Learn from my experience as a software developer creating Forex algorithmic based on the market's "mood," which can follow a number of chart patterns. In forex trading, avoiding large losses is more important than making large of possible lines of technical analysis that a trader can apply to a chart. Here are the basics of constructing an indicator. Unique indicators can be developed only with core elements of chart analysis, while hybrid indicators.

Once I built my algorithmic trading system, I wanted to know: 1 if it was behaving appropriately, and 2 if the Forex trading strategy it used was any good. In other words, you test your system using the past as a proxy for the present.
MT4 comes with an acceptable tool for backtesting a Forex trading strategy nowadays, there are more professional tools that offer greater functionality. To start, you setup your timeframes and run your program under a simulation; the tool will simulate each tick knowing that for each unit it should open at certain price, close at a certain price and, reach specified highs and lows. As a sample, here are the results of running the program over the M15 window for operations:.
This particular science is known as Parameter Optimization. I did some rough testing to try and infer the significance of the external parameters on the Return Ratio and came up with something like this:. You may think as I did that you should use the Parameter A. Specifically, note the unpredictability of Parameter A: for small error values, its return changes dramatically.
In other words, Parameter A is very likely to over-predict future results since any uncertainty, any shift at all will result in worse performance. But indeed, the future is uncertain! And so the return of Parameter A is also uncertain. The best choice, in fact, is to rely on unpredictability. Often, a parameter with a lower maximum return but superior predictability less fluctuation will be preferable to a parameter with high return but poor predictability.
In turn, you must acknowledge this unpredictability in your Forex predictions. This does not necessarily mean we should use Parameter B, because even the lower returns of Parameter A performs better than Parameter B; this is just to show you that Optimizing Parameters can result in tests that overstate likely future results, and such thinking is not obvious.
This is a subject that fascinates me. Building your own FX simulation system is an excellent option to learn more about Forex market trading, and the possibilities are endless. The Forex world can be overwhelming at times, but I hope that this write-up has given you some points on how to start on your own Forex trading strategy. Nowadays, there is a vast pool of tools to build, test, and improve Trading System Automations: Trading Blox for testing, NinjaTrader for trading, OCaml for programming, to name a few.
Here are a few write-ups that I recommend for programmers and enthusiastic readers:. Forex or FX trading is buying and selling via currency pairs e. Forex brokers make money through commissions and fees. Forex traders make or lose money based on their timing: If they're able to sell high enough compared to when they bought, they can turn a profit.
My First Client Around this time, coincidentally, I heard that someone was trying to find a software developer to automate a simple trading system. MQL5 has since been released. For example, Bollinger Bands are simply fixed percentages above and below a moving average.
This mathematical function gives a clear price channel showing support and resistance levels. Hybrid indicators use a combination of existing indicators and can be thought of as simplistic trading systems. There are countless ways in which elements can be combined to form valid indicators. Here's an example of the MA crossover:.
This hybrid indicator utilizes several different indicators including three instances of the moving averages. One must first draw the three-, seven- and day moving averages based on the price history. The rule then looks for a crossover in order to buy the security or a cross-under in order to sell. This system indicates a level at which price movement can be expected and provides a reasonable way to estimate when this will occur as the lines draw closer together.
Here's what it might look like:. A trader can create an indicator by following several simple steps:. Suppose we want to create an indicator that measures one of the most basic elements of the markets: price swings. The goal of our indicator is to predict future price movements based on this swing pattern.
We look to develop a unique indicator using two core elements, a pattern and math functions. Looking at weekly charts of company XYZ's stock, we notice some basic swings between bullishness and bearishness that each last about five days. As our indicator is to measure price swings, we should be interested in patterns to define the swing and a mathematical function, price averages, to define the scope of these swings.
Now we need to define the rules that govern these elements. The patterns are the easiest to define: they are simply bullish and bearish patterns that alternate every five or so days. To create an average, we take a sample of the duration of upward trends and a sample of the duration of downward trends. Our end result should be an expected time period for these moves to occur.
To define the scope of the swings, we use a relatively high and a relative low, and we set these at the high and low of the weekly chart. The direction and duration of the move, again, is determined by the pattern. We take this strategy and test it manually, or use software to plot it and create signals. Finally, we go live with this concept and trade with real money.
Building your own indicator involves taking a deeper look into technical analysis and then developing these basic components into something unique. Ultimately, the aim is to gain an edge over other traders. Just look at Ralph Nelson Elliott or W. Their successful indicators gave them not only a trading edge but also popularity and notoriety within financial circles worldwide.
