can I see an options spread chart based on bid or ask?

on TOS I can see a chart for an option spread but there is nothing much to read in it on a daily view. I asked support and you can only watch last price on their charts.

Thanks

 

you can have this with IB.
green is ask, white is bid

 

the graph of a RUT july vertical spread 880 900

 

very cool, thanks

one day i will have to try out IB

 

Tradespeed and Obsidian offer that.
