Multi Arbitration 1.1xx - expert for MetaTrader 5

A further development of Multi Arbitration 1.000.

Difference from 1.000:

• The EA is only launched on PERIOD_M1 (see the explanation below, parameter Time frame).

• The EA now trades two symbols simultaneously. The second symbol is taken from the ExtArrSymbols static array:

  string         ExtArrSymbols[20]=
    {
     "EURUSD","GBPUSD","USDCHF","USDJPY","USDCAD",
     "AUDUSD","AUDNZD","AUDCAD","AUDCHF","AUDJPY",
     "CHFJPY","EURGBP","EURAUD","EURCHF","EURJPY",
     "EURNZD","EURCAD","GBPCHF","GBPJPY","CADCHF"
    };

  //| Expert initialization function                                   |
  //+------------------------------------------------------------------+
  int OnInit()
  

• Position opening principle has changed:

  • Now, a new BUY position can only be opened when the current price is below the lowest BUY position.
  • A new SELL position can only be opened when the current price is above the highest SELL position.

  

• The new parameter Time frame allows optimizing the EA on any chart. The Expert Advisor works when a new bar of the main symbol appears (i.e. the symbol of the chart on which the EA is running):

  //+------------------------------------------------------------------+
  //| Expert tick function                                             |
  //+------------------------------------------------------------------+
  void OnTick()
    {
  //--- we work only at the time of the birth of new bar
     static datetime prevtime=0;
     datetime time_0=iTime(0,m_symbol_one.Name(),InpTimeFrame);
     if(time_0==prevtime)
        return;
     prevtime=time_0;
  

  Here the InpTimeFrame variable is our Time frame input. Depending on the Time frame input, we can enable the EA to work on any timeframe!
