Key Features & Claimed Functionality

Here are its commonly advertised features:

Feature	What It Does/Claims
Low-Risk Approach	Does not use martingale, grids, or other high-drawdown recovery systems

Adaptive Risk / Lot Size Control	Lot sizing can be fixed or risk-percentage based; risk per trade is controlled.
Entry Filters / Signal Logic	Uses various filters such as: spread filters (skip trades when spread is too large), trend bias (higher timeframe trend), possibly price action confirmation (candlestick patterns), volatility filters.
Timeframe / Pairs	Optimized for major, low-spread forex pairs (e.g. EUR/USD, GBP/USD, USD/JPY). Timeframes typically short (M1–M15) for scalping.
Avoids High Volatility Events	Includes filters to avoid trading during news or sessions known for wide spreads or low liquidity. Possibly also uses spread/slippage filters to avoid bad entries.
Customizable Settings	Users can adjust things like trading hours, risk per trade, lot sizes, spread tolerance, magic number, etc.
Trade Management	Some versions come with trailing stops, maybe dynamic exit logic (locking in profit, closing early if conditions worsen).

Performance Claims & Expectations

Some backtests / vendor claims suggest small but steady returns, rather than aggressive growth.
Typical drawdowns claimed are modest (often < 5-10%) for many versions in ideal conditions.
Win rate in vendor claims often fairly high, especially because scalping profits are small and the system avoids big losses.

Putting the advertised features together, this is a reasonable guess at how Safe Scalping EA operates internally:

Monitor spread and market conditions → refuse to take a trade if spread or slippage is too high.
Check for trend (on higher timeframe) to bias direction (e.g. only take long if trend is up).
Use short-term timeframe (M1 or M5) to detect entry signals (price action, small momentum spike, breakout from small range, etc.).
Enter trade with fixed lot size or risk-based lot.
Set stop loss & take profit immediately; possibly use trailing stop or move stop to breakeven if price moves favorably.
Avoid trading during news or during known volatile periods (or spread spikes).
Possibly shut down or reduce risk outside main trading times (e.g. London/New York session).

According to vendor descriptions, Safe Scalping EA MT5 typically does not include:

Martingale or grid strategies.
Aggressive lot escalation.
Long holding trades or swing trades (it’s scalping, so trades are short duration).
Over-complex strategies; the emphasis is on simplicity and risk control.

Lower risk compared to many aggressive scalpers or recovery-based EAs.
Better suited for conservative traders who prefer stability.
Possibly good fit for funded/proprietary account challenges, where drawdown and risk control are important.
Customization allows tweaking to suit the broker / account situation.

Even with those safety features, there are still risk points:

Broker-dependence: performance will vary heavily with broker’s spread, execution delays, slippage. A scalper must have good execution.
Market regimes: scalping works well in certain periods (steady volatility, trending, or with small momentum bursts), but poorly in choppy or low-liquidity times.
Overfitting: vendor backtests may be optimistic; real market conditions (requotes, slippage, downtime, spikes) reduce performance.
Frequent small trades mean that costs (spreads, commissions) eat into profit; if cost is high, net profit might be thin.
Some versions might include DLLs or dependencies, which can cause compatibility issues or risk (vendor trust matters).
Requires monitoring or periodic adjustment (for example, updating spread thresholds or trading hours based on broker behavior)
