14. Pyramiding (Position Scaling)

Inp_Pyramid_Multiplier = 3.0 // Scale multiplier (probe → main) Inp_Pyramid_Max_Lots = 2.0 // Hard cap: max lots for any single position Inp_Pyramid_OnlyProfitable = true // Pyramid only if last position is in profit

Logic:

No open positions: lots = target_lots / 3.0 — a small probe is opened (1/3 of normal)

Position exists: lots = last_volume × 3.0 — scaling up to full size

If OnlyProfitable = true and the last position is in loss → pyramid is blocked

Log: "Pyramid blocked: last position not in profit." / "LOT CAP: 4.50 -> 2.00"

13. Capital Management & Position Sizing

Capital Modes (ENUM_CAPITAL_MODE)

Mode	Description
`CAPITAL_COMPOUND_AUTO`	Base = account balance (automatic)
`CAPITAL_FIXED_MANUAL`	Base = `Inp_Fixed_Capital_Amount` (fixed)
`CAPITAL_COMPOUND_AUTO` + `Inp_Compound_Enable=true`	Base = Fixed + g_CompoundBuffer (from TXT file)

Position Sizing Algorithm (CalculatePositionSize)

1. base_capital = [depending on mode]
2. budget       = base_capital × MaxTotalMarginPercent / 100
3. risk_money   = budget × Risk_Percent_Per_Trade / 100
4. sl_ticks     = (Hard_SL_Points × _Point) / tick_size
5. loss_for_one_lot = sl_ticks × tick_value
6. target_lots  = risk_money / loss_for_one_lot

→ First position:      target_lots / Pyramid_Multiplier  (probe — smaller)
→ Subsequent position: last_volume × Pyramid_Multiplier  (main — larger)

7. Round to broker's volume step
8. Enforce broker's min/max volume
9. Check hard cap: Max_Lots
10. Margin check: OrderCalcMargin → if budget exceeded → abort

Compound Buffer

g_CompoundBuffer is read from an external TXT file. Allows percentage-based growth of the capital base at configurable intervals: Daily / Weekly / Monthly. Enables a compound interest effect on a locked base without changing EA settings.
