Coin Bureau BB/EMA/RSI IndicatorThis indicator was inspired by Coin Bureau's How To Spot The Crypto Top video. In the video, Coin Bureau uses Bollinger bands, 7-period EMA and RSI to look for early signs of a top, thus presenting an opportunity to sell. Using the basic principles found in the video, I've made a tentative indicator as a way to visualise all 3 indicators at once. Alerts will only fire when all 3 criteria are met: Price closes outside 20-period Bollinger bands Price closes ~2sd away from 7-period EMA RSI is overbought or oversold The indicator will also update in real-time and show when 1, 2 or all 3 conditions are satisfied. Additionally, there is built-in functionality to toggle historical/current alerts and users can set their own bounds for what constitutes a buy or sell alert. This is just a personal project purely for edutainment purposes and should not be used to make financial decisions. This project is not affiliated with Coin Bureau. Some caveats: Using only 7 periods to calculate the standard deviation of price data will not lead to a statistically significant result, thus this figure may have no right being in the script. However, this was more to trial some techniques and to get acquainted with the pine scripting language. As you can see, there are a lot of false positives. There are moments when the indicator flashes a sell alert only for the price to keep on rising. This is due to the specificity/sensitivity trade-off. The indicator has been tuned to give the optimal sensitivity (the more critical component). These are the best results I could find for this asset in this time frame.

[jav] Better Bollinger BandsBetter Bollinger Bands (BBB) This script is a modification of classic Bollinger Bands (BB). CHARACTERISTICS Main improvement over BB: There is no need to introduce a standard deviation multiplier (usually 2). Here, only a length is needed (usually 20 bars for BB). Other features: The type of moving average can be selected: sma, ema, vwma, wma or rma. An inner band is plotted as an additional indication of approaching extreme levels. Classic BB can also be shown on the graph for the sake of comparison. CALCULATIONS The calculation of BBB is done by adding three different contributions: Standard deviation of price Standard deviation of (price minus moving average) Average of (high - low) over length. RESULTS It looks like BBB follows prices more smoothly (without the typical overshoots of BB). Also, it fits extreme values with higher accuracy. Finally, usually it doesn't cross through prices at less relevant, intermediate higher highs or lower lows, which can be advantageous. See the comparison between red BBB vs blue BB: Both vwma and ema seem to give decent BBB values using the standard length of 20 bars.

2 Length Bollinger BandsThis indicator is a two length Bollinger Band implementation. It uses the Simple Moving Average, and adjusts to the period you are looking at: e.g. if you are looking at the day chart, periods are in days. If you are looking at the 5 minute chart, periods are within 5 minute increments. The foregrounded set of bands is based on the 20 length SMA. So, in the case of the day chart, the successive bands from the middle are 1, 2, 2.5, and 3 standard deviations from the midline (which is a dotted orange line). The upper 2.5 and 3 stddev band is orange and red respectively. When the price gets up into these regions it could indicate a potential sell or short opportunity. The lower 2.5 and 3 stddev bands are colored with lime and green,when the price goes into these regions it indicates a potential buy opportunity. The backgrounded set of bands is based on the 50 length SMA. So, in the case of the day chart, the successive bands from the middle are 1, 2, 2.5, and 3 standard deviations from the midline (which is a dotted purple line). It is intentionally more transparent so as to be seen as a slower background trend, so that the foreground bands (based on the 20 length SMA) can be interpreted within a developing context based on consideration of the slower period. There are many other things to consider with Bollinger Bands, such as the 'squeeze' when the bands get narrow, which is often followed by a 'squeeze' up or down. It is best to consider BBs alongside other indicators (leading & lagging) and with consideration of volume in order to confirm or invalidate your thesis before making a trade.

Multiple Timeframe Bollinger Bands - 15m, 1h, 4h plus currentI could not find any other indicator that does this on TradingView. I like to trade whilst looking at multiple time frames and on my desktop I can do that because I have three monitors. I went on vacation recently and I had to trade using my laptop. It sucked tabbing back and forth so I wrote this script. I personally trade on a 1m chart with indicator data from longer charts so I get the fastest resolution possible. TradingView's horrid and useless idea posting algorithm won't let me post this script in that way so here's a 30 minute chart for posterity. By default it shows only the time frame you are on but you can use the gear icon on the indicator to turn on 15 minute, 1 hour or 4 hour Bollinger bands. There is a color coded guide on the upper right hand side (yay for the new table feature) so you can see what you are getting yourself into. I have 1h bands and current frame (30m) bands on in the picture. Use this on a fast chart with slower bands applied. It doesn't work all that well when you use it on a longer time frame with faster bands applied. I use this one a 1m or 5m chart with 15m and either 1h or 4h bands applied typically. I am making use of this available for free though if you want my code to make adjustments it is available for a small donation to cover my development time; PM me if you are interested. My best bot strategies have all been based on this script so if you want to use this as a jumping off point for your Bollinger band-based strategies this will work well though you do need to buy the code from me for that.

Multiple Timeframe Fib Bollinger Bands - can be used for 3commas*** This idea is based on Bollingers Bands Fibonacci ratios by Shizaru () ** This will look less chaotic if you don't have all four time frames on at once! I left them on for the demo picture just to show them all simultaneously working. This is the basis for most of my bot ideas - indicators from longer chart time frames laid over short time frame charts. What I mean by this is that I like the responsiveness of a 1m chart but indicators from a 1h or 4h chart. There are obviously downsides to doing this or everyone would do it, but I have consistently gotten top results using this method. This is a study, so not a strategy yet but you can use this with 3commas if you convert it to a strategy using band crossover/under points as buy and sell triggers. That is super easy; just follow this excellent guide here which should work for this script: kodify.net It's not super hard if you know a little Pine but if you need help hit me up and we can figure something out. This script by default has 15m, 30m, 1h and 4h settings that are configurable via the gear icon. You can enable or disable any time frame, change the color, etc. I will probably add accurate line labels, custom time frames and adjustable transparency soon. It's advisable to use higher time frame indicator on a lower time frame chart, but not the other way around. I would use these indicators on a 1m chart but not a 1d chart, for example. Have fun and I hope you get some use out of this! I use it for context more than bots but it is definitely possible to use it with both.

SMA&BOLL脚本用来将sma和布林带统一呈现, 方便及时捕捉价格的走势与波动区间. 只要简单地修改SMA的两条线, 布林带的中间线同时作为SMA的第三条长周期参考线也作为布林带的基础计算曲线, 一线双用节省资源. The script is used to present the sma and Bollinger bands in a unified manner, which is convenient to capture the price trend and fluctuation range in time. Just simply modify the two lines of the SMA, and the middle line of the Bollinger bands serves as the third long-period reference line of the SMA and also serves as the Bollinger bands The basic calculation curve, one-line dual-use saves resources.

Bollinger bands on 1M/5M/15M chart onlyJapanese below. 日本語の説明は下記 This is Bollinger bands that is shown only on 1M, 5M and 15M charts only. I Sometimes refer to Bollinger bands when I try to identify specific entry point on lower timeframe especially on 5M, whereas I do not want Bollinger bands to be shown up on other timeframes as they become noise... This is why I removed Bollinger bands from 1 hour and upper timeframes. —————————————————————————————— 1分足、５分足、15分足のみに表示されるボリンジャーバンドのインジケーターです。 1分足や5分足でエントリーのタイミングを計るときにはボリンジャーバンドを使うことがあるのですが、1時間足以上では特に参照しないため、チャートに表示しないよう制御を加えました。 ±1〜3シグマのバンド及びミドルラインとしてSMAを設定可能です。
