Trading strategy can also be known as the set of rules for making trading decisions that are beneficial for the traders. These strategies are followed to eliminate the emotional aspect of trading for making it more beneficial. Sometimes humans take decision under the influence of emotion which creates lots of problem for them and to avoid such situation and resulting losses, trading strategies have been made. In other words, it promotes wiser decisions and thus, helps in making successful trading decisions. It is governed by a set of rules that never deviates hence, maintain consistency in the trading decisions.
While defining some rules for trading strategy in automated or algorithmic trading, some parameters are defined on which the trade decisions depend. In the world of information technology, the most important thing is the optimization of parameters on which the entire trading is based. Defining trading strategy needs expert handling so that effective decisions can be taken while entering the trade. Since the modern trading is based on some mathematical algorithms, the computer programs that make use of these algorithms have good number of parameters.
While developing a trading strategy, several things are taken into consideration such as volatility, timeframe, risk, return, methods etc. to make the strategy most effective and fruitful. These make the parameters and their optimization is necessary to add effectiveness to the trading strategy. The first step of the optimization is to decide the good factor of the parameter means that can make the most money so that you can have better trade. This vision of making most money per trade makes your trading strategy most effective.
The only goal in the financial trading is to make most of money and for this effectiveness of the trading strategy is must to have that is in turn set by the parameters. Many devices are used to optimize the parameters and traders also do it manually, which is commonly used for optimization. For smaller quantity of data brute force optimization method is used. This method makes every possible combination of the available parameters and then evaluates its usability and effectiveness. Sometimes data are present in huge amount and you need to enter multiple trades at a time then it becomes almost impossible to do the entire needful manually. There are multiple optimization techniques that have their own characteristics. Backtesting is a good method to decide the effectiveness of the strategy as well as parameters. It gives an idea that the strategy has worked in the past hence, it has chances to give desired results in the future.
