this fires signals when there is a cross on the BB(13,2) and i also coded up an inverse RSI(5) indicator... only problem is you have to read the signals on the BB's in reverse as I could not overide the generic code and have never bothered with writing my own BB system yet... anywho, this contraption is about 70% hit rate but does best in trends... with recent chop, not so great.
close up with circled example of great signals in late Jan. and early Feb.... the Feb. one especially with TL confluence.
