This 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.
