Algorithmic Execution & Quant Systems

A family of production trading systems — signal bridges, strategy bots, copy-trading, and portfolio rebalancing — running 24/7 with human oversight.

At a glance: Across many projects, Ethereal has built automated trading systems that place trades around the clock while a person keeps watch. They cover everything from turning chart alerts into real orders, to copying one trader's moves across several accounts, to strict safety limits that cap losses. Every strategy is tested against years of history before real money is used.

01

The Problem

Traders and desks need reliable, automated, low-latency execution and validated strategies — without manual order entry, and without trusting untested logic with real money.

Latency

Manual order entry loses the edge — by the time a human sees the chart and places the trade, the price has moved.

Risk

Multiple strategies firing at once, or one untested rule going haywire, can over-leverage an account and compound a small loss into a large one.

Overfitting

A strategy tuned to last month's noise looks brilliant in hindsight and quietly fails the moment it meets a live market.

02

The Solution

We built a family of production systems: a TradingView→MT5 signal bridge; Supertrend, RSI, stochastic, and FVG bots with trailing stops and paper-trading mode; multi-account copy-trading replication; regime-aware momentum-portfolio rebalancing; and a CPU-only forecasting engine. Every system runs on explicit state machines with full logging and operator dashboards.

The execution stack
L1Layer

Signal

Strategy and indicator engines emit signals from market data — Supertrend, RSI, stochastic, and FVG logic, validated against years of history.

L2Layer

Risk Gate

Every signal passes loss limits, position sizing, cooldowns, and a kill-switch before it is allowed to become an order.

L3Layer

Execution

A broker-agnostic router places risk-managed orders across Zerodha Kite and MetaTrader5, with trailing stops and paper mode.

L4Core

Oversight

State machines, structured logs, and live dashboards keep a human in the loop with 24/7 visibility into every position and violation.

Defense in depth

Pre-trade validation blocks bad orders before entry; live supervision catches violations that emerge after a position is open.

Human in the loop

Systems run automated and continuously, but every state and rule trigger is logged and surfaced so an operator can intervene.

The systems
Signal Bridge

A TradingView→MT5 webhook bridge translates chart alerts into passphrase-validated, risk-sized forex orders.

Indicator Bots

Supertrend, RSI, stochastic, and FVG bots trade with trailing stops and a paper mode for safe dry runs.

Copy Trading

A multi-account engine mirrors validated fills across brokers so one signal executes everywhere at once.

Momentum Rebalancing

A regime-aware portfolio engine rotates into momentum leaders and rebalances as conditions shift.

Forecasting Engine

A CPU-only, vectorized backtesting engine stress-tests thousands of parameter sets to reject overfit strategies.

Risk Supervisor

A live guardian enforces loss limits, sizing, and forced cooldowns, halting on a daily kill-switch.

03

The Outcome

Systematic 24/7 execution with human oversight — backtested, test-covered strategies running across multiple brokers and accounts.
