoothing factor. QQE is essentially a smoothed RSI. It calculates an upper and lower channel based on a fast ATR, and the crossing of price over the channel indicates buy or sell signals.

The strategy uses three kinds of QQE crosses to identify trading signals:

1. Smooth RSI crossing 0 line (XZ)
``````QQEzlong = RSIndex >= 50 ? QQEzlong + 1 : 0
QQEzshort = RSIndex < 50 ? QQEzshort + 1 : 0
``````
1. Smooth RSI crossing fast QQE line (XQ), like an early swing signal
``````QQExlong = FastAtrRsiTL < RSIndex ? QQExlong + 1 : 0
QQExshort = FastAtrRsiTL > RSIndex ? QQExshort + 1 : 0
``````
1. Smooth RSI exiting threshold channel (XC), like a confirmed swing signal
``````threshhold = 10
QQEclong = RSIndex > (50 + threshhold) ? QQEclong + 1 : 0
QQEcshort = RSIndex < (50 - threshhold) ? QQEcshort + 1 : 0
``````

One or multiple of the above three crosses can be selected to identify entry and exit signals.

``````// Filter condition
QQEflong = close > ma_medium AND
ma_medium > ma_slow AND
ma_fast > ma_medium

QQEfshort = close < ma_medium AND
ma_medium < ma_slow AND
ma_fast < ma_medium
``````

This helps avoid false signals in sideways markets.

The strategy is suitable for automated trading by using different QQE crosses for entries and exits:

``````Entry signal = XC OR XQ OR XZ
Exit signal = XQ OR XZ
``````

The advantages of this strategy include:

1. Using the QQE indicator to determine trend and cross signals. QQE itself has the characteristic of smoothing and noise reduction, which can decrease false signals.

2. Adding filter by moving averages can further avoid false signals in sideways markets and improve signal quality.

3. Choosing different QQE crosses for entry and exit enables automated trading.

4. The smooth RSI signal has lagging effect, so the buy/sell signals will not repaint.

5. The parameters can be optimized on different timeframes to find the best combination.

### Risks

There are also some risks of this strategy:

1. Wrong signals may occur during trend reversal. Stop loss should be set to control risks.

2. Inappropriate parameter settings can affect strategy performance. Multiple tests and optimizations are needed to find the best parameters.

3. Different symbols and timeframes need separate test and parameter tuning.

4. Mechanical trading has risks of drawdown and consecutive losses. Position sizing and risk management are necessary.

The corresponding solutions are:

1. Set stop loss to exit positions when loss reaches a certain amount.

2. Test different parameter combinations thoroughly to find the optimal parameters.

3. Adjust parameters according to symbol and timeframe characteristics.

4. Use proper capital management, scale-in positions, and control per trade position size.

### Optimization Directions

There are several directions that this strategy can be optimized:

1. Optimize QQE parameters including RSI length, RSI smoothing length, fast ATR length etc, to find the optimal parameter combination.

2. Optimize moving average parameters, adjust period, type etc to match best with QQE indicator.

3. Test different QQE crosses for entry and exit to find the most stable combination.

4. Fine tune parameters according to different symbols and timeframes. Use shorter periods for lower timeframes and intraday trading.

5. Add stop loss mechanism to stop out when loss reaches certain percentage.

6. Appropriately reduce position sizing and test different position management methods.

### Conclusion

This strategy integrates using the QQE indicator for judging trend and crosses, and the moving average for filter, to generate trading signals. During live trading it can be optimized by adjusting parameters to improve signal quality, and by strict money management to control risks. The strategy suits automated trading with signal-to-signal mode, and can also aid discretionary trading. Further optimizations on logics and parameters can make it adaptable to more market conditions.

// Author:  JustUncleL
// Date:    10-July-2016
// Version: v6, Major Release Nov-2018
//
// Description:
//  A following indicator is Trend following that uses fast QQE crosses with Moving Averages
//  for trend direction filtering. QQE or Qualitative Quantitative Estimation is based
//  on the relative strength index (RSI), but uses a smoothing technique as an additional
//  transformation. Three crosses can be selected (all selected by default):
//    - Smooth RSI signal crossing ZERO (XZ)
//    - Smooth RSI signal crossing Fast QQE line (XQ), this is like an early warning swing signal.
//    - Smooth RSI signal exiting the RSI Threshhold Channel (XC), this is like a confirmed swing signal.
//      An optimumal Smooth RSI threshold level is between 5% and 10% (default=10), it helps reduce
//      the false swings.
//  These signals can be selected to Open Short/Long and/or Close a trade, default is XC open
//
//  The (LONG/SHORT) alerts can be optionally filtered by the Moving Average Ribbons:
//    - For LONG alert the Close must be above the fast MA Ribbon and
//        fast MA Ribbon must be above the slow MA Ribbon.
//    - For SHORT alert the Close must be below the fast MA Ribbon and
//        fast MA Ribbon must be below the slow MA Ribbon.
//  and/or directional filter:
//    - For LONG alert the Close must be above the medium MA and the
//      directional of both MA ribbons must be Bullish.
//    - For SELL alert the Close must be below the medium MA and the
//      directional of both MA ribbons must be Bearish.
//
//  This indicator is designed to be used as a Signal to Signal trading BOT
//  in automatic or semi-automatic way (start and stop when conditions are suitable).
//  - For LONG and SHORT alerts I recommend you use "Once per Bar" alarm option
//  - For CLOSE alerts I recommend you use "Once per Bar Close" alarm option
//  (* The script has been designed so that long/short signals come at start of candles *)
//  (* and close signals  come at the end of candles                                    *)
//
// Mofidifications:
//  6.0 - Major Release Version
//      - Added second MA ribbon to help filter signals to the trend direction.
//      - Modified Alert filtering to include second MA Ribbon
//      - Change default settings to reflect Signal to Signal BOT parameters.
//      - Removed older redunant alerts.
//
//  5.0 - Development series
//
//  4.1 - Fix bug with painting Buy/Sell arrows when non-repaint shunt mode selected.
//      - Added Long and Short Alarms. When combined with the "first Buy/Sell" in trend option,
//        It is now possible to use this indicator to interface with AutoView
//        or ProfitView. I suggest using the "QQEX XZ Alert" alarm to exit Long or Short
//        trade. Use only "Once per bar Close" option for Alarms. This is not a full
//        fledged trading BOT though with TP/SL settings.
//
//      - Changed QQE defaults to be a bit smoother (8, 5, 3) instead of (6, 3, 2.618).
//
//      - Changed defaults to use HullMAs instead of EMAs.
//        Alert is displayed. The alarm is still generated on the previous candle so you can
//        still get a pre-warning, this enables you time to analyse the pending alert.
//        and show simple stats: success rate and number of trades (out of 5000), this will help
//        tune the settings for timeframe and currency PAIR.
//  2.0 - Added code to use the medium moving average (EMA20) rising/falling for additional
//        trend direction filter.
//      - Remove Moving Average cross over signals and other options not used in this indicator.
//      - Added code to distinguish between the crosses, now only show Thresh Hold crosses as BUY/SELL
//      - Modidied default settings to more well known MA's and slightly different QQE settings, these
//        work well at lower timeframes.
//  1.0 - original
