The middle line is just the Simple Moving Average. Note, the high bearish volumes at the bottom, which appeared right after the divergence and right before the drop of the price. Here we compare the current stock price, P , with the smallest and largest stock prices over the past N days: Click 'Overlay indicator' to add an additional Plot to an existing Area. If you need to sort by a column that is not shown, use 'Customize Grid Columns' first to add the column. To add a trend line just click 'Add Trend Line'. If you have difficulties understanding the VWMA, just open a volume indicator at the bottom of your chart.

Just the opposite is true; it is well recognized by practitioners that such price series are very commonly serially correlated [ citation needed ] —that is, each price will be closely related to its ancestor "most of the time".

Adjusting for serial correlation is the purpose of moving standard deviations , which use deviations from the moving average , but the possibility remains of high order price autocorrelation not accounted for by simple differencing from the moving average.

For such reasons, it is incorrect to assume that the long-term percentage of the data that will be observed in the future outside the Bollinger Bands range will always be constrained to a certain amount. Practitioners may also use related measures such as the Keltner channels , or the related Stoller average range channels, which base their band widths on different measures of price volatility, such as the difference between daily high and low prices, rather than on standard deviation.

Bollinger bands have been applied to manufacturing data to detect defects anomalies in patterned fabrics. The International Civil Aviation Organization is using Bollinger bands to measure the accident rate as a safety indicator to measure efficacy of global safety initiatives.

That's the are you ready for this R elative S trength I ndex or RSI which measures the percentage of times when the stock Price increased over the past N days.

Here's a graph of what the RSI might look like If Bolli-bands don't improve your financial health you might want to try band-aids Indeed, John Bollinger's words are: Here we compare the current stock price, P , with the smallest and largest stock prices over the past N days: If these are L and H respectively, then we determine how far up the range from L to H that the current price lies. We go long with the second bullish candle after the breakout of the range and we enjoy the impulsive move higher.

Here we have a simple rule, if our volume weighted moving average is between the chart and the simple moving average, then we have a signal for a trending market. Note that sometimes the volume weighted moving average will test the simple moving average as a support and resistance, depending on the primary direction of the security.

These tests can be considered as an implication of a potential trend reversal. Take a look below:. This is a M5 chart of Google from July 22 nd , 23 rd and 24 th from If you check a half an hour later, you will see that the blue VWMA is still below the red SMA, which means that the bearish trend is still intact. The arrows show the moments, where the VWMA provided a signal for the continuation of the bearish trend.

If we were to go short at any of these points, we would not be disappointed. The last red arrow shows us the moment when the bearish trend shows signs of slowing down as the VWMA and SMA begin to hug one another.

This signal is pretty much the same as when we had to discover emerging trends. The difference is we are looking for a contrary signal to the primary trend.

This is the moment where you might want to consider the option to get out of the market and to collect your profits. The above chart is of Facebook from July 16 th — 22 nd. Facebook begins the week with a strong gap up with high volume. Therefore, we go long with the closing of the first bullish candle.

Facebook keeps increasing until the volume drops and the market enters a correction phase. We hold our position for about 20 more periods and we nearly double in our long position. We believe periods of waiting are enough in order to realize that this is the right moment to close our position. After we exit our position, the price of Facebook starts to rollover and eventually breaks down through the moving averages.

Exiting Facebook at the right time brought us a profit of about 55 bullish pips!

Bollinger Bands. show the volatility of a stock based on Standard Deviation around a Simple Moving Average. The bands widen when volatility increases and narrow when volatility decreases. Calculation. Bollinger Bands have 3 lines. The middle line is just the Simple Moving Average. Writing upperBB for the upper Bollinger Band, lowerBB for the lower Bollinger Band, and last for the last (price) value: % b = (last − lowerBB) / (upperBB − lowerBB) Bandwidth tells how wide the Bollinger Bands are on a normalized basis. There are jillions of Weighted Moving Averages; pick your weights as the periods of oscillation of a butterfly wing and you've got yerself another WMA. Most play with just the stock price and ignore the volume of stock traded at that price.
