Hi Bruce, 

I`d like to find two criterias:

WRB (Bullish wide range bar)  on daily chart that have  one or more previuos green bars. (Like FGEN yesterday)

WRB (Bearishwide range bar)  on daily chart that have  one or more previuos red bars. (Like SHOP yerterday) 

Thx, 

Oscar 

I am going to assume you do in fact mean a wide range bar (based on high to low) and not a wide range body (based on open to close). If we also assume a green bar has the close above the open and a red bar has the close below the open (instead of using net change) we get the following.

Bullish Wide Range Bar with at least one previous Green Bar

C > O AND H - L > MAX(H1 - L1, 3) AND CountTrue(C1 > O1, 3) > 0

Bearish Wide Range Bar with at least one previous Red Bar

C < O AND H - L > MAX(H1 - L1, 3) AND CountTrue(C1 < O1, 3) > 0
