Mechanical “systems” are for gamblers. For example, most trend following systems/set-ups have you entering the trend when it is almost at a major support or resistance level, then have you exit worse than break-even. Or worse yet, they’ll have you entering right at a trend line break out so you are stuck in a 10 pip trading range for three days.
You’ll find that most systems will be okay 30-40% of the time as long as the exact conditions the system was designed for are met. The problem is, if you try to operate that trend following system in a primarily ranging marking, you will eventually lose a lot of money, and then give up. You will be trying to find another “system.”
The better way is to have the training and experience to trade any time of day, in any market, with any instrument, under all conditions. This will take hundreds of hours of study and practice. It takes reading and studying. It may even take several hundred or even thousands of dollars to get the right education. But it is well worth it.
You will know how to trade trends: breakouts, tight channels, broad channels. You’ll know when to enter during a trading range. You’ll be skilled at reversals. you’ll know which currency pairs are moving and which ones are flat. In other words, you will be able to adjust as market conditions dictate, rather than have an inflexible, mechanical system do the trading for you.
The best thing I ever did was drop the “systems” and “secret set-ups,” and instead, invest my time and money (not a huge amount of money) into learning price action trading.
All the best to you as you pursue your trading career.
