The search for a reliable automated trading solution often leads traders to the doorstep of scalping robots. Among the crowded marketplace of MetaTrader 5 tools, the RoyalPrince Scalper EA V1.50 MT5 stands out as a specialized breakout system. Developed by Richard Louis Pastor, this expert advisor is engineered to navigate the fast-paced world of scalping by focusing on price action rather than lagging indicators. In this technical deep dive, we explore why this version is considered the professional upgrade of the RoyalPrince series and how it handles the modern forex market.


The RoyalPrince Scalper EA V1.50 is built on the philosophy of high-probability breakout trading. Unlike many retail bots that attempt to predict market direction using over-optimized oscillators, this EA waits for the market to define its boundaries. It specifically targets the high and low points of a set time period, typically the one-hour candle, to establish its entry zones. By placing pending buy stop and sell stop orders at these critical levels, the robot ensures that it only enters a position when there is sufficient momentum to push the price through a technical ceiling or floor.


One of the most significant advantages of the V1.50 edition is its departure from high-risk recovery methods. The forex community is well aware of the dangers posed by Martingale and Grid strategies, which can double down on losing positions and lead to catastrophic account drawdowns. The RoyalPrince Scalper V1.50 employs a fixed lot or percentage-based risk model. Every single trade is protected by a hard stop loss, ensuring that no single market anomaly can wipe out a trader's capital. This conservative approach makes it a viable candidate for those looking to preserve their balance while seeking incremental growth.



The technical architecture of the V1.50 version introduces several sophisticated filters that were missing in earlier iterations. The integrated news filter is perhaps the most vital. High-impact economic data releases can cause massive slippage and unpredictable price gaps that are detrimental to scalping strategies. This EA allows users to pause trading during these volatile windows, protecting the strategy from the "noise" of fundamental events. Furthermore, the inclusion of equity and margin protection settings adds another layer of security, allowing the software to automatically halt trading if the account reaches a pre-defined risk threshold.


Optimized primarily for the USDJPY currency pair, the RoyalPrince Scalper EA V1.50 performs best on the M15 timeframe for execution while drawing its logic from the H1 chart. The developer has refined the settings to capitalize on the unique volatility characteristics of the Yen pairs. However, for the robot to operate at peak efficiency, the trading environment is just as important as the code itself. Because scalping relies on capturing small price movements of 5 to 10 pips, the spread offered by the broker becomes a make-or-break factor. Traders using this EA are encouraged to utilize ECN accounts with raw spreads and low commissions. High-latency connections are the enemy of this bot, making the use of a Virtual Private Server located near the broker's data center a necessity rather than an option.



While the backtesting data provided by the developer shows a promising upward trajectory, real-world application requires a nuanced understanding of market conditions. User reports indicate that while the bot can find stability and consistent small wins in trending markets, it may struggle during prolonged periods of consolidation where "fakeouts" occur. A fakeout happens when the price triggers a breakout level but lacks the follow-through momentum, resulting in a small loss. The adjustable trailing stop in version 1.50 is designed to mitigate this by moving the stop loss to breakeven as quickly as possible, though this requires a broker with minimal slippage.


Recent developments in the MQL5 marketplace regarding the developer's status have raised questions about future updates. It is important for users to note that the author has faced restrictions on the official platform, which means that direct support may be limited. For traders who already possess the software, the focus should remain on rigorous optimization. No expert advisor is truly "plug and play." Regular optimization of the trailing stop distance and the breakout offset is required to keep pace with changing market volatility.


In conclusion, the RoyalPrince Scalper EA V1.50 MT5 represents a professional attempt at automating a classic breakout strategy. Its strengths lie in its disciplined risk management and its avoidance of dangerous betting patterns. It serves as a reminder that in the world of algorithmic trading, simplicity and protection are often more valuable than complex, high-risk logic. For those with the technical infrastructure to support high-speed scalping, this EA offers a structured framework to engage with the forex market.
