A Daily EURUSD Expert Advisor Using Prior-Day Extremes and Patterns

Summary

Andrea Zani describes AZXY, an Expert Advisor built for the 2011 Automated Trading Championship. It uses the previous day’s minimum and maximum prices, together with patterns compared against prior-year patterns, to choose a buy or sell direction. The system places one order per day and waits for a preset profit target, closing any remaining position at 10 p.m. It does not follow trends and has no stop-loss level. Zani says it used the maximum possible lot size and split large orders because of problems handling orders above three lots during preliminary testing.

The interview offers a concrete account of development and operation rather than a validated strategy study. Zani reports a competition ranking he considered good at the time, but also says a losing trade caused a 50% deposit loss when a stop-out rule closed the position. The EA was made for the contest, not used for live trading, and its daily pattern method and profit potential are not independently tested here. The example highlights how position sizing, order handling, and the absence of a stop-loss can dominate outcomes even when entry logic appears simple.

Key ideas

• The EA uses previous-day price extremes and historical patterns to choose a daily buy or sell order.
• It waits for a preset profit target and closes any open position at 10 p.m.
• The system has no stop-loss and used maximum lot sizing, exposing it to substantial losses.
• The interview reports contest experience, not independently verified live-trading performance.
