Constructing a Forex Trading System - Part 1

CONSTRUCTING A FOREX TRADING SYSTEM - PART 1

 

Before beginning our construction of a forex trading system we need to know whether our system is going to be purely rules-based and fully mechanical, or discretionary, or a mix of both (the most popular ones). We shall keep in mind that there are hundreds of systems available on the Internet trading forums, and I shall be posting several of the better ones on my blog, with the permission of the originators. But for now, we are going to build our own “from the ground up.”

 

WHAT KIND OF SYSTEM?

 

It would be wise for us to stick to purely rules-based trading for our first forex trading system. I say this because beginner-traders usually trade with their emotions, and with poor knowledge of how markets, indicators and charts really work. For inexperienced traders to be making discretionary trading decisions based on what the account balance is doing, can cause panic and uncertainty.

 

Mechanical Trading Systems can always have a degree of discretion added later on, as traders grow in trading wisdom and experience. For example, it might be ok to simply take a “buy” trade because the rules say so, but to be buying when price is almost hard up against a strong resistance level, is not something an experienced trader would be looking to do. Therefore, discretion to ignore that signal would be used, and the trader would wait with interest, to see if a “sell” signal developed after testing the resistance level. There is far more to that situation, of course, but enough for now.

 

FIRST PRINCIPLES … things we need to know and consider

 

Right now we will keep our trading system simple. All we need to know is how to “read” the chart, so as to understand what kind of probability we have of price going higher/lower, and how to get into and out of that trade in the best possible places. In order to profit through trading, we need to be along for the ride when price moves … simple.

 

Buy when price is going up … sell when price is going down … right?

 

Well … yes … and no. Quite often much of the move is over by the time we visually recognise a change in the trend. Or the move is short-lived, and reverses or moves sideways before we can take a position, or establish any profit. But sometimes a strong trend commences, and it is these trends that make us the money in trading, providing we recognise an entry in good time.

 

I should state here that many traders start their trading careers by trying to scalp the market. While I have no opinion on what you should or should not do, I would just say it is something that I would not be looking to do myself as a beginner. Why? Because scalping requires specialist knowledge of the instrument traded.

 

The moves can be fast and furious – as can be the reversals. Traders need very well-developed reflexes to know and understand and judge what might be going on in the market when certain moves occur. Experience can tell the trader if the move is a reversal, or volatility. A novice trader would not be expected to understand or know how to handle that.

 

Volatile price moves could be fake-outs, designed to shake weak hands from their positions. Or they could be just knee-jerk responses to news, causing great price swings before settling down again, and the previous trend, more frequently than not, resumes.

Such trading occurs in the lower time-frames like the 1 minute and 5 minute and even the 15 minute charts. Traders of the higher time-frames, like the 1 hour, 4 hour and Daily time-frames call this “noise” and avoid trading it. It usually has little to do with the main trends.

 

So let’s make our first decision based on time-frame to trade. For the purposes of this exercise, we’ll choose the 4 hour. This is a time-frame that gives us plenty of time to analyse, and is not easily moved by news announcements, or sentiment. And if there is going to be a change of direction, this time-frame usually sends signals to traders that it is going to do that, in time to react to what price is doing. Our decision will be unhurried, and low-stress.

 

I should add that after we construct our forex trading system, we will be able to apply it to other time-frames too. Price action is said to reflect the thinking of the market participants, and the price activity seen in the chart is the manifestation of what the market was collectively thinking at that time.

 

Well … we didn’t get far today. I had hoped to define all the parts of the trading system, but I can see it is a bigger task than I realised. I did discover one thing though, and that is if we are going to create a trading system, we have to define every component. There are sound reasons for that.

 

I have never been one to simply put indicators or trend-lines or moving averages on a chart and expect to be able to make a trading decision based on what I can then see.

 

If I have something on my chart, then I need to know it has earned the right to take its place there. I will have an expectation of it, to tell me its secrets. I need to have as many indicators and filters on my charts as I need to confirm my actions … but not more. If there are too many, then the purpose of having them there is defeated. Each filter chokes back the opportunities more. Each moving average and indicator screams “Look at me!” and soon you have a series of conflicting signals.

 

We don’t want that. We want to keep it simple, and meaningful. We need to be able to look at every object on out charts, and KNOW why they are there, and WHAT it is that they are telling us.

 

We'll take this further next time ... and hopefully get some real progress on designing our own strategy and system.

This is why it's best to use maximum 3 indicators rather than filling your charts with lines, dashes and clouds.
