Strategy Customization Cross-platform execution without relying on EA
Based on MT4/MT5 Client API, account data, order data, quote data, and risk-control rules, we customize cross-platform trading strategies, copy-trading strategies, risk-control strategies, and automated execution logic without relying on MT4/MT5 EA plugins.
Instead of writing an EA, we turn trading rules into API-driven software modules or services that can connect to copy-trading software, website backends, risk-control systems, and data interfaces.
Rule Library
Turn manual trading rules into API services
The focus is to split business rules into verifiable, traceable, and runnable execution modules instead of depending on an EA file inside a terminal.
Signal filtering: filter by account, symbol, time, order type, floating profit/loss, and risk conditions.
Lot calculation: fixed lots, balance ratio, equity ratio, tiered lots, loss-based copying, and multipliers.
Risk-control closeout: equity protection, margin protection, loss thresholds, forced closeout, and no-copy rules.
Batch execution: batch closeout, batch order repair, batch password changes, mobile notifications, and backend linkage.
Symbol mapping: map and convert symbols across platforms, brokers, and suffixes.
Martingale grid: high-frequency position adding, closing, risk boundaries, and batch order-processing rules.
Reporting statistics: customize by yearly reports, daily reports, symbols, accounts, and customer business metrics.
System linkage: connect CRM, membership systems, website backends, data dashboards, and risk-control systems.
