Indicator Requests - Bar Gaps - Waddah Explosion Candles/Indicator

Can we please get a bar gap indicator? A simple line that shoots out of bar gaps until filled like Al Brooks Bar Gaps between the close of bar 1 and open of bar 2. See white horizontal bars below for NT8 Example. This is in Tview, ATAS, & Sierra as well I believe.

Can we please get a Waddah Attar Explosion Candle add-on or even just a histogram indicator? Kindly see below for waddah explosion overlayed to candles. Same info as the histogram version, but coded for each individual candle.
