Author: It was in Japan that ground pool paper lanterns appeared for the first time. The Japanese people would pay their respects to the dead by leaving them to float gently on the surface of the water. Other civilizations have borrowed ground pool paper lanterns, their uses varied with the passing of time. They are still used in Japan to this day as a gesture full of rich meaning. Not surprisingly, people in America have found themselves powerfully attracted to ground pool paper lanterns, using them in weddings and other important events. Nowadays, seeing ground pool paper lanterns set afloat on the surface of the water is not something out the ordinary.
If there is one thing you cannot complain about, it would be the diversity of choices offered for ground pool paper lanterns. Whether the main event is a wedding or anything else for that matter, we should not be surprised to discover that the lotus flower is one of the most popular choices. Made from waterproof materials, ground pool paper lanterns are more interesting when they represent certain symbols or have unique colors and patterns. If the paper lantern has a LED light that switches from one color to the other, this decoration becomes a must-have without any doubt. Imagine how beautiful your ground pool paper lanterns will look floating on the water!
What is Backtesting? (Part II)
The second method of Backtesting is performed manually and visually by the trader. The trader would take the historical data and scroll back in time on a chart and manually apply the trading strategy as if it was in a real time environment.
One of the major drawbacks with manual Backtesting is hindsight. How to eliminate the hindsight factor while doing manual Backtesting? The trader would advance the chart bar by bar in order to refrain from seeing price action subsequent to the trade at hand. This eliminates trading in hindsight that is detrimental to an objective backtest.
The major disadvantage of Backtesting as compared to automated testing is the significant potential for human error in executing simulated trades and recording performance results. Manual Backtesting is complicated and difficult. It requires a lot of patience on part of the trader.
Additionally the normal range of human emotions and biases that often interfere with actual trading can be a detrimental factor in achieving objective backtest results. Furthermore, it takes a great deal of work and discipline to simulate trades manually over a large data set without straying from the strict rules of the trading strategy.
