As mentioned in the following thread: Y Axis Price Calibration on Rithmic Trader, Although you don’t have the option to “zoom in” you can adjust the Show * bars setting, which will essentially allow you to zoom in and magnify an R Trader Pro chart.
To the second part of your question, I don’t believe you can “link” windows. As an alternative, I would suggest to open a Quote Board and enter the contracts you trade on a frequent basis. Once you have added a few different contracts, you can right-click on that contract and open a new order book, chart, market history, or order tick directly for that contract as shown below:
There are a few platforms that have the option to “link” your chart and quoteboard and DOM so if you click on one contract, the linked widgets will adjust, but I do not believe R Trader or R Trader Pro contains this feature.
I hope this clears things up. Let me know if we were on the same page here!
