Bollinger Bands are a widely used technical indicator for measuring and displaying the volatility of securities. The bands accomplish this by showing whether prices are high with the use of an upper band, and whether they are low with the use of a lower band. The bands are based on the volatility (standard deviation) of the past price data. The research in this thesis develops two modified models, one combining neural networks with the Bollinger Bands technical indicator, and another incorporating a GARCH-in-mean model with the Bollinger Bands technical indicator to predict and trade on the security trend. And the historical risk is measured by maximum drawdown. We compared three main strategies: percentage, standard deviation of cointegration long term residuals and Bollinger Bands (dynamic standard deviation), with and without double confirmation of short term standard deviation modeled by ECM-DCC-GARCH. lower exit band L x (t) = M(t) – S(t) * E x These bands are actually the same bands as in Bollinger Bands indicator and we can use crossing of R(t) and bands as trade signals. We open short pair position, if the Z-score Z(t) >= E n (equivalent to R(t) >= U n (t) ) Jul 07, 2019

(eg: ARIMA & GARCH models), machine learning (eg: SVM or Neural Networks on features derived from stock prices), and chartist tools (eg: Bollinger Bands). 8 Dec 2019 On the other side of the coin, many take issue with the GARCH VIX with two standard deviation Bollinger Bands around 10-day SMA Ли́нии (по́лосы) Бо́ллинджера (англ. Bollinger bands) — инструмент технического анализа финансовых рынков, отражающий текущие отклонения цены "Bollinger Bands" are a technical analysis tool developed by John Bollinger in the 1980s for trading stocks. The bands comprise a volatility indicator that
Developed by John Bollinger, Bollinger Bands® are volatility bands placed above and below a moving average. Volatility is based on the standard deviation, which changes as volatility increases and decreases. The bands automatically widen when volatility increases and contract when volatility decreases.

Jul 07, 2019 · As illustrated by the Bollinger Bands (which depicts volatility), the GBP/EUR exchange was extremely volatile, spiking between the lower and upper bands. However, around the time of June 2016 (Brexit Vote), the exchange rate suffered a devastating negative impact, which resulted in the constant hitting of the Bollinger lower bands of volatility.

An adjusted Bollinger band generated by rolling GARCH regression method is proposed in this study. The performance of the adjusted Bollinger band strategy on EUR, GBP, JPY, and AUD vs. USD foreign Bollinger Bands are calculated at a specified number of standard deviations above and below the moving average, causing them to widen when prices are volatile and contract when prices are stable. Bollinger originally used a 20 day simple moving average and set the bands at 2 standard deviations, suited to intermediate cycles .
The assumption of the combined system is that the neural network or GARCH model will help to overcome the lagging aspects of the Bollinger Bands indicator by providing a next day forecast, allowing the trader to make the correct trading decisions.
Bollinger Bands are a technical analysis tool, specifically they are a type of trading band or envelope. Trading bands and envelopes serve the same purpose, they provide relative definitions of high and low that can be used to create rigorous trading approaches, in pattern recognition, and for much more.
