Custom MT5 Indicator High winrate

I am looking for an experienced MQL5 developer to create a custom indicator (not an EA, no auto-trading) for MetaTrader 5 with the following exact requirements:

1. Analysis & Signal Generation

• Use Moving Average crossover (configurable fast/slow MA, e.g., EMA 9/21 or 50/200) as the main signal trigger.
• Add RSI filter (period 14, configurable levels, e.g., Buy when RSI > 50 or < 30 for oversold confirmation, Sell opposite).
• Generate signal only when both MA crossover and RSI condition are aligned.
• Optional multi-timeframe confirmation (e.g., M15 signal must match H1 trend).
• Works on any symbol, optimized for XAUUSD.

2. On-Chart Visualization

• Draw Buy/Sell arrows when a signal triggers.
• Draw horizontal lines for SL and TP1/TP2/TP3:
  • SL in pips (input SL_pips, e.g. default 50 pips).
  • TP1/TP2/TP3 in pips (inputs TP1_pips, TP2_pips, TP3_pips, e.g. 100/200/350) or optional ATR(14) multiplier converted to pips.
• Show labels on lines: price level, pips distance, RR ratio, suggested partial close (e.g. close 40% at TP1, 30% at TP2).

3. Telegram Integration

• Send real-time alert when a new signal appears (only once per signal).
• Support emojis, new lines (\n), and parse_mode=MarkdownV2 (or HTML) for formatting (bold/italic if needed).
• Use separate emojis for Buy/Sell: 🟢 for Buy, 🔴 for Sell.
• Exact message format (with historical signal winrate right after the signal title):

• If not enough historical matches (e.g. less than 10), show “Winrate: Calculating...” or “Winrate: N/A”.
• Optional advanced feature (preferred if developer has experience): Send chart snapshot as photo via sendPhoto API (using ChartScreenShot function), with the above format as caption.
• Inputs: Bot Token, Chat ID, enable/disable winrate in message, parse_mode selection (MarkdownV2/HTML/None).

4. Historical Signal Winrate Calculation

• When a new signal is generated, save its timestamp, type (Buy/Sell), suggested entry price, and symbol (using simple CSV file or internal storage).
• Scan closed trades from history (using HistorySelect and HistoryDealGetTicket) and match to previous signals:
  • Match if open time is close to signal time (± a few minutes), same symbol, same direction.
• Win/Loss rule:
  • WIN if the matched closed trade has profit > 0 (i.e. hit at least TP1 or any profit, including partial closes or trailing).
  • LOSS if profit ≤ 0 (hit SL or loss).
• Winrate = (number of WIN matches / total matches) × 100%.
• This winrate is displayed in the Telegram message and on the chart dashboard.

5. On-Chart Dashboard

• Display a movable panel showing:
  • Daily/Weekly/Monthly summary: total pips profit/loss, number of trades, winrate %, profit factor.
  • Signal winrate: “Signal Winrate: XX% (based on Y historical matches – win if TP1+ hit)”.
• Update in real-time when new trades close or on timer.
• Inputs: enable/disable dashboard, position on chart, symbol filter (XAUUSD only or all).

6. Profitability Requirement

• Logic must be conservative and non-repainting.
• Developer must optimize in MT5 Strategy Tester (genetic algorithm preferred) using 3–5 years of high-quality tick data.
• Target metrics: Profit Factor > 1.5, Max Drawdown < 20–25%, Win Rate > 55%, steadily rising equity curve.
• Provide full backtest report (.htm or screenshots) and optimized parameter set.

General Requirements

• Full source code (.mq5) – no compiled files only.
• All key settings available as inputs (SL/TP pips, MA/RSI periods, Telegram, dashboard, min matches for winrate, etc.).
• Add MT5 popup/sound alerts as fallback.
• Compatible with latest MT5 builds.

Budget & Milestones

• Milestones:
  1. Core signal logic + SL/TP in pips + chart display (demo version).
  2. Telegram integration with formatted message (including winrate, emojis, bold, optional photo).
  3. Dashboard with summaries + historical signal winrate calculation + optimization + final polish.

Please share your portfolio with similar indicators (especially those that calculate winrate from historical trade matches, include it in Telegram alerts, and support formatted messages with emojis/bold).
