Delta Indicators

I would like to see a few different delta indicators.

1. Similar to the Sethmo Price Axis Volume Delta indicator on Tradovate or something better. See pic below with cyan colored arrow and box. Delta on the DOM would also be acceptable.

2. A way to highlight the larger imbalances between bid-ask similar (or better) than the Sethmo Large Delta Bubbles indicator on Tradovate. See pic below with yellow arrows.

3. Not delta related, but I'd like to see the vPOC for each candlestick (yellow bars on each candle below).
