There are two main criteria by which you must program the rules, and it's – Introduction to market and exit from the market or your stop. You can use a great number of indicators in a timely manner to carry out their transactions, but in the automated trading system, you need to use as little as possible here, I'm going to show you how to build a system of rules 1, simply relying on the trading volatility.
A very simple system is based on the standard deviation (volatility) price. For example, Bollinger range middle strip shows average level and two external lines, with a standard deviation from the normal or average level, since the volatility increases strip extending from the middle. You can easily build a simple system variability with its own settings, so that's what you're doing.
You must decide the midline of the moving average line to start. Here, prices will find support in the bull market and resistance in a bear market. A buy signal is generated (and kept) in the bull market, if the average is broken, the outer lower band to provide the level of termination.
What you need to do is to check out the different moving averages and standard deviations of the parameters for the outer bands, but it's easy to do with today's software. Then you will need to decide on the distribution of currency to trade it and test it over time to see how it is successful – because it has only one rule, it will show a realistic test for a return performance.
the aforementioned logic of the system is easy to understand, and below, you will find how to generate a buy signal and a stop on the bullish market.
In the context of a strong bull prices may deviate from the average price, but they usually find support compared to the average. If the transfer price volatility through the middle lane to the outside of the lower band, the probability of changes in demand and supply changes from bullish to bearish and the stop can be placed
You should do a little research, and you can add additional filters if you want, but the system is based on the instability, if the spread of uncontrolled trade in the contracts will run (they very rarely work on a contract).
I've seen people make great incomes with simple automated systems, and you too can. Of course, you have to spend some time on research and testing, as well as any trading system in the long run, but if you do a little work, you can easily create your own automated Forex trading system and to make big profits at least 30 minutes per day.
