Tutorial Forex

When you want to determine if a trading system is going to be valuable to you, you must preform back testing and demo-ing. This is based on the theory that if a strategy worked well for others, it will work well for the new user. On the other hand, if a strategy did not work well for others, it will fail to work well for the new user.

Benefits Of Doing Demo-ing and Back-testing Evaluations

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.

Disadvantages of Backtests and Demos

1. Ranges

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.

Not all tactics are appropriate for the situation, such max spread conditions are best used for back-testing rather than live trading.

2. Counterbalancing GMT

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

There are some brokers who will present nearly ideal trading conditions during a back-test or demo test. However, in live trading ideal conditions are not a reality. The brokers preform this manipulation in order to make more traders want to utilize their services. You can get more information on this topic through online forex forums.

4. Trade Entry Strategy

If your system entries are done through market order, you might not find it too easy to acquire what you want at the right price. When you go live, your market price is a lot more fluid than in back-testing, making it hard to get to the best price for your needs. You can’t accurately predict how the entry price will go in live conditions through 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.
