Backtesting The Forex Metatrader 4 Demo - Pros and Cons

There are various ways to review trading systems, the most common being back testing and demo-ing. Many people hold the belief that “if it ain’t broke, don’t fix it.” Likewise, if the system does not work, a revision of the system is needed.

There are pros to using back testing and demo-ing to review a system.

1. Detecting patterns in history. The back-test can reveal patterns that work or don’t work.

2. In order to maximize potential, investors should learn important quotients like max draw-down so they have an understanding of the program.

3. Trust is built that can sustain the investor while waiting for results. This trust allows the investors to take chances they may not have otherwise taken when trading.

4. Using back-testing investors can replicate the performance statistics of a system, allowing them to accurately estimate the probability and magnitude of any possible trade profits.

Downfalls of Utilizing Demo-ing and Back testing

1. Spreads

Spreads can narrow at the slightest sign of surprising news. You might also find differences in the spreads between night and day. The bid and ask prices of the trades might not be able to truly reflect the spread width.

When back-testing, you won’t be able to tell as well just how these conditions will turn out, making them unreliable.

2. GMT Difference

Daylight Savings Time in the U.S. and U.K. may cause the server to fluctuate. The time on the tables will likely not align with the historical data. The result of the time difference is that those tactics utilizing blocks of time in their equations to determine pricing will be skewed.

3. Brokers’ Control

Agents will use demo-ing and back testing to present the best possible option. Live trading does not reflect such perfect scenarios. Agents manipulate the data to make their skills more appealing, thereby attaining more customers. The Internet has a wealth of information regarding forex forums.

4. Trade Entry Strategy

Trading live may not give you the opportunity to purchase at the price you expected based on the system used to compare data. Truthfully, the market price being in a constant state of flux is not conducive to physically initiating the trade at the optimum amount. Live trading allows for disparity in prices from demo-ing or back-testing.

Conclusion

If we’re honest about how demo tests and backtests can fall short, we can have a better knowledge of the nuances of the trading system, recognizing the pros and cons of each system. Despite all of the limitations of backtests, they are still quite a few things they get right.
