Bollinger Bands +-3sigma.
You can change period and sigma ratio (Proper size of Deviation is 0.5~1.0).
Bollinger Bands Indicator (BB) is similar to Envelopes. The only difference is that the bands of Envelopes are plotted a fixed distance (%) away from the moving average, while the Bollinger Bands are plotted a certain number of standard deviations away from it. Standard deviation is a measure of volatility, therefore Bollinger Bands adjust themselves to the market conditions. When the markets become more volatile, the bands widen and they contract during less volatile periods.
![Price prediction by Nearest Neighbor found by a weighted correlation coefficient](https://c.mql5.com/i/code/indicator.png)
This indicator finds the nearest neighbor by using a weighted correlation coefficient, in which more recent prices have larger weights. The weight decays linearly from newer to older prices within a price pattern.
![Price prediction by Nearest Neighbor](https://c.mql5.com/i/code/indicator.png)
This indicator uses the Nearest Neighbor clustering technique, also called k-NN, to search for the most similar pattern in history and use its past prices as predictions of the current pattern future prices.

Now it's two-color (or two-mode) trend indicator, the number of calculated bars can be specified.
