More details

  • Fusion Scalper AI — User Guide
  • 1) What it is
  • A lightweight scalping EA combining:
  • • AI module (online perceptron) that learns from recent bars
  • • Trend filter with Moving Average
  • • Timing with Stochastic cross
  • • Volatility gate using Bollinger Bands Width
  • • Safety layers: spread filter, bar-cooldown, SL/TP, and trailing stop
  • It trades one position at a time per symbol/magic.
  • 2) How signals work (high level)
  • • AI score (from last closed bar) evaluates short-term direction using 5 features:
  • o bias (1.0), short return, MA slope, Stoch (K–D), BB width (relative to price).
  • • Filters (optional but on by default):
  • o MA filter: only buy above MA / sell below MA.
  • o Stochastic cross: K>D for buys (with a fresh cross), K<D for sells.
  • o BB width: must exceed a minimum relative width; optionally the width must be
  • expanding.
  • • Risk/Execution: If spread ≤ max and cooldown passed, open order with fixed lot or %
  • risk, set SL/TP, then manage trade with trailing stop.
  • 3) Parameter reference (all inputs)
  • Trading permissions & safety
  • • InpAllowLong / InpAllowShort – enable buy/sell directions.
  • • InpMaxSpreadPoints – maximum spread (in points, not pips) to allow trading.
  • o Tip: On 5-digit brokers, 10 points ≈ 1 pip.
  • • InpCooldownBars – minimum bars to wait after an entry before opening a new trade.
  • Position sizing & exits• InpUseRiskPercent – if true, lot size is computed from InpRiskPercent and SL
  • distance.
  • • InpRiskPercent – % of equity risked per trade (used only if above = true).
  • • InpFixedLot – fixed lot if percentage risk is off.
  • • InpSL_Points / InpTP_Points – stop loss / take profit distances in points.
  • Trailing Stop (optional)
  • • InpUseTrailing – on/off.
  • • InpTrailStartPoints – start trailing once floating profit ≥ this value (points).
  • • InpTrailStepPoints – modify SL only when the new SL improves by at least this step
  • (prevents spam).
  • • InpTrailDistancePoints – keep SL this many points behind price while trailing.
  • Moving Average
  • • InpMAPeriod / InpMAMethod / InpMAPrice – baseline trend filter.
  • o Default: EMA(50) on Close.
  • Stochastic
  • • InpStochK / InpStochD / InpStochSlow / InpStochMethod / InpStochPrice
  • o Default: 14 / 3 / 3, SMA, Low/High.
  • o Entry requires fresh cross in the trade direction when enabled.
  • Bollinger Bands (Width gate)
  • • InpBBPeriod / InpBBDeviations / InpBBPrice
  • o Width = Upper – Lower.
  • • InpUseBBWFilter – require minimum width.
  • • InpMinBBW_Relative – minimum relative width = (Upper−Lower)/Close, e.g. 0.003 ≈
  • 0.30%.
  • • InpRequireWidthExpand – if true, width[1] must be > width[2] (expanding volatility).
  • AI (online perceptron)
  • • InpUseAI – include AI score in decision.
  • • InpAI_Threshold – score gate: > +threshold for buys, < −threshold for sells.• InpAI_Learning – update weights on each new bar (uses only closed bars).
  • • InpAI_LearnRate – weight update step (0.01–0.1 typical).
  • • InpAI_MaxAbsWeight – caps absolute weight values to prevent runaway learning.
  • Resetting the AI: The EA initializes weights to zero on attach or re-attach. To “forget”
  • learning, remove the EA and attach again (or change timeframe/symbol then revert).
  • 4) Exact entry & exit logic
  • Entry (evaluated on the last closed bar)
  • A trade can open only if:
  • 1. Spread ≤ InpMaxSpreadPoints and cooldown passed and no position with the same
  • magic.
  • 2. Filters:
  • o MA filter (if on):
  • ▪ Buy if Close[1] > MA[1]; Sell if Close[1] < MA[1].
  • o Stochastic cross (if on):
  • ▪ Buy if K[1] > D[1] and previously (bar 2) K ≤ D.
  • ▪ Sell if K[1] < D[1] and previously (bar 2) K ≥ D.
  • o BB width filter (if on):
  • ▪ (Upper−Lower)/Close[1] ≥ InpMinBBW_Relative;
  • ▪ and if InpRequireWidthExpand = true → Width[1] > Width[2].
  • 3. AI gate (if on):
  • o Buy if AI score(shift=1) > +InpAI_Threshold.
  • o Sell if AI score(shift=1) < −InpAI_Threshold.
  • Exits
  • • Hard SL/TP on order open.
  • • Trailing stop (if on) manages SL as profit grows.
  • 5) Recommended presets (ready to use)Below are tuned baselines. Always forward-test and adjust to your broker’s point size, typical
  • spread, and commission.
  • A) EURUSD M5 — “Balanced”
  • • Risk/Trade mgmt:
  • o InpUseRiskPercent=false, InpFixedLot=0.10 (or 0.02–0.05 for small accounts)
  • o InpSL_Points=250, InpTP_Points=300
  • o InpUseTrailing=true, InpTrailStartPoints=200, InpTrailStepPoints=50,
  • InpTrailDistancePoints=150
  • • Filters:
  • o InpMaxSpreadPoints=20–25
  • o InpCooldownBars=5
  • o InpUseMAFilter=true (EMA50)
  • o InpUseStochCross=true (14/3/3)
  • o InpUseBBWFilter=true, InpMinBBW_Relative=0.0030,
  • InpRequireWidthExpand=false
  • • AI:
  • o InpUseAI=true, InpAI_Threshold=0.00
  • o InpAI_Learning=true, InpAI_LearnRate=0.05, InpAI_MaxAbsWeight=5.0
  • • Notes: Good day-to-day baseline; if entries feel sparse, lower InpMinBBW_Relative to
  • 0.0025.
  • B) EURUSD M5 — “Conservative”
  • • Lower risk & tighter filter = fewer but cleaner trades.
  • • InpFixedLot=0.05 (or InpUseRiskPercent=true, InpRiskPercent=0.5–0.8)
  • • InpSL_Points=300, InpTP_Points=300
  • • InpCooldownBars=7–8
  • • InpMinBBW_Relative=0.0035 and InpRequireWidthExpand=true
  • • InpAI_Threshold=0.10 (require stronger AI conviction)
  • • Trailing: Start=250, Step=70, Distance=180C) EURUSD M5 — “Aggressive”
  • • More trades; higher noise risk.
  • • InpFixedLot=0.10–0.20 (or InpRiskPercent=1.0–1.5 with % risk mode)
  • • InpSL_Points=200, InpTP_Points=250
  • • InpCooldownBars=3
  • • InpMinBBW_Relative=0.0020, InpRequireWidthExpand=false
  • • InpAI_Threshold=−0.05 ... +0.05 (essentially near zero gate)
  • • Trailing: Start=150, Step=40, Distance=120
  • D) XAUUSD (Gold) M5 — “Volatility aware”
  • • Gold has larger ranges and spreads—scale distances up.
  • • InpMaxSpreadPoints: set near your broker’s typical spread (e.g., 300–600 points on 2-
  • digit/3-digit gold symbols; check symbol specs)
  • • InpSL_Points=1500–2200, InpTP_Points=1800–2500
  • • Trailing: Start=1200, Step=300, Distance=900
  • • InpMinBBW_Relative=0.0040–0.0060
  • • InpCooldownBars=6
  • • EMA50, Stoch 14/3/3, AI default learning.
  • Important: Point sizes differ by symbol. Always open Specifications in MT5 (right-click the
  • symbol) to confirm digits and contract size.
  • 6) Tuning workflow (fast)
  • 1. Check spread: set InpMaxSpreadPoints just above your average spread on target
  • sessions.
  • 2. Entry rate: If too few trades → lower InpMinBBW_Relative, or turn off
  • InpRequireWidthExpand, or reduce InpCooldownBars.
  • Too many trades → increase Threshold, increase MinBBW_Relative, increase Cooldown.
  • 3. Profitability curve: If many small wins and occasional big losses → increase SL_Points
  • or start trailing earlier with slightly larger TrailDistance.
  • 4. AI behavior:o If learning is unstable: reduce InpAI_LearnRate to 0.02–0.03; keep
  • MaxAbsWeight=3–5.
  • o To “re-seed” learning: re-attach EA (weights reset to zero).
  • 5. Stochastic sensitivity: If you get whipsawed, consider StochK=21 (slower) or require
  • MA filter strictly on.
  • 7) Backtesting & forward testing
  • • Model: Every tick or 1-min OHLC for speed; keep timeframe consistent with your plan
  • (e.g., M5).
  • • Spread: Use current or a realistic fixed spread for the symbol.
  • • Commission: Set as per broker.
  • • Sample periods: Capture both ranging and trending regimes (at least 3–6 months).
  • • Walk-forward: After optimizing, validate on unseen data.
  • 8) Best practices
  • • Trade during liquid sessions (London/NY overlap) for tight spreads.
  • • Avoid major high-impact news if your broker widens spreads—use the spread filter as a
  • guard.
  • • One EA instance per symbol (unique Magic if you run multiple EAs).
  • • If your broker uses very small point values, scale SL/TP/Trailing proportionally.
