+1 dynamic plotting too

It would be great to use the functionality of STEPWISE for "visual debugging" for both trades and indicators.
The user could define for such "Market Replay" both:
1. step ("bar by bar" or "trade by trade")
2. speed of replay.

There are not many platforms with the Playback functionality and each of them address it in a slightly different way. So it may be worth checking first:
1. Multicharts: https://www.multicharts.com/features/data-playback/
2. NinjaTrader: https://ninjatrader.com/support/helpGuides/nt8/en-us/?playback.htm
3. Sierra Charts: https://www.sierrachart.com/index.php?page=doc/ReplayChart.html
