PrecisionScalper EA

Automated trading Expert Advisor for MetaTrader 5 — Forex & Gold scalping with real-time Telegram notifications and a live performance dashboard.

---

Overview

PrecisionScalper is a fully automated MQL5 Expert Advisor designed for intraday scalping on major Forex pairs and Gold (XAUUSD). It combines a multi-indicator signal logic with dynamic risk management and a real-time notification pipeline via Telegram.

Built from scratch as a personal project, the EA runs 24/5 on a VPS and pushes trade alerts directly to a dedicated Telegram channel. A custom HTML dashboard aggregates performance metrics in real time.

Features

• Signal logic — EMA 9/21 crossover confirmed by RSI filter (avoids low-momentum entries)
• Session filter — Active only during London and New York sessions (08:00–17:00 UTC) to target high-liquidity windows
• Dynamic risk management — ATR-based Stop Loss and Take Profit; position size calculated as a fixed percentage of account equity
• Telegram integration — Instant push notifications on trade open/close with entry price, SL, TP, P&L, and running balance
• HTML dashboard — Dark-themed performance dashboard with equity curve, open positions table, trade history, and key metrics (win rate, drawdown, avg RR)
• VPS-ready — Designed for uninterrupted 24/5 operation on a Contabo VPS (~€4/month)

Strategy Logic

Entry conditions (LONG):
  EMA9 crosses above EMA21
  AND RSI(14) > 50
  AND current session = London OR New York

Entry conditions (SHORT):
  EMA9 crosses below EMA21
  AND RSI(14) < 50
  AND current session = London OR New York

Risk management:
  SL = entry ± (ATR(14) × 1.5)
  TP = entry ± (ATR(14) × 2.5)
  Lot size = (equity × risk%) / (SL in pips × pip value)

Dashboard Preview

The dashboard reads trade history from a local CSV log and renders:

• Equity curve — cumulative P&L over time
• Open positions — live table with entry price, current price, unrealized P&L
• Trade history — paginated log with filters by pair and outcome
• KPIs — win rate, total trades, average R:R, max drawdown

Dashboard runs locally or on the same VPS as the EA.
