Callidus EA

Adaptive Multi-Strategy EA: Callidus

Callidus is not just another Expert Advisor; it is a comprehensive, institutional-grade trading framework designed for the modern markets. Built on a foundation of adaptive logic and robust risk management, Callidus automatically adjusts its strategy to changing market conditions, aiming to maximize opportunities while rigorously protecting your capital. Intelligently Reacts to Market Shifts & Filters Trades with Machine Learning.

Key Features:

• Intelligent Market Regime Detection:

• ADX-Powered Analysis: Callidus uses the Average Directional Index (ADX) to determine the current state of the market. It intelligently identifies whether the market is in a strong trend or a sideways range.
• Automatic Strategy Switching: Based on the market regime, the EA automatically deploys the most suitable strategy:
• Trending Markets: A robust EMA Crossover Engine is activated to capture momentum and ride established trends.
• Ranging Markets: A sophisticated Support/Resistance Pullback Engine is engaged, designed to identify pullbacks to key S/R levels and trade the reversal. This adaptive logic ensures the EA is always using the right tool for the job.

• Machine Learning (ML) Trade Filter:

• Go beyond simple indicators. Callidus uses a built-in, trained Logistic Regression model to calculate the probability of a trade's success before it is opened.
• Only high-probability setups are taken, filtering out weak signals and improving the overall quality of trades. The confidence threshold is fully customizable.

• Advanced Multi-Pair Trading:

• Designed from the ground up to trade multiple symbols simultaneously from a single chart.
• Efficiently manages indicators and trade logic for your entire specified portfolio (e.g., EURUSD, GBPUSD, XAUUSD).

• Sophisticated Risk Management & Trade Control:

  • Selectable Lot Sizing: Choose between a dynamic risk percentage of your account balance or a fixed lot size, giving you complete control over your position sizing.
  • Smart Basket Hedging: A revolutionary approach to managing losing trades. Instead of a high-risk Martingale, Callidus can open fixed-lot hedges and manage the entire group of trades as a "basket," closing all positions when a predefined profit or stop-loss target (in account currency) is reached. This contains risk and prevents catastrophic losses. (Classic Martingale-style recovery is also available as an option).
  • Multi-Stage Profit Taking: Secure your profits progressively with up to three partial take-profit levels based on ATR multiples.
  • Advanced Trade Management: Includes fully configurable Break-Even, ATR-based Trailing Stop, Max Holding Time, and more.

Built for Serious Traders:

• Comprehensive Filters: Protect your account with filters for maximum spread, daily drawdown, time-of-day trading, and minimum win rate.
• Performance Optimized: Features "once per bar" logic to ensure backtesting is lightning-fast and live CPU usage is minimal.
• Informative Dashboard: An optional on-chart dashboard provides a real-time overview of your account equity, open positions, and EA performance.

Why is Callidus EA Different?

• It's Powered by Machine Learning: Before any trade is opened, our built-in ML filter analyzes the setup and calculates its probability of success. Only high-probability trades are executed, keeping you out of weak setups.

• It Features Smart Basket Hedging: Forget dangerous Martingale strategies. When a trade goes against you, Callidus uses a sophisticated basket management system. It can open hedges to manage the position and aims to close the entire group of trades at a small profit or a predefined, controlled stop-loss. This is risk management, evolved.

• It's Built for Performance: Trade multiple symbols (Forex, Indices, Gold) from a single chart. With highly optimized "once per bar" logic, backtesting is fast and efficient, allowing you to find the perfect settings quickly.

• You Are in Full Control: From dynamic risk-based lot sizing to multi-stage take profits, break-even, and trailing stops, every aspect of trade management is fully customizable to fit your personal trading style.

How to Use Callidus: A Guide to Key Parameters

Callidus EA is designed to be powerful yet user-friendly. Here’s a breakdown of the most important settings to get you started.

1. General & Strategy Settings

• SymbolsList : Enter the symbols you want to trade, separated by commas (e.g., "EURUSD,XAUUSD,US30").
• TradeTF : The primary timeframe for the trading strategy (e.g., H1).
• EnableRSI  &  EnableMTFConfirm : Use these boolean switches to turn the RSI and Multi-Timeframe confirmation filters on or off.

2. Risk Management & Level Settings

• RiskPercent : The core of your risk management. The EA will automatically calculate the lot size for each trade to risk this percentage of your account balance. Set to  0  to use a fixed lot size.
• ATRStopMultiplier  &  ATRTPMultiplier : These define your risk-to-reward ratio based on the market's current volatility (ATR). For example, a setting of  2.0  for SL and  3.0  for TP sets a 1:1.5 R:R based on ATR.

3. Machine Learning Filter

This is the "brain" of the EA.

• EnableMLFilter : Turn the probability filter on or off.
• MinMLThreshold : The minimum confidence score (from 0.0 to 1.0) required for the EA to open a trade. A higher value (e.g., 0.60) makes the EA more selective, taking fewer but higher-probability trades. A value of  0.50  will take any trade the model slightly favors. This is a key parameter to optimize.

4. Hedging System: Basket vs. Martingale

You have two powerful recovery modes. It is highly recommended to use the  Basket Closure  mode for safer trading.

• To use Basket Mode (Recommended):
  • Set  UseBasketClose = true .
  • Set  EnableSmartHedge = true .
  • BasketHedgeLotSize : The fixed lot size for all hedge trades.
  • BasketProfitTarget  &  BasketStopLoss : The dollar value at which to close the entire group of trades. This contains your risk.
• To use Martingale Mode (High Risk):
  • Set  UseBasketClose = false .
  • Set  EnableSmartHedge = true .
  • HedgeMultiplier : The multiplier for lot size on each new hedge trade (e.g., 1.5x). Use with extreme caution.

5. Adaptive Strategy: Market Regime Filters This is the core of Callidus's intelligence. It automatically analyzes the market and chooses the best strategy.

• EnableADXFilter: When  true , the EA uses the ADX indicator to determine if the market is trending or ranging.
• EnableSRPullback: When  true  (and the ADX filter detects a ranging market), the EA will use the Support/Resistance Pullback strategy. If  false  or if the market is trending, it will use the default EMA Crossover strategy.

Tests and settings:

All tests were done on Every tick based on real ticks and an average of 104 ms server delay on a 10.000 USD account.

Every test result can be found as screenshots, with these exact settings.

If you change settings while testing (which I highly recommend, because you can find even better strategies), wait 1-2 minutes for the tester to load, otherwise it will only show a straight line/no trades taken. This happens because the ML filter goes back hundreds of bars every time you change something. 

If the EA trades and then flatlines in tester, try turning the winrate filter off, or modifying the drawdown percent to be higher, so it will let the EA open more positions.
