The episode identifies critical programming oversights that cause automated trading systems to gradually fail in live markets despite appearing successful in backtests. It emphasizes that performance decay often stems from subtle coding errors, such as relying on incomplete price bars or over-optimizing parameters to fit historical noise. The source also highlights the necessity of accounting for real-world execution factors like slippage, spreads, and shifting market regimes. By maintaining a clear separation between risk and signal logic, developers can prevent unpredictable behavior during strategy updates. Ultimately, the text argues that long-term profitability depends more on eliminating silent technical flaws than on the complexity of the underlying strategy. Maintaining a robust feedback loop is essential for detecting these invisible issues before they deplete a trading account.

Why do most Expert Advisors (EAs) eventually fail? According to the experts at 1kPips, it’s rarely because the strategy itself is bad—it’s because the code becomes a "fragile mess" that is impossible to maintain. In this episode, we dive deep into the MQL5 Survival Guide, exploring how to transition from writing "disposable scripts" to building long-term trading assets.

Whether you are a solo developer or managing a trading desk, this episode provides a practical framework for writing clean, maintainable code in an environment where market behaviors change constantly and bugs cost real money.

What You’ll Learn in This Episode:

• The Survival Mindset: Why clean code isn't about "academic purity," but about staying in the game long enough to win.• The Power of Separation: Why you must stop mixing indicator calculations with risk logic and how to give every block of code a single responsibility.

• Readability vs. Cleverness: Why "shorter" code is often a trap, and how descriptive variables act as built-in documentation for your future self.

• Killing Magic Numbers: The simple habit that prevents your EA from becoming a confusing puzzle of hardcoded values.

• The OnTick() Controller: How to structure your main function so it reads like English and never exceeds 70 lines

.• Refactoring for Success: A practical checklist to clean up your existing messy EAs, from removing dead code to extracting logic into reusable functions.

Key Quote:

"Treat your EA like a disposable script, and it will behave like one. Treat it like a long-term asset, and clean MQL5 code becomes a competitive advantage.

"Who This Episode Is For:

• Algorithmic traders who have abandoned profitable EAs because the code became too complex to touch.

• MQL5 developers looking to speed up their testing cycles and perform safer optimizations.

• Professional developers who want to improve their "execution quality" through better software architecture.

Every trader hunts for the "perfect" entry, a cleaner indicator, or a smarter signal, but real-world data reveals a different truth: position sizing is the engine that determines whether your account survives or explodes.

In this episode, we dive deep into why position sizing is the most critical component of forex trading, especially for those using Expert Advisors (EAs) and automated systems.

What You’ll Learn in This Episode:

• The Fatal Flaw of Fixed Lot Sizing: Why thinking in "lots" instead of "risk" leads to random and potentially catastrophic results as your account balance fluctuates.

• Risk Control in Disguise: Understanding how lot size directly controls your loss size, drawdown, and ultimate survival in the markets.

• The Only Formula That Actually Matters: We break down the essential calculation—Lot Size = (Account Balance × Risk %) ÷ Stop Loss—and explain how it keeps your risk consistent regardless of your trading style.

• The Power of Small Numbers: A look at the math behind why 1% risk keeps you in the game while 5% risk can destroy your confidence and margin after just a few losses.

• Strategy-Specific Sizing: How to adapt your trade size for different approaches, from high-frequency scalping to wide-stop swing trading.

• Common Pitfalls for EA Traders: Why systems like Martingale, unlimited grids, and ignoring correlated pairs are "boring" mistakes that fail eventually.

Key Takeaway: While entries and indicators feel "smart," they only offer marginal improvements. Mastering your position sizing offers improvements by orders of magnitude, turning average strategies into profitable ones and ensuring long-term survivability. Remember: Your lot size decides your future more than your signal.

Whether you are a manual trader or an EA enthusiast, this episode will help you stop focusing on the "perfect entry" and start focusing on the math that keeps you in the game.
