What Is Parasite EA and How Does It Work?

Parasite EA an automated trading program, also known as an Expert Advisor (EA), designed for MetaTrader platforms. The name “Parasite” hints at its core concept: the software tries to “attach” itself to the trading behavior of large banks and institutions, following their high-volume buy and sell orders as closely as possible.

Unlike many retail robots that rely on grid or martingale methods, Parasite EA applies artificial intelligence to:

• Detect sudden spikes in trading volume.
• Measure the ratio between aggressive buyers and sellers.
• Place trades with a fixed 30-pip stop loss while allowing a floating take-profit target.

By working this way, the EA keeps risk limited yet seeks to capture strong momentum once heavy orders hit the market.

Why the Trading Community Calls It the “HiJack” Expert Advisor

The software has circulated privately for several years under the nickname “HiJack” because it effectively hijacks institutional flow. After many internal tests, the developers agreed to make it public so individual traders can benefit from its approach.

HiJack—also referred to as Parasite EA—uses:

• AI-driven pattern recognition.
• Real-time order-book analysis (from liquidity-provider feeds).
• A fast order-execution engine coded in C++.

These tools help it cut latency and jump in ahead of slower retail orders. All trading decisions remain fully transparent in the parameters menu, so you can adjust risk in line with your account size.

Money Management and Lot Sizing Explained

Parasite EA offers both fixed and dynamic position sizing so it can scale from small to large accounts.

Parameter overview:

• LotsPer1000 – Main risk factor. If set to 0.1, the EA opens 0.01 lots per $100 of free margin (0.1 × 1/10).
• MinLots – Minimum trade size the EA will ever place.
• MaxLots – Hard ceiling, useful for limiting size on high-leverage accounts.
• LotsSize – Use this only if you want one fixed lot size for every trade. Setting this above 0 disables LotsPer1000.

Example: You have $500 equity, 1:200 leverage, LotsPer1000 = 0.2.Formula → 0.2 × (500/1000) = 0.1 lot. This stays well within typical risk limits.

Tip: Keep your risk per trade below 2% of balance. With a 30-pip stop on XAUUSD, 0.1 lot equals roughly $30 risk on Gold (value per pip ≈ $1).

Risk Controls Every User Should Check

The EA is already conservative, but you can tighten rules further.

• def_SL – Remains fixed at 30 pips by default.
• Distance_trailing – Gap between price and trailing stop. 25 pips is a good start.
• Start_trailing – Profit level to activate the trailing stop, e.g., 20 pips.
• EnableRiskFree – True makes the stop loss move to break-even once RiskFreePips are reached.
• RiskFreePips – Usually 15–20 pips on Gold; 10–12 on EURUSD.

Spread & Slippage filters:

• def_MaxSpread – Set 30 (points) for Gold, 25 for EURUSD.
• MaxAllowedStopLevel – Leave at 0 if your broker has no hard stop-level rule.
• Slippage – 3 to 5 points keeps fills realistic without too many re-quotes.

Trading Filters and Market Conditions

The Moving Average (MA) filter stops the EA from trading against the trend.

• EnableMAFilter – True by default.
• MAPeriod – 200 bars on the 1-minute chart captures broader direction.
• MATimeframe – Current by default. If you wish to filter by higher timeframes, set this to H1 or H4.
• MAMethod – EMA is smoother than SMA for fast markets like Gold.
• MAPrice – Close price is standard.

A quick way to check the filter:

If price > MA and institutional orders show buys → EA buys.
If price < MA and institutional orders show sells → EA sells.

Daily Limits and How to Avoid Over-Trading

Stop trading once your daily profit or trade count hits a safe threshold.

• MaxDailyTrades – Helps prevent revenge trading during choppy sessions. A setting of 5 trades is common for M1 Gold.
• DailyProfitLimit – Once the EA closes enough trades to reach this dollar amount, it suspends itself until the next day.
• StartHour / EndHour – Define your trading window. For example, many Gold traders stick to 08:00–18:00 broker time to avoid low liquidity.

Pro tip: Combine DailyProfitLimit with the broker’s server time. If your broker’s end-of-day is midnight GMT+2, you can finish the trading day before rollover fees hit.
