Three Typical Candles - MetaTrader 5용 expert

The EA only operates when a new bar appears within a specified time interval. It calculates the Typical prices for bars #1, #2, and #3. This results in getting trading signals:

   double typical_3=(rates[3].high+rates[3].low+rates[3].close)/3.0;
   double typical_2=(rates[2].high+rates[2].low+rates[2].close)/3.0;
   double typical_1=(rates[1].high+rates[1].low+rates[1].close)/3.0;

   if(typical_3<typical_2 && typical_2<typical_1)
      if(count_buys==0)
         m_need_open_buy=true;

   if(typical_3>typical_2 && typical_2>typical_1)
      if(count_sells==0)
         m_need_open_sell=true;

No more than one position is in the market at a time. A BUY open signal is also a SELL close one, and vice versa: A SELL open signal is a BUY close one (the algorithm is like this: First closing, and then opening).

I recommend testing it on timeframes starting from H1 and higher and on several symbols.
