The biggest mistake is vague scope
A trader may ask for an EA that follows a strategy, manages risk, filters news, sends alerts, and works on every symbol without defining the details. That creates confusion before development begins.
A developer can code rules, but they cannot reliably guess a trader's unwritten discretion. Vague scope usually leads to delays, revisions, and mismatched expectations.
Mistakes to avoid
A better project starts with a short but specific brief. The trader should describe the expected behavior, attach examples, and separate required features from nice-to-have ideas.
The trader should also understand that backtests, demo tests, and live execution can differ because of data, spread, slippage, broker rules, and timing.
- Starting without entry, exit, and risk rules.
- Expecting the developer to invent the strategy.
- Ignoring edge cases and broker constraints.
- Skipping demo testing after delivery.
- Changing requirements without updating the specification.
What a professional process looks like
The project should move from requirements to build, then to review, demo testing, bug fixes, and documentation. Each stage should answer a different question.
Good developers also explain limitations. That includes what the EA can automate, what remains manual, and what market risks cannot be coded away.
Treat the EA as software, not a shortcut
A custom EA is a tool that executes logic. The quality of that tool depends on the quality of the strategy definition and the testing process.
If you need a custom EA, TradingView indicator, Pine Script alert tool, trade copier, Telegram workflow, dashboard, or scanner, Swiftfolio Automation can help map and build the tool.
Trading involves risk. Swiftfolio Automation tools do not guarantee profit and do not provide financial advice.
