Automated Trading Systems | Backtesting in strategy tester – Wetalktrade

Automated trading systems are programs that place orders on behalf of the trader. A trader sets the prerequisite condition for order placement based on technical analysis principles. The system will place orders automatically on the satisfaction of the necessary conditions.  The automated trading system facilitates backtesting (strategy tester in MT4) on a demo account which gives a fair idea of the efficiency of the strategy.

The necessity for Automated Trading

Emotion and trading are like twins. You can’t separate one from the other, and the former has a bad influence over the latter. The best way to nullify emotions like greed and fear is to avoid manual intervention and place orders with the help of automatic trading systems.

Creating strategies for Automated trading

The trader has to develop strategies on his own, based on either algorithmic or high-frequency trading concepts. Similarly, a trader can also buy tailor-made automated trading applications from the market, but the reliability and cost are the major hindrances in doing so.

Key Traits of the strategy


High-frequency traders are those who require an automated trading system. A trade setup which repeats itself many times a day are the ideal ones to be automated. If not many times, it should repeat itself at least twice or thrice a day. Above all, the relevance of an automated trading system solely depends on the recurrence of the strategy.


A strategy should apply to different time frames and in many counters. If the strategy applies to more than one market, it is better. The more the applicability extends, the merrier the strategy is, as it validates it.


It’s a no-brainer. The strategy should be accurate and yield consistent returns. And so it is essential to define a suitable risk-reward ratio. The efficiency of a more recurring set up should be high. It is okay to observe leniency in accuracy for high yielding but low frequent strategy.

Blessings of Automated trading

Benefits or Positives of Automated Trading System

Swift Entry and Exit

Many traders develop quick in and out strategies for scalping and day trading. Each second and each tick are valuable to those strategies. Automated trading systems can only match the speed and required by those traders.  (If you are a scalper, check out our product Expert trading panel, which offers 5x order execution speed)


Backtesting a strategy for its accuracy and vulnerability is of eminence.  An approach works in the specific market well, say in stocks, but not in other markets like forex. Some strategies perform well only in particular timeframes. Hence a detailed feasibility and viability study of the strategy is made before using it on the live market. The studies offer the best insights to the trader. Therefore the decision making becomes simpler.

Nurtures discipline

Emotion is the arch nemesis of discipline. Hence, they never coexist together in a system. It is important to take down the emotion to be consistent and automated trading is the best weapon to do so.  It is also easier to implement strict discipline in a system with little or no human intervention. (Want to know the benefits of robot trading?

Unforeseen Events

The reason traders are glued to their trading screen is that markets are naturally deceivable. By virtue of experience, a trader can predict certain outcomes, but not all of it. An unforeseen event can trigger volatility and instigate movement in both directions. Even after the ups and downs, a trade setup can remain the same. Therefore, a human intervention could be the need of that hour.
