  • % EMA200 mac dinh (InpTrendBufferPercent = 0.10%), hoac
  • ATR-based neu InpUseATRTrendBuffer = true.
• InpSkipFlatEMA200: bo qua khi EMA200 phang (delta giua 2 nen <= ATR * InpFlatEMA_ATRMult).

2.3 4 trang thai

State	Y nghia
STATE_NO_TRADE	khong co setup hop le

Mode	Cong thuc
SL_SWING	swing extreme +/- InpSL_SwingBufferPoints
SL_ATR	Entry +/- ATR * InpSL_ATRMult
SL_HYBRID	chon SL rong hon giua swing va ATR (an toan hon, mac dinh)

2.8 Take Profit

• TP = Entry +/- R * InpRiskRewardRatio (mac dinh 2R).
