RBI: The EMA of the relative body (RB) of Japanese candles is evaluated. The RB of a candle (my definition) is simply the ratio of the body with respect to its full length and taken positive for bull candles and negative for bear candles: e.g. a bull "marubozo" has RB=1 a bear "marubozo" has RB=-1; a "doji" has RB=0. This simple indicator grasps the essence of the market by filtering out a great deal of noise.
A flag can be selected to calculate its very basic binary version, where a bull candle counts as a one and a bear candle counts as a minus one.
Enter (or exit) the market when the signal line crosses the base line. When the market is choppy we have a kind of alternating bear and bull candles so that RBI is FLAT and usually close to zero. Therefore avoid entering the market when RBI is FLAT and INSIDE the Exclusion level. The exclusion level is to be set by hand: go back in history and check when market was choppy; a good way to set it is to frame the oscillations of RBI whe price was choppy.
RBI is more effective when an EMA of price is used as filtering. I found EMA(13) to be a decent filter: go long when base crosses signal upwards AND closing price is above EMA(13); same concept for going short.
As any other indicator, use it with responsibility: THERE CAN'T BE A SINGLE MAGIC INDICATOR winning all trades.
Above all, have fun.
