Both automated trading tools and foreign exchange indicators should first undergo backtesting, simulated account observation, and small capital verification. Pay special attention to spreads, slippages, maximum drawdowns, position opening frequency, stop loss methods, trading periods and broker rules, and avoid direct real-time execution based only on titles or short-term profit descriptions.
