When using more than one indicator then all of them must agree, only then signal for buy or sell will be generated.
about OpenOnTick, is a legacy option, I didn't paly with it but basically is doing this:
When a buy or sell order is placed TickPrice is updated so TickPrice = Close[0];
if OpenOnTick is used, next order will be placed only if
Close[0] < TickPrice for buys or
Close[0] > TickPrice for sells
