Spread and indicators suggestion

Hi, how do I overlay on chart another chart line of index or other pair, I am especially interested to make also custom spreads from CFDs and overlay those as a chart line over a bar chart.
Can you implement this possibility?

Also, can you add indicators, which could be overlayed on chart too like:
- cumulative tick delta and its swing divergences
- highliting bars with certain tick delta threshold
- tick delta divergence
- preciselly pin pointing and highligting a small range, where tick delta / time in seconds is over a threshold
- pace of ticks in histogram or highlighting only a bar with certain speed
- POC of tick volume in bar with value arena zone (cumulative from anchor point for each day until the end or weekly, monthly)

- tick delta profiles (fixed, drawing manually and composite or in zig-zag)
