The trading system that we are going to present below is based on the use of two RSIs, as the name implies, specifically the crossings of two RSIs with different periods (One with a short period and the other with a longer period). As a filter of the signals generated by the crossings, the Fisher indicator is used, which allows having more reliable trading signals, since RSI crossings under certain market conditions can generate false signals and losses that could be avoided with the right filter.
The system itself is not complex. Long positions are opened at the RSI bullish crosses and short positions at the RSI bearish crosses. The Fisher indicator is used as a tool to confirm the different signals.
As always, it is recommended to test the system in a demo account before using it to trade with real money.
