Code “Mark Larsen – Bollinger Strategy”

Reversal Patterns with Bollinger Bands Indicator

Bollinger bands actually comprise three separate indicators and each tells you something about the price activity at a current point in the chart. This article looks at the Bollinger indicator, what each component of the indicator means.

When the strategy is incorrect, the bands are still broken and you'll find that the price continues its decline as it rides the band downward. Unfortunately, the price does not rebound as quickly, which can result in significant losses. In the long run, the strategy is often correct, but most traders will not be able to withstand the declines that can occur before the correction. The selling pressure was clearly in oversold territory.

The strategy called for a buy on the stock the next trading day. Like the previous examples, the next trading day was a down day; this one was a bit unusual in that the selling pressure caused the stock to go down heavily. The selling continued well past the day the stock was purchased and the stock continued to close below the lower band for the next four trading days.

Finally, on March 5, the selling pressure was over and the stock turned around and headed back toward the middle band. Unfortunately, by this time the damage was done. The strategy calls for buying Apple shares on December The next day, the stock made a move to the downside. This is case where the selling continued in the face of clear oversold territory.

During the selloff there was no way to know when it would end. There are times, however, when the strategy is correct, but the selling pressure continues. During these conditions, there is no way of knowing when the selling pressure will end. Therefore, a protection needs to be in place once the decision to buy has been made.

The strategy correctly got us into that trade. Both Apple and IBM were different because they did not break the lower band and rebound. Instead, they succumbed to further selling pressure and rode the lower band down. This can often be very costly. Sellshort n shares at market. Sell at Average [ 14 ] close limit.

The existence of price chart patterns such as double tops and double bottoms can help identify buy and sell opportunities. When a rate reaches the highest level that the market is willing to pay - that is, the resistance level - the rate usually holds at the level creating a second plateau more, or less equal to the previous level.

This is the second part of the double top and if the rally is to be extended, the second top may be slightly higher. If the subsequent top is lower, this is seen as a signal that a rate reversal is imminent as traders sell their positions, or short the currency pair outright in anticipation of a drop in the exchange rate.

A double bottom is basically the same as a double top, but is seen as a signal that the support level for an exchange rate has been reached resulting in an increase in the rate.

This is because once the market is prepared to support the rate from dropping further, buyers enter the market in an attempt to buy into the currency pair at a low point prior to an upswing.

In this example, after several closes below the support level, the exchange rate reversed its direction shortly after posting a double-bottom. A double-top signified the end of a series of intra-period closings above the top band the resistance level indicating a rate reversal. John Bollinger believed "20,2" to be the optimal setting for most situations. In this example, the settings in the top left corner are circled.

These numbers indicate the time periods used to calculate the moving average "20" and the standard deviations away from the moving average to position the upper and lower bands "2".

With the OANDA platform, you have the ability to experiment with these settings, but please keep these two points in mind if you do experiment:. Keep most of the exchange rate fluctuations within the bands. If spot rates break through the bands too frequently, it will become impossible for you to distinguish between a typical fluctuation and a possible reversal signal.

If market rates rarely break the bands, consider reducing the number of reporting periods for which the average rate is calculated.
