Bande di Bollinger (BB)

Exponential Bollinger BandsThese Bollinger Bands are exponential because the variance is calculated using the exponential moving average, rather than just adding the normal standard deviation to the ema. This may be more useful because the exponential standard deviation should be more sensitive to near term increases or decreases in volatility. Please do not forget that Bollinger Bands should always be combined with another method of analysis. Bollinger Bands just provide an easy way to gauge where the price could range in. At 2 standard deviations of a continuously random variable, more than 98% of data points are in this range. I am however going to test this in excel to get the average number of data points that stay in the range for Bitcoin. I will upload my findings when I complete that. Please monitor this description if your interested.

BL_MTF River Strategy with TP/SL by Beller Anyone remember the "Frogger" game where a frog must pass a river ? This strategy is like a game. Immagine you that the cyan lines are a River, any time the price can cross up or down this river, you must buy or sell only when the bar are dry.. BUY at highest price of the first bar that is completely dry over the river SELL at the lowest price of the first bar that is completely dry under the river Stoploss is placed at the river bands, take profit is placed at 1:1 and 1:2 ratio, a risk money management must be applied. This strategy can be used with multiple time frame, i'm testing it in 15min,180m and daily base applyed to EURJPY. It's a game but can produce some money... ;-)

UCS_Squeeze_Timing-V1There is an important information the Squeeze indicator is missing, which is the Pre Squeeze entry. While the Bollinger band begins to curves out of the KC, The breakout usually happens. There are many instances that the Squeeze indicator will fire, after the Major move, I cant blame the indicator, thats the nature (lagging) of all indicators, and we have to live with it. Therefore pre-squeeze-fire Entry can be critical in timing your entry. Timing it too early could result in stoploss if it turns against you, ( or serious burn on options premium), because we never know when the squeeze will fire with the TTM squeeze, But now We know. Its a little timing tool. Managing position is critical when playing options. I will code the timing signal when I get some time. Updated Versions -

Vervoort Smoothed %b [LazyBear]As we know, %b is a measure of where prices are in relation to the outer Bollinger bands and therefore strongly related to volatility. This can get choppy, though. Vervoort smoothed this using Zero lag TEMA of custom Heiken-ashi recalculated prices. According to Vervoort, "Smoothed Vervoort %b is often a leading indicator making smooth moves with clear turning points. Normal and hidden divergent moves make it an ideal tool to help find entry and exit points while watching price moving between the Bollinger bands."

CCT Bollinger Band OscillatorThe CCT Bollinger Band Oscillator (CCTBO), developed by Steve Karnish of Cedar Creek Trading, reconfigures John Bollinger's classic Bollinger Bands (envelopes plotted at two Standard Deviations above and below a moving average) by drawing two parallel lines replacing the envelopes. The parallel lines represent a measurement of two Standard Deviations from the mean and are assigned a value of zero and 100 on the chart. The indicator represents the price as it travels above and below the mean (50%) and outside the two standard deviations (zero and 100). Penetration of the upper band represents overbought conditions while penetration of the lower band signifies oversold conditions. Usage of the CCT Bollinger Band Oscillator to identify 'failure swings' and 'divergences' can lead to significant reversals. List of my other indicators: - Chart: - GDoc: docs.google.com

vdubongCustom script I fabricated which I use for Binary Trading on the 1m & 3m charts together with Price action & Time management but the principles are the same for all mediums. Use Price action buy/sell in the clear zones. Use the outer 'pink' horizontal lines (highs / lows / pivots points) to place SL's. I personally run an additional BB 50/2 for clearer BB higher highs & lower low perspective, but it's not part of the script. Script variables are fully customisable. I don't take ownership of any part of the script, I not a programmer /script writer just a dabbler. Enjoy :) - VDUBONG UPDATED

DEnvelope [Better Bollinger Bands]*** *** Bollinger Bands (BB) usually expand quickly after a volatility increase but contract more slowly as volatility declines. This extended time it takes for BB to contract after a volatility drop can make trading some instruments using BB alone difficult or less profitable. In the October 1998 issue of "Futures" there is an article written by Dennis McNicholl called "Better Bollinger Bands", in which the author recommends improving BB by modifying: - the center line formula & - different equations for calculating the bands. These bands, called "DEnvelope", follow price more closely and respond faster to changes in volatility with these modifications. Fore more indicators, check out my "Master Index of indicators" (Also check my published charts page for new ones I haven't added to that list): More scripts related to DEnvelope: ------------------------------------------------ - DEnvelope Bandwidth: pastebin.com - DEnvelope %B : pastebin.com Sample chart with above indicators: www.tradingview.com

BBImpulse IndicatorBBImpulse is part of the latest indicators package offered by John Bollinger. Excerpt from their market blurb (www.bbforex.com): "BBImpulse is derived from %b. Its value is the periodic change of %b, so if %b was 0.45 this period and 0.20 last period the present value of BBImpulse is 0.25. We present two reference levels on the chart, an alert level and an impulse level." "Generally the market moves in the direction of the latest alerts and/or impulses except towards the end of a move where one can take advantage of exhaustion/reversal signals from this indicator." "Ian Woodward employs BBImpulse for his Kahuna signals using key levels of 0.24 and 0.40." I added support for the following: - Highlighting alert/impulse trigger bars - Rendering the range (check options page). I noticed that the range, by itself, highlights lot of info: - Tapering in (narrowing) of range may signify topping or falling prices. - Tapering out (expanding) may signify nearing a bottom or rising prices. - Range getting "ranged" between alert or impulse levels signify a major move in the direction of the last impulse trigger. I think for this, alert level ranging intensity is greater than impulse level ranging intensity. Someone more familiar with BB will have more observations, I am sure. Please do share here so we BB noobs can learn :) For more indicators, check out my complete list here:

Indicator: Custom COG channelThis is my custom channel (Bear Channel!? :)) derived from BB/STARC. It uses both ATR/STDEV for plotting the bounds. I use COG (Center of Gravity) for deriving the baseline. This enables it to track the price action better than many other channels that make use of MAs or simply "close". Indicator also marks "squeezes" (stdev bands come inside ATR bands). Pay attention to these, as these usually indicate a move. I am still exploring this indicator on different BTCUSD time frames, would love to hear your feedback / setups for other instruments. Code for this indicator: pastebin.com Code for COG fibs I mentioned in the comments: pastebin.com

Trading Strategy based on BB/KC squeeze**** [Edit: New version (v02) posted, see the comments section for the code ***** Simple strategy. You only consider taking a squeeze play when both the upper and lower Bollinger Bands go inside the Keltner Channel. When the Bollinger Bands (BOTH lines) start to come out of the Keltner Channel, the squeeze has been released and a move is about to take place. I have added more support indicators -- I highlight the bullish / bearish KC breaches (using GREEN/RED crosses) and a SAR to see where price action is trending. Appreciate any feedback. Enjoy! Color codes for v02: ---------------------------- When both the upper and lower Bollinger Bands go inside the Keltner Channel, the squeeze is on and is highlighted in RED. When the Bollinger Bands (BOTH lines) start to come out of the Keltner Channel, the squeeze has been released and is highlighted in GREEN. When one of the Bollinger Bands is out of Keltner Channel, no highlighting is done (this means, the background color shows up, so don't get confused if you have RED/GREEN in your chart's bground :)) Color codes for v01: ---------------------------- When both the upper and lower Bollinger Bands go inside the Keltner Channel, the squeeze is on and is highlighted in YELLOW. When the Bollinger Bands (BOTH lines) start to come out of the Keltner Channel, the squeeze has been released and is highlighted in BLUE.
