Two Raffs and Bollinger – Raff’s two channels and Bollinger channel


The robot trades according to the trend defined by two Raff channels, which are built on different timeframes. Within the boundaries thus defined, trading is carried out in the Bollinger channel. Disabled martingale and money management are provided, transactions are protected by stop-losses.

Features of the trading strategy – two Raff channels on different timeframes determine the trend, and trading is performed in the Bollinger channel

According to the Hilbert Raff method, two channels are calculated. One channel is built on a higher timeframe, it recognizes a global trend. The second channel is built on a lower timeframe, it recognizes the current trend and determines the boundaries of the trading corridor. Transactions are allowed only in the direction in which the directions of both Raffin channels coincide. Inside the fast Raff Canal, John Bollinger Channel is being built, trading operations are performed in it. Transactions are concluded from one border of the channel in the direction of the other border, and only in the direction of global and local trends. Thus, most of the positions are closed with a profit. Unprofitable positions are averaged by additional transactions, which are calculated so that their aggregate is also closed with a profit. When trading, virtual targets are invisible by the broker. In case of technical failures, real protective targets are provided.
