Forex Trading System: Discretionary vs. Mechanical Systems
There are basically two types of Forex trading systems, mechanical and discretionary systems. The trading signals that come out of mechanical systems are mainly based off technical analysis applied in a systematic way. On the other hand, discretionary systems use experience, intuition or judgment on entries and exits. But which one produces better results? Or more importantly, which one fits better your trading style? We will first analyze the pros and cons about each system approach.
Disadvantages They cannot be backtested or automated, since there is always a thought decision to be made. It takes time to develop the experience required to trade successfully and track trades in a discretionary way. At early stages this can be dangerous.
Now, which approach is better for Forex traders? The one that fits better your personality. For instance, if you are a trader that finds it hard to follow your trading signals, then you are better off using a mechanical system, where your judgment won’t play an important role in your system. You only take the trades that your system signals.
If the psychological barriers that affect every trader (fear, greed, anger, etc.) puts you in unwanted scenarios, you are also better off trading mechanical systems, because you only need to follow what your system is telling you, go short, go long, close a trade. No other decision has to be made.
On the other hand, if you are a disciplined trader, then you are better off using a discretionary system, because discretionary systems adapt to the market conditions and you are able to change your trading conditions as the market changes. For instance, you have a target of 60 pips on a long trade. But the market suddenly starts trending up pretty strongly, then you could move your target to say 100 pips.

Trading discretionary systems means that once a trader finds his/her setup, the trader then decides what to do. But every trader still needs certain rules that need to be followed, such as the size of the position, conditions that have to be met before thinking to get in the market, and so on.
Whether you choose to be a discretionary or a mechanical trader there are some important points you should take in consideration:
