Au 79

Au 79 is an expert advisor for MetaTrader 5 that trades gold (XAUUSD). Instead of relying on one entry method, it runs five separate strategies on the same chart, pairing short-term scalping with slower breakout logic so that each can operate when the other is quiet.

How it works

The five engines work on different time horizons but share one internal mechanism for hedging and distributing risk. Long and short exposure can be armed around the same price structure at the same time. When price moves, the side that is working is allowed to run, while the opposite side is closed by its own protective stop or retired automatically. The aim is to spread risk across engines rather than rely on a single entry.

Order handling

• Every trade carries a stop loss and a take profit from the moment it is opened.
• A distance filter stops the engines from placing orders on top of one another.
• There is no martingale, no grid and no adding to losing positions.
• Decisions come from fixed price-structure rules, not from a learning model, so you can follow what it does in the terminal journal.

Markets and timeframes

The EA is designed for XAUUSD only. It can be attached to any timeframe, and H1 is the suggested chart. Attach it to one chart only; the engines inside handle the rest. The scalping engine reacts to spread, so a raw or ECN account with low spreads is preferred. If your account has wide spreads, reduce its activity or switch that part off and let the breakout engines work alone.

Risk module

A built-in protection layer is aimed at traders who need to stay within account limits.

• Daily drawdown limit, set as a percentage or a fixed amount and measured from equity at server midnight.
• Total drawdown limit, measured from the initial deposit and independent of the daily rule.
• Both rules trigger at a fraction of the limit, 90 percent by default, so closing fills and spread are less likely to cross the real line.
• Baseline values and breach state are kept in terminal global variables, so a recompile, timeframe change or restart does not reset the counter.
• A timer-based check keeps running when the price feed stalls.
• Optional randomised offsets on entries, stops, targets and trailing.

Settings

Most strategy internals are pre-set, so the input list is short. Exact input names and defaults can differ between releases, so read the inputs tab after attaching the EA and check the product page.
