Myths and Realities of Modern Trading: The 10 False Beliefs and the Technical Review of Platforms, Brokers, and Automation


Definitive Article Structure

1. Introduction: The Trading Ecosystem and Its Collective Fantasies

  • Hook: Start by stating that the trading world is saturated with false information and irrational expectations.

  • Thesis: Most traders lose not because of the market, but because of wrong decisions based on myths about their tools, brokers, and systems.

  • Promise: "Today, we are going to scrutinize the urban legends against the technical truths. Get ready for the brutal honesty that will make you evolve as a trader."



2. Section I: Myths of Platforms and Performance (MT4, MT5, and Others)

Myth (The False Belief) Reality (The Hidden Truth)
Myth #1: The perfect platform exists, and if I use it, I will profit more. REALITY: The platform is just the hammer. Profitability depends on your process, strategy, and risk management. A tool does not compensate for poor discipline.
Myth #2: MT5 is strictly better than MT4 in everything; the old version is obsolete. REALITY: MT5 is superior for multi-asset trading (futures/stocks) and advanced analysis. MT4 remains stable and a leader in algorithmic Forex trading. The choice depends on your asset and your code.
Myth #3: A platform with more indicators and drawing tools is more professional. REALITY: Technical saturation leads to "analysis paralysis." A professional platform is distinguished by its stability, execution speed, and reliability, not by the number of pre-installed tools.


3. Section II: Broker and Execution Myths (The Uncomfortable Reality)

Myth (The False Belief) Reality (The Hidden Truth)
Myth #4: The broker with $0$ spreads or a $100\%$ bonus is the miracle worker. REALITY: All brokers must make money. If it's not through the spread, it's through hidden commissions, high swaps, or by acting as the counterparty to your trade. The total cost is what matters.
Myth #5: All platforms offered by the same broker execute orders identically. REALITY (The Myth That Will Surprise You): False. Server technology, liquidity routing, and even the platform version can significantly affect execution speed and spreads, even for the same broker and the same account. A scalper or high-frequency trader must test this thoroughly.


4. Section III: MQL5 and Algorithmic Trading Myths (Self-Deception)

Myth (The False Belief) Reality (The Hidden Truth)
Myth #6: A profitable EA never loses (it requires no human intervention). REALITY: Every system, no matter how robust, enters a drawdown. Human intervention (disabling the bot during losses, changing parameters due to FOMO) destroys more systems than the market itself.
Myth #7: If I use perfect tick data, my backtest is the absolute truth. REALITY: Backtesting is an optimistic simulation. Real execution (latency, slippage, dynamic spread fluctuations) is a variable that no backtest can perfectly replicate in $100\%$ of cases.
Myth #8: More complex code in MQL5 is always more profitable. REALITY: The simplicity and robustness of the logic (strategy and risk management) outweigh the complexity of the code. A well-conceived $50$-line EA is more valuable than a monster of a thousand lines that makes no sense.
Myth #9: If I learn MQL5, I can code for any other platform. REALITY: MQL is a specific environment. You gain invaluable algorithmic trading logic, but the syntax and architectures of other platforms (Python, C++) are completely different.
Myth #10: I can only buy quality tools from the official MQL5 Market. REALITY: The Market offers convenience and a filter, but due diligence (checking history, testing in demo) is always necessary. Quality depends on the developer and the strategy's logic, not just the platform.
