From the differences, an automated trading system may seem like the best choice because it is great at following rules without emotion, will not panic when the market drops, or wears its greedy boots when the market goes up. But it does not read that candlestick and take a break at a bullish turn as a manual trader will, doesn’t make real-time decision-making, implements immediate strategy adjustments, and applies emotional intelligence in its dealings. So, their differences might likely be a compliment to each other.
