I admit that this is inspired from another popular trading system generator, but I found that the strategies it creates are VERY profitable, above the average of what I´ve seen from most other applications in terms profitability. Here is an example of Bollinger Bands and the type of entry rules it uses for it. Interestingly one pattern is repeating a lot and that is the "bar opens below after opening above it" (etc. etc.). I think SQ4 does not have this kind of rule yet, just crossing and closing above / below, but not the "below after above" modes, right? Just an idea as I saw such "out of the box" entry rules to be very profitable there.
One more example for RSI. ("changes direction downward / upward" is the interesting one in this case and I think SQ4 does not have it). This can be applied to all Oscillator type indicators too.
