Table of Contents OSA Scalper Pips EA — XAUUSD M5 Pinbar Scalper with MACD Trend Filter OSA Scalper Pips is a MetaTrader 4 Expert Advisor that scalps XAUUSD on the M5 timeframe using pinbar signals filtered by a built-in MACD-based trend confirmation layer. A 5.5-month backtest on $100 starting capital recorded a 97.06% win rate across 9,011 trades with a profit factor of 34.7. ➡️ Vender Website: View here Key Benefits ✅ Win Rate: 97% across 9,011 backtest trades on XAUUSD M5 — achieved using Control Points modeling, the crudest MT4 method, which inflates win rates by missing spread and slippage entirely. ✅ Strategy: Pinbar pattern MACD trend alignment targets short momentum bursts on Gold — the pinbar-always-true default means the EA opens trades even when no genuine signal exists, which is a documented parameter bug, not a feature. Compare EA strategies ✅ Trailing Stop: Trailing stop activates at 40 pips profit and locks at 35 pips — protects open profit on winning trades but cannot prevent cascading loss when Max_Order reaches 200 open positions simultaneously. ✅ Platform: MT4 only, single pair (XAUUSD), M5 timeframe — straightforward to deploy; no multi-pair complexity. >>>> Join the Telegram community for free discussions. OSA Scalper Pips EA Performance A 5.5-month backtest (October 2025 – March 2026) on $100 initial deposit recorded 9,011 trades, 97.06% win rate, profit factor 34.7, and absolute drawdown of approximately 10.5% of initial deposit. Oct 2025–Mar 2026 backtest — Control Points model, $100 starting deposit ⚠️ Demo account (Mar 18–20 2026) — -53.44% loss, 58.19% drawdown in 3 days Live panel — XAUUSD active, zero balance allocated, pinbar defaults on Metric Value Total Trades 9,011 Win Rate 97.06% Profit Factor 34.7 Absolute Drawdown ~10.5% of initial deposit (backtest) Starting Deposit (backtest) $100 Test Period Oct 2025 – Mar 2026 (5.5 months) Demo Account DD (3 days live) -58.19% Modeling Quality Control Points (not quantified %) The backtest used MT4’s Control Points model — the platform’s own report labels this “a very crude method; results must not be considered.” Control Points reconstructs price from OHLC data only, skipping tick-level movement entirely, which means spread, slippage, and between-bar price action are absent from every trade calculation. A profit factor of 34.7 generated under these conditions tells you the EA can find directional trades on XAUUSD M5 — it does not tell you what it will do when real spread hits every entry. The live evidence answers that question directly: a demo account running the default settings lost 53.44% of a $1,000 deposit in three trading days (March 18–20, 2026), with peak drawdown reaching 58.19%. The trigger is structural — BuyPinbarAlwaysTrueIfNoSignal: true and SellPinbarAlwaysTrueIfNoSignal: true force the EA to open positions even when its own signal logic finds nothing valid, and Max_Order: 200 allows up to 200 simultaneous open positions with a stop loss of 10,000 pips per trade. This is a Structural weakness: it cannot be removed by parameter adjustment because the forced-entry flags and uncapped position count are the default operating mode. Setting BuyPinbarAlwaysTrueIfNoSignal and SellPinbarAlwaysTrueIfNoSignal to false and reducing Max_Order to a single-digit value are the minimum required changes before any forward testing. The post-mitigation outcome at those settings is not documented — demo testing is required to classify what, if any, viable performance remains. A 3-day demo run confirms the default configuration loses capital rapidly; it cannot confirm whether modified settings produce stable results under live spread and execution conditions. How OSA Scalper Pips Works Mechanism: The EA targets pinbar candlestick reversals on XAUUSD M5, using a built-in OSA_fTrend filter on M1 to confirm directional bias before entry. The intended edge is short-term momentum exhaustion on Gold — a liquid instrument where pinbar patterns carry some statistical validity. The flaw in default configuration is that BuyPinbarAlwaysTrueIfNoSignal and SellPinbarAlwaysTrueIfNoSignal are both true, so the trend filter’s output is bypassed and positions open regardless of signal quality. Signal Trigger: Pinbar detection on M5 confirmed by M1 OSA_fTrend filter (HalfLength 12, Close price). MACD (8/13/5, Close) provides additional directional context. Default settings disable all three time filters, so the EA trades around the clock. Position Close: Take profit fixed at 100 pips. Trailing stop activates at 40 pips profit and locks in 35 pips. Close_BySignal is set to false — signal reversal does not trigger an early exit. Exposure Limits: Max_Order is set to 200 by default — functionally unlimited for retail account sizes. Stop loss per trade is 10,000 pips, which provides no meaningful protection. LotMultiply at 1.0 keeps position sizing flat across the basket rather than scaling exponentially, but 200 simultaneous 0.01-lot positions on XAUUSD still represent significant margin exposure. ✅ Optimal conditions: Trending XAUUSD sessions with clear directional momentum on M1/M5; low-spread ECN execution below 5 pips; modified settings with forced-entry flags disabled and Max_Order capped at 3–5. ⚠️ Avoid when: Running default configuration on any live or demo account with real capital; during high-impact news events where Gold spread widens sharply and the uncapped position count compounds exposure rapidly.

Frequently Asked Questions What results can I realistically expect with OSA Scalper Pips EA? Default settings produced a 53% account loss in three days on a $1,000 demo account — that is the documented starting point. Modified settings with forced-entry flags disabled and Max_Order capped have not been tested and documented. Your actual results depend on how aggressively you adjust these parameters and how many demo days you run before going live. Do not deploy capital without at minimum 60 days of forward-tested, modified-configuration demo data.Is OSA Scalper Pips EA safe to use on a live account? Not in default configuration. BuyPinbarAlwaysTrueIfNoSignal and SellPinbarAlwaysTrueIfNoSignal are both true by default, meaning the EA opens trades even when its own signal logic finds nothing valid. Combined with Max_Order 200 and a 10,000-pip stop loss, this produced 58.19% drawdown in three days on demo. Set both pinbar flags to false and cap Max_Order at 3–5 before any forward testing.What trading strategy does OSA Scalper Pips EA use? The EA identifies pinbar reversal patterns on XAUUSD M5 and confirms direction using a built-in M1 trend filter alongside MACD (8/13/5). In theory, it only enters when both signal and trend align. In default configuration, the pinbar-always-true flags override that filter entirely, removing the confirmation logic the strategy is built around.Does OSA Scalper Pips EA work on Gold (XAUUSD)? Yes — XAUUSD M5 is the only documented pair and timeframe. The backtest covers October 2025 to March 2026 on XAUUSD exclusively. The strategy's pinbar logic and MACD settings are calibrated for Gold's volatility profile and have not been tested on other instruments.How much capital do I need to get started with OSA Scalper Pips EA? The backtest ran on $100, but the demo account used $1,000 and lost 53% in three days under default settings. A minimum of $1,000 on a demo account is required for meaningful forward testing with modified parameters. Undercapitalization is not the primary risk here — the default configuration's uncapped position count is. Resolve parameter settings before determining final capital allocation.What are the main risks and how does OSA Scalper Pips EA handle them? The core risk is forced-entry behavior: when BuyPinbarAlwaysTrueIfNoSignal and SellPinbarAlwaysTrueIfNoSignal are true, the EA opens positions continuously regardless of signal quality, stacking up to 200 trades simultaneously against a 10,000-pip stop loss that provides no practical protection. This creates compounding exposure across a full Gold session that margin cannot absorb. The EA's trailing stop (activating at 40 pips) addresses profit protection on winning trades but cannot offset the mass of unclosed losing positions that accumulate under default settings. Disabling the forced-entry flags and capping Max_Order are the two controls that address this mechanically — those are the settings the EA actually activates to limit position accumulation.Which brokers and account types work best with OSA Scalper Pips EA? ECN brokers with tight XAUUSD spreads are required — the M5 scalper targets small pip movements where spread directly eats into the 100-pip take profit target. Spread above 5 pips on Gold significantly degrades entry quality. The demo data used Tickmill at 1:500 leverage. Avoid market-maker brokers where Gold spreads widen unpredictably during London and New York session overlaps, as the EA has no spread filter active in default configuration (MaxSpreadPips: 0).What support do I get after purchasing?
