ALAMO Hotfix5 — Account DD + Array List Fire

🐛 Root cause — 3 bugs phát hiện

🔒 SS Directives (locked)

📋 6 Phases

🔧 Key code changes

1. AlamoCurrentDDPct — Account DD formula

double AlamoCurrentDDPct()
{
   if(g_alamoEquityAnchor <= 0) return 0.0;
   double sumNeg = 0.0;
   for(int i=0; i<PositionsTotal(); i++) {
      ... // iterate main grid neg PnL
   }
   return (MathAbs(sumNeg)
           / g_alamoEquityAnchor) * 100.0;
}

double AlamoCurrentDDPct()
{
   double balance = AccountInfoDouble(
      ACCOUNT_BALANCE);
   double equity = AccountInfoDouble(
      ACCOUNT_EQUITY);
   if(balance <= 0) return 0.0;
   double dd = ((balance - equity) /
                balance) * 100.0;
   return MathMax(dd, 0.0);
}

2. checkAbove direction — flip per SS dominant spec

// L1=SELL → ABOVE; L1=BUY → BELOW
bool checkAbove =
   (lnType == POSITION_TYPE_SELL);

// BUY dom (L1=SELL) → BELOW
// SELL dom (L1=BUY) → ABOVE
bool checkAbove =
   (lnType == POSITION_TYPE_BUY);

3. Fire condition — Array List model

case ALAMO_S3_MONITOR:
{
   if(!AlamoCon1AllNegative(...))
      { fall back to S2; }    // full grid
   if(ddNow < fireGate) return;
   double lotSum =
      AlamoSum2CondLots(L1_ticket);
   if(lotSum <= 0) return;
   AlamoFire(opp, lotSum, ...);
}

case ALAMO_S3_MONITOR:
{
   if(!g_alamoPrevCache.valid) return;
   if(ddNow < fireGate) return;
   int qualCount = AlamoCount2CondOrders(
      cache.priceOpen, cache.type);
   if(qualCount <= 0) return;
   // Array List by construction all-neg
   double lotSum = AlamoSum2CondLots(...);
   AlamoFire(opp, lotSum, ...);
}

📦 Array List of Ln — fire flow

Khi Ln-1 fire, ALAMO bắt đầu build Array List của Ln:

1. Direction check: đo dominant side của main grid
2. Anchor: prevLn (L1 cho L2, L2 cho L3, ...)
3. Filter orders:
   • BUY dom → orders BELOW prevLn (giá rớt thêm)
   • SELL dom → orders ABOVE prevLn (giá tăng thêm)
   • Symbol = current, Magic = main grid (123456), Volume > 0.01 (skip Skill 6), PnL < 0
4. Index 0 của Array List = order đầu tiên trên/dưới prevLn theo direction
5. Monitor loop mỗi tick:
   • Nếu DD < N×Thr → continue (không fire)
   • Nếu DD ≥ N×Thr AND qualCount > 0 → fire Ln
6. Recursive cho L3, L4... với prevLn anchor

✅ Verify checklist (Phase 6 backtest)

• Init log: FBot Hotfix5: AccountDD=true | balance=X | equity=Y | accountDD=Z%
• L1 fire: account DD ≥ 10.00%
• L2 fire: account DD ≥ 20.00%
• L3 fire: account DD ≥ 30.00% (nếu reach)
• L2/L3 anchor = prevLn ticket (KHÔNG L1-fixed)
• qualCount > 0 trên mỗi fire event
• UI Row 2 DD match ALAMO panel header DD trên screenshot
• No AlamoS3MonitorOffset references trong log/code
