🌀 Cascada — Local-First Copy Trading Desktop App

🌊 What Is Cascada?

Imagine a trading companion that never phones home, never asks for a subscription, and never exposes your strategy to the cloud. Cascada is a local-first, zero-commission copy-trading desktop application purpose-built for cTrader, MetaTrader 4, and MetaTrader 5.

Built with Tauri 2, Rust, and Svelte, Cascada operates entirely offline-by-design — your signals, your trades, your sovereign control. No hidden servers, no data leakage, no monthly fees. It’s copy trading the way it should have always been: yours.

🧭 Philosophy: Your Trades, Your Territory

Most copy-trading platforms are walled gardens — they own your data, throttle your execution, and charge rent for the privilege. Cascada flips that model.

Think of it as a private lighthouse on a remote island: your signals beam locally, your trades execute directly through the brokerage APIs you trust, and the entire infrastructure lives on your machine. No cloud dependency, no third-party middleman, no surveillance.

"Copy trading is not a service — it's a lens. Cascada lets you build your own lens."

No external servers are contacted. All signal handling, trade replication, and risk logic runs locally within the Rust core.

📋 OS Compatibility

All builds are offline-first — no telemetry, no update pinging, no license validation.

🎛️ Example Profile Configuration

Below is a sample cascada_profile.toml that defines a moderate copy-trading strategy targeting both MetaTrader 5 and cTrader simultaneously.

[profile]
name = "moderate-arb"
version = "2026.1"
description = "Semi-automated copy trading with slippage tolerance"

[risk]
max_position_size_percent = 5.0
daily_loss_limit_percent = 8.0
max_concurrent_trades = 3
slippage_tolerance_pips = 1.5

[replication]
copy_signals_from = ["mt5:1245678", "ctrader:9876543"]
delay_before_entry_ms = 200
inverse_relationship = false

[execution]
platforms = ["mt5", "ctrader", "mt4"]
use_market_orders = true
retry_count = 2
retry_interval_ms = 500

[logging]
log_level = "info"
log_to_file = true
log_rotation_days = 14

🖥️ Example Console Invocation

Once installed, run Cascada directly from the terminal:

cascada --profile moderate-arb --account mt5:1245678 --offline

This launches the Tauri desktop window with the predefined profile and immediately connects to the local MT5 account without any cloud handshake.

For headless operation (advanced):

cascada --headless --profile aggressive --log stdout

This runs the Rust core in CLI mode, printing replication logs directly to the terminal — ideal for servers or automated setups.

🔌 API Integration

Cascada is designed to consume but never expose — it integrates with third-party APIs locally without sending data outward.

OpenAI API Integration (Optional)

• Use GPT-4o or o3-mini to analyze historical signal patterns locally via a local proxy that never sends raw account data.
• Generate natural-language summaries of replication performance without uploading trade history.

Claude API Integration (Optional)

• Employ Claude 3.5 Sonnet or Claude Opus to parse unstructured trading notes or chat logs and convert them into signal rules.
• All API calls are routed through a local proxy that anonymizes your account identifiers.

Both integrations are opt-in and fully configurable via environment variables. No data is ever cached or sent to third parties beyond the API call itself.

⚠️ Disclaimer

Trading financial instruments involves substantial risk of loss. Cascada is a non-custodial, local-first tool that merely replicates trading signals based on your configuration.

• The developers of Cascada do not provide financial advice.
• Past performance of any copied strategy does not guarantee future results.
• You are solely responsible for your trading decisions and any losses incurred.
• Cascada does not execute trades on your behalf autonomously — it replicates only what you configure.
• Always test any new configuration in a demo account before applying to live funds.

Cascada is a tool, not an advisor. Trade with capital you can afford to lose.
