Should You Turn Off Your EA on Weekends and Big News? A Decision Table
Weekend gaps and big news like NFP/FOMC blow spreads up several-fold and make slippage wild. Whether to pause depends on your EA's strategy — here's a decision table by type, plus the practical settings.
"Should I turn my EA off for big news and weekends?" — it's the most common ops dilemma once you're live. The answer isn't a flat "yes" or "no"; it depends on your EA's strategy type. First understand why these two windows are dangerous, then match your case.
Why these windows are dangerous
Big news (NFP, the Fed's FOMC, CPI and the like): liquidity dries up at the release, the spread blows from a few points to dozens, quotes gap, and stop orders fill at the worst price (slippage). For strategies that depend on a tight spread, one release can eat dozens of trades' worth of profit.
Weekends: FX is closed for ~48 hours from Friday to Monday; anything that breaks in between (geopolitics, an emergency central-bank move) gaps straight into Monday's open — your stop can be skipped and fill far worse. Holding over the weekend also costs swap, usually triple on Wednesdays.
A decision table by strategy
There's no one-size answer — find your EA's type:
- Scalping / high-frequency (especially gold scalpers): turn it off around news. These make thin profit inside a tight spread; once it widens the edge is gone and slippage chops you repeatedly (how spread cost eats profit: here).
- Grid / martingale: news and weekend gaps are its number-one killer. A one-way move plus a gap stacks the averaging chain at the worst spot — the classic grid blow-up (why: grid & martingale risk). Trim or pause before major news, and avoid heavy positions over the weekend.
- Trend / swing: relatively tolerant. Some trend systems actually want the post-news move — but only if you accept entry slippage and keep size light. You can let it run, just lower leverage and lot size.
- Intraday, close-before-EOD types: they don't hold overnight or over weekends, so the weekend problem is avoided by design; just mind entries around news.
How to make it dodge automatically
- Use the EA's built-in news filter: many EAs have a NewsFilter input that pauses N minutes around high-impact data. Turn it on and set the impact level for your symbol.
- Watch the economic calendar: each Monday, scan the week's high-impact events (your broker platform usually has one) so nothing surprises you.
- Friday close routine: for scalpers/grids, close or cut floating positions into Friday's close; for trend systems, judge whether the gap is worth holding.
- Keep the VPS online: whether "auto-pause" or "manual close," the EA must actually be running at that moment — a home PC that drops offline or sleeps can't act, which is exactly why you run a VPS.
A counter-intuitive point: over-intervening costs too
Some traders, out of fear, switch the EA off so often they miss the moves the strategy was built to catch — live ends up far below the backtest. The rule for turning it off should be written down, not based on mood: which impact level, for how long, hold over weekends or not — decide in advance and let it execute mechanically. A good habit is to test "news filter on" vs "off" on history first and see which curve is better (how to backtest: here).
Don't want to babysit these ops details? Managed accounts handle news and weekends for you by risk tier; prefer to pick a strategy-clear, risk-transparent EA yourself? Start from the store (use WELCOME10 for 10% off) — each one labels its strategy type and live signal.
Risk note: this is an operations explainer, not investment advice. EAs / algo trading are high risk; news and gaps can cause slippage and losses beyond expectations; past performance doesn't represent future returns. Only trade with money you can afford to lose.
