Utils/FA

Shared base classes used across the ecosystem: ATR access, bar control, auto-cleanup, simple logging, diffs and sorting.

Main features

ATR wrapper for indicator access (CAtr and related classes in Atr.mqh).
Bar-change detection helpers, including per-timeframe variants (CBarControler, CBarControlerFastW1, CBarControlerFastMN1, CBarControlerFastMinors).
Automatic pointer cleanup on deinit (CAutoCleaner).
Lightweight logging base used by other modules (CLoggerBase).
Distance/diff calculators — by points or by ATR (CDiff, CDiffPoint, CDiffAtr).
Simple array sorting (CSimpleSort).

CBarControler bar_ctrl;
bar_ctrl.Init(_Symbol, PERIOD_CURRENT);

if(bar_ctrl.IsNewBar())
  {
   // new bar logic
  }

CAtr* g_atr = new CAtr();
g_atr.Create(_Period, _Symbol, 14, true, true);
CAutoCleaner::AddPtr(g_atr); // will be deleted automatically on deinit

CDiffAtr* diff = CreateDiffptr(MODE_DIFF_BY_ATR, _Symbol, g_atr, 0, 1.5);

Only the most representative classes are shown here.
