Leria

LERIA is an automated multi-currency grid trading EA for MetaTrader 5, built specifically around AUDCAD, AUDNZD, and NZDCAD (maximum 3 pairs by design). It combines a Keltner Channel range-breakout entry filter with adaptive grid spacing, a multi-stage lot multiplier system, and a correlation-aware position sizer that scales lot size based on measured correlation between open positions.

Core Principle: Adaptive Grid With Correlation Awareness

LERIA opens an initial position when price breaks beyond a Keltner Channel range with RSI confirmation. If price moves against the position, additional grid levels are added using spacing that adapts automatically to current volatility (relative to its longer-term average), with lot size scaled by level through a tiered multiplier system. Because its default pairs are inherently correlated, LERIA measures live correlation between open positions and scales the lot size on a new trade when correlation with an existing position crosses a set threshold.

Must Read:

LERIA includes built-in configurable risk controls: a daily loss limit, daily and monthly profit-lock targets, and a maximum drawdown circuit breaker that halts all trading for 24 hours once triggered. The EA also auto-detects whether your account is netting or hedging and disables incompatible settings automatically, and checks each symbol's actual broker session hours before attempting trades, so it won't retry during closed sessions or unsupported account configurations.

Notes:

Test all settings on a demo account before running on a live account. Lower lot sizes and lower margin percentages are recommended for smaller account balances. A VPS is recommended for uninterrupted operation. The EA does not guarantee profits, and past backtest results do not represent future performance. Risk management inputs should be configured according to individual account size and risk tolerance.
