# PosMgmt

Open position management: breakeven, partial closes by volume, and partial closes conditioned on indicators.

## Main features
- Breakeven by fixed points, ATR or risk/reward ratio (`CBreakEven`, `CBreakEvenSimple`, `CBreakEvenAtr`, `CBreakEvenRR`).
- Partial closes by volume/TP percentage across multiple stages (`CPartials`).
- Conditional partial closes, triggered by a pluggable condition (e.g. RSI) instead of a fixed level (`CConditionalPartials`, `CConditionalPartialsFactory`) — see [ConditionalPartial](./ConditionalPartial) for the class hierarchy.

## Basic usage

### Breakeven
```mql5
//--- Atr
atr_ultra_optimized.SetVariables(_Period, _Symbol, 0, 14);
atr_ultra_optimized.SetInternalPointer();

//--- Configure the breakeven values so it can be used
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 closes
```mql5
g_partials.AddLogFlags(InpLogLevelPartials);
g_partials.Init(InpMagic, _Symbol, InpVolumePercentageToClose, InpTpPercentagesForPartials);
```

### Conditional partial closes
```mql5
if(InpPartialsIsEnable)
  {
   // Atr creation
   g_atr = new CAtr();
   g_atr.Create(_Period, _Symbol, 14, true, true);
   g_atr.SetAsSeries(true);
   CAutoCleaner::AddPtr(g_atr); // auto-deleted on deinit

   // Dynamic instance from the factory
   g_partials = CConditionalPartialsFactory::Create(InpPartialsClassManagerType);
   g_partials.AddLogFlags(InpPartialsLogLevel);

   // RSI condition
   CConditionalPartialsIndRsi* rsi_condition = new CConditionalPartialsIndRsi();
   if(!rsi_condition.Init(InpPartialsRsiTimeframe, _Symbol, InpPartialsRsiPeriod, InpPartialsRsiOverBoughtLevel, InpPartialsRsiOverSoldLevel))
     return INIT_PARAMETERS_INCORRECT;

   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;

   if(!g_partials.Init(config))
     return INIT_PARAMETERS_INCORRECT;
   else
     CAutoCleaner::AddPtr(g_partials);
  }
```
