Thus, it seems reasonable to try and improve on our original signal with additional rules. Usually, when a trader looks at a chart they take into account all sorts of different information.

The Amibroker code for this price signal is shown below: We need price to trade through the line to get the signal. Note that the high of the day must be higher than the 200 day MA and the low of the day must be lower than the 200 day MA to get our signal. The previous chart that was shown above is a good example of the trade we are looking for. Once the stock has traded through the 200 day MA we go long on the next open and sell after a period of time. The signal looks for stocks that have been above their 200 day moving average for over 100 consecutive days which then drop back towards the 200 day moving average and trade through the indicator line. To test the effectiveness of the 200 day moving average pullback (or bounce) signal I created some code in Amibroker and back-tested the signal on historical data on S&P 500 stocks between 1/2000 and 1/2017 with various holding periods.

In this event, the stock will fall below the entry price and the trade will be a loser. However, not every stock that pulls back to the 200 day moving average is going to carry on in an upward trend and some will shoot through the indicator and carry on heading south. It also means that the trader is able to rejoin the trend without having to buy at new highs, a technique that can often lead to sharp whipsaws.
The benefits of using the 200 day moving average as an entry is that it gives traders the chance to re-enter a trend that they may have missed. The 200 day MA acts as an area of support and the stock bounces off this level and resumes its upward march. It pulls back towards the 200 day MA in Feb 2016.

In this article I look at a strategy that buys upward trending stocks as they pull back towards the 200 day moving average line. When a stock is above the 200 day MA, it’s said to be in an uptrend and when it’s below, it’s said to be in a downtrend. The 200 day moving average is an extremely popular indicator among traders and trend followers. By Joe Marwood Amibroker Stocks Strategies/ Systems Top Posts July 13, 2017
