This Expert Advisor trades on the signal of the Bollinger Bands indicators: it buys at the lower levels when the price rebounds, and
sells at the upper levels. It has the ability to close positions on the reverse signal, take profit or stop loss. Many traders use the
Bollinger Bands indicator, and some use several Bollinger indicators on the same chart at once. In this Expert Advisor, you can
use up to 3 such indicators. When using the first and second indicators, the transaction will be carried out between the lines of these
indicators. The 3rd Bollinger Indicator is used to receive signals from another timeframe (if the timeframe is current, the 3rd
indicator is not used). In addition, to filter strong trend movements, it is possible to use several
moving average lines, so that transactions can be made only according to the trend. Enabling this option can significantly reduce the number of transactions,
but also increase their profitability. The Expert Advisor has a volatility filter based on the ADX indicator and the ability to select hours for trading. It does not
use risky trading methods, and can trade on most currency pairs and timeframes.
