Main features

RM

Oco order

COcoOrder oco;

void Function() 
{
 .
 .
 unsigned long ticket1 = trade.ResultOrder();
 .
 .
 unsigned long ticket2 = trade.ResultOrder();

 oco.AddOrders(ticket1,ticket2);
}  

Risk management

CRiskManagement rm;
// Note: "rm" requires that the lot, type, maximum profit and loss be reset, etc., before calling functions like CalculateSL, GetLote, etc.

// Check superated
if(g_loss_profit_manager.MaxLossIsSuperated())
  {
   risk.CloseAllPositions();
   CanTrade = false;
  }

// Calcule lot size
double entry_price = 1000.0;
double l = risk.GetLote(ORDER_TYPE_BUY, entry_price, 100, 0);   

// Calcule SL
long sl = risk.GetSL(ORDER_TYPE_BUY, entry_price, 100, 0)

// And more (GetPositionsTotal, SetStopLoss, CloseAllOrders, GetPositions, etc..)

Strategy

Basic configuration

  CAtrUltraOptimized* atr_ultra = new CAtrUltraOptimized();
  atr_ultra.SetVariables(PERIOD_CURRENT, _Symbol, 0, 14);
  atr_ultra.SetInternalPointer();
  strategy.AddLogFlags(InpStrategyLogLevel); // Log Flags
  strategy.SetAtrTP_SL(atr_ultra, INP_STRATEGY_ATR_MULTIPLIER_TP, INP_STRATEGY_ATR_MULTIPLIER_SL); // TP sl by atr
  strategy.SetOperateMode(TR_BUY_SELL, INP_STRATEGY_TYPE_TPSL);    // Operate mode 
  strategy.SetTP_SL(INP_STRATEGY_SL_POINT, INP_STRATEGY_TP_POINT); // TP SL by point
  if(InpRmLoteType == Fijo)
    strategy.FixedLotSize(InpRmLote); // Fixed lot size

Filters

// Filter RSI
  if(INP_FILTER_RSI_ENABLE)
   {
    CSFilterRsi* f = new CSFilterRsi();
    strategy.AddFilter(f);
   }

// Filter Stochastic
  if(INP_FILTER_STOCH_ENABLE)
   {
    CSFilterStochastic* f = new CSFilterStochastic();
    strategy.AddFilter(f);
   }

// Filter Bollinger Bands
  if(INP_FILTER_BANDS_ENABLE)
   {
    CSFilterBands* f = new CSFilterBands();
    strategy.AddFilter(f);
   }

// Codigo
  g_strategy_filter_general_parser.AddLogFlags(InpFIlterLogLevel);
  strategy.CodeCompra<CStrategyFilterEmptyFuncFac>(StringFormat("#group oAnd (%s,%s,%s,%s,%s,%s,%s) == 0 oAnd ([%s] == 0 oOr [%s] == 2)",
      CSFIlterAD_NAME, CSFilterSuperTrend_NAME, CSFilterFvg_NAME, CSFilterBands_NAME, CSFilterRsi_NAME, CSFilterStochastic_NAME, CSFilterLiqEstimed_NAME, CMediationsByZoneFilterName, CMediationsByZoneFilterName), 5);
  strategy.CodeVenta<CStrategyFilterEmptyFuncFac>(StringFormat("#group oAnd (%s,%s,%s,%s,%s,%s,%s) == 1 oAnd ([%s] == 1 oOr [%s] == 2)",
      CSFIlterAD_NAME, CSFilterSuperTrend_NAME, CSFilterFvg_NAME, CSFilterBands_NAME, CSFilterRsi_NAME, CSFilterStochastic_NAME, CSFilterLiqEstimed_NAME, CMediationsByZoneFilterName, CMediationsByZoneFilterName), 5);

// Summary
  strategy.PrintFilters();

Position management

Breakeven

//--- Atr
  atr_ultra_optimized.SetVariables(_Period, _Symbol, 0, 14);
  atr_ultra_optimized.SetInternalPointer();

//--- We set the breakeven values so its use is allowed
  break_even.SetBeByAtr(InpBeAtrMultiplier, InpBeAtrMultiplierExtra, GetPointer(atr_ultra_optimized));
  break_even.SetBeByFixedPoints(InpBeFixedPointsToPutBe, InpBeFixedPointsExtra);
  break_even.SetBeByRR(InpBeRrDbl, InpBeTypeExtraRr, InpBeExtraPointsRrOrAtrMultiplier, GetPointer(atr_ultra_optimized));
  break_even.SetInternalPointer(InpTypeBreakEven);
  break_even.obj.AddLogFlags(InpLogLevelBe);

Partial closures

  g_partials.AddLogFlags(InpLogLevelPartials);
  g_partials.Init(InpMagic, _Symbol, InpVolumenQueSeQuitaraDeLaPosicionEnPorcentaje, InpPartesDelTpDondeSeTomaraParciales);

Conditional partial closures

 if(InpPartialsIsEnable)
   {
    // Atr creation
    g_atr = new CAtr();
    g_atr.Create(_Period, _Symbol, 14, true, true);
    g_atr.SetAsSeries(true);
    CAutoCleaner::AddPtr(g_atr); // Añadimos para que se auto elimine


    // We assign to g_partilas the dynamic instance returned by CConditionalPartialsFactory::Create(...)
    g_partials = CConditionalPartialsFactory::Create(InpPartialsClassManagerType); // Sera elimnado globalmente

    // Initial log flags
    g_partials.AddLogFlags(InpPartialsLogLevel);

    // Create condition
    CConditionalPartialsIndRsi* rsi_condition = new CConditionalPartialsIndRsi(); // True dado que sera eliminado por partials

    // Rsi condition config
    if(!rsi_condition.Init(InpPartialsRsiTimeframe, _Symbol, InpPartialsRsiPeriod, InpPartialsRsiOverBoughtLevel, InpPartialsRsiOverSoldLevel))
      return INIT_PARAMETERS_INCORRECT;

    // Condition config
    ConditionalPartialConfig config;
    config.condition = rsi_condition;
    config.min_distance_to_close_pos = CreateDiffptr(MODE_DIFF_BY_ATR, _Symbol, g_atr, 0, InpPartialsMinDistanceInAtrMul);
    config.str_percentage_volume_to_close = InpPartialsVolumeToClosePercentage;
    config.magic_number = InpMagic;

    // Init partials
    if(!g_partials.Init(config))
      return INIT_PARAMETERS_INCORRECT;
    else
      CAutoCleaner::AddPtr(g_partials); // Añadimos al cleaner

    if(InpPartialsClassManagerType == CONDITIONAL_PARTIAL_CLASS_TYPE_CONSTANT)
     {
      CConditionalPartialsConst* partial = (CConditionalPartialsConst*)g_partials;
      partial.ForzeToClose(true);
     }
   }
