【解説】【MQL5 community】 The Universal Moving Average : Custom Moving Averageと同様。

【シグナル】
移動平均のラインを上抜けしたら、「買い」、下抜けしたら「売り」。 上昇基調になりそうな(移動平均が右肩上がり)場合のトレンドを把握することができる。

/*
   The Universal Moving Average, 
   it allows to select any type of moving average, included in the MetaTrader 5 client terminal.
   
   Simple,
   Exponential,
   Smoothed,
   Linear Weighted,
   AMA (Adaptive Moving Average),
   DEMA (Double Exponential Moving Average),
   FRAMA (Fractal Adaptive Moving Average),
   TEMA (Triple Exponential Moving Average),
   VIDYA (Variable Index DYnamic Average).  
   
   Main parameters:
   
   MAMethod - MA type, 
   MAPeriod - period,
   MAPrice - applied price.
   
   Additional parameters:
   
   AMAFast - period of fast EMA for AMA,
   AMASlow - period of slow EMA for AMA,
   CMOPeriod - period of CMO for VIDYA. 

   The name of MA, its period, applied price and other parameters are shown in the popup help.
