Trend-following and mean-reversion modes, plus a combiner
Five standalone modes are available. SMA crossover and MACD follow trends: they act on a condition that stays true, not on the single instant of a crossing. Bollinger Bands and RSI trade the other way, buying weakness and selling strength. Volume is a confirmation mode, because volume has no direction of its own and can only support a price move already under way.
The sixth mode, combo, runs any selection of the other five and requires them to agree. You choose between unanimous agreement among the active signals and a simple majority of those that currently have a view. There is deliberately no looser "any one of them" option: that is the same thing as running the signals separately, and it would produce more false entries rather than fewer.
